This follows the Qt standard, and there is no particular reason why .qdoc files cannot live in src.

Basically anything but a select query will fail. This fixes this by making the user explicitly prepare the query if they want to, and the blame then falls on them if they try and prepare a statement likely to fail. This fix also seems to result in a speedup for single-execution queries, possibly due to reduction in roundtrip communications. All autotests pass & behaviour conforms to documentation. Task-number: 252450, 246125 commit 4612596a6a945ab0199fe06727ff3ea350092ec1 Author: Jason McDonald <jason.mcdonald@nokia.com> Date: Tue Aug 4 14:49:14 2009 +1000 Fix obsolete license headers Reviewed-by: Trust Me commit c3bcc8b094341e0dc768ef5820ba359e2c23436a Author: Aaron Kennedy <aaron.kennedy@nokia.com> Date: Tue Aug 4 10:59:02 2009 +1000 Doc fixes Reviewed-by: TrustMe commit 1d60528ced1f6818a60889d672089bfe4d2290bb Author: Morten Sorvig <msorvig@trolltech.com> Date: Mon Aug 3 15:57:44 2009 +0200 Fix spelling error. commit e99794c1200515f18ffdd0bec9c143db46e009a1 Merge: 199db81 d65f893 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Tue Aug 4 09:24:14 2009 +0200 Merge branch 'master' into doccleanup commit 199db8104a680f91451cf2c93d2d41077b5605bb Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Tue Aug 4 00:04:40 2009 +0200 Fix some headers. commit e8f8193b951a9f9e4b6d309c44151c47b715e901 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Mon Aug 3 23:48:17 2009 +0200 Split the accessibility docu into a "compared to Qt 3" section, and move real information into the overview. commit 8006ec36024e972be21e8397c2cc758a0e9b2ba0 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Mon Aug 3 23:47:37 2009 +0200 The gui-programming seems rather arbitrary and should go away. Some things fit into the desktop integration, which is probably more a howto. Focus is a concept in the widgets context, and application-wide techniques like accelerators should probably be part of the "window" docu. commit 8dab96460280b8af6726905e8d5d24020930b882 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Mon Aug 3 23:45:28 2009 +0200 Move "Getting Started" documentation into getting-started directory. commit 523fd47c29c24a865855d085a0036fc741203930 Merge: a1e50f6 2076f15 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Mon Aug 3 19:10:51 2009 +0200 Merge branch 'master' into doccleanup commit a1e50f6619ff1a302dd1fefbcb6b0cd62a653e7d Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Mon Aug 3 19:06:16 2009 +0200 Group "getting started" documents into a walkthrough structure. commit e393b4f458263cb2f011cc5e5e67cdcc48610ea9 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Mon Aug 3 17:35:15 2009 +0200 Add screenshots for example-overview page. commit 8c84f307f73ab7b77a91e61ed18fdc685afebcc5 Merge: a16033a 34e272a Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Mon Aug 3 11:03:41 2009 +0200 Merge branch 'master' into doccleanup commit a16033a287afe2f494401e24f02f046ec98d944c Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Sun Aug 2 16:57:04 2009 +0200 Link to the real documentation, not just to the modules overview. commit 6c4ed0361c860e738b9344dfb191f55d35b3309f Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Sun Aug 2 16:56:41 2009 +0200 A new layout for the examples. Needs a bit of shuffeling around, and more screenshots and descriptive text for some categories. commit 2dde2faa8f6e86acf738a808412c5e3c21c44658 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Sat Aug 1 22:39:27 2009 +0200 Cleanup the script-related groups a bit. commit a66227d0bed87c633a22a4d155f6a7f0061fc34e Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Sat Aug 1 22:17:16 2009 +0200 Add QContiguousCache to the list of containers as a special case. commit b22133eef28566f1c3c5d57aa0e8272af26da86a Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Sat Aug 1 21:52:37 2009 +0200 Cleaning up groups of text- and string-related classes. Make a clear separation between classes that deal with string data (ie QString, QByteArray, QTextStream) and classes that are part of the "scribe" framework. Merge documentation from the Qt 4.0 introduction of Scribe into the richtext processing guide. commit b30ba739308905b6c06987cec47d4de1e5d172de Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Sat Aug 1 20:50:06 2009 +0200 One group of thread-related classes should be enough. commit a2511650577126026f98cb7416c159498f6f2db5 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Sat Aug 1 19:32:21 2009 +0200 Move documentation for classes into same directory as the respective header files (or implementation file, if one exists). This follows the Qt standard, and there is no particular reason why .qdoc files cannot live in src. Since there are a number of .cpp files that have only documentation it might also be an idea to rename the .qdoc files to .cpp and add them to the .pro-files to have them included in generated project files for easier access. commit f333ad71384cf42c20219a55d9dfa1e29a8c263e Merge: bad9ba5 5aed3db Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Sat Aug 1 12:04:55 2009 +0200 Merge branch 'master' into doccleanup commit bad9ba5468333be2f08da7f28950c980bc63c787 Merge: 49f38b7 c57ed13 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 19:31:04 2009 +0200 Merge branch 'master' into doccleanup commit 49f38b7afe3205eedccf655c0ad749d685cb3d52 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 19:29:46 2009 +0200 Starting to tie together the widgets and layouts groups and documentation. commit e6c4b8316b7c90b19815c0008a282983012c68b3 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 18:43:34 2009 +0200 This is all duplicate information that is better covered in the sql-programming guide. commit 620620ae969bed86d970519bead45762bd39ede1 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 18:37:53 2009 +0200 Consolidate style documentation. commit 01c78ff78888d3ccb50189206b9bcacaf13f5c80 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 17:13:44 2009 +0200 Split plugin-documentation into two: writing plugins and deploying plugins. commit a21f510c982dce06ac1769e61e93574f90cc48c4 Merge: da93c4c c6cdfcb Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 16:04:51 2009 +0200 Merge branch 'master' into doccleanup commit da93c4ccc25dd189dfb9b71bda28bd1e3a7230c1 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 14:19:47 2009 +0200 Some final module cleaning up. commit 9eb0815bbd01b7e30877110b53aa6f82b8e9221d Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 13:51:54 2009 +0200 Move remaining overview groups into one file. commit 65d4c4145386a409aeb1372ae5adc6f3e71e444b Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 13:51:34 2009 +0200 The "io" group should be about file access (be it local or networked). commit 1a3de3a7add6d9e7653e46b57b00852845384a42 Author: Volker Hilsheimer <volker.hilsheimer@nokia.com> Date: Fri Jul 31 13:36:51 2009 +0200 Kill the "time" group.

+    \title Qt Script Debugger Manual
+    \brief A manual describing how to use the Qt Script debugger.
+
+  The Qt Script debugger is a tool for debugging script execution in
+  Qt applications that use Qt Script. Application developers can embed
+  the debugger into their application through the
+  QScriptEngineDebugger class. This manual describes how to use the
+  debugger. We assume that the reader is somewhat familiar with
+  general debugging concepts and existing debugging tools.
+
+  We assume that the debugger has been integrated into the application
+  through the QScriptEngineDebugger::standardWindow()
+  function, which provides the standard debugger configuration.
+
+  \tableofcontents
+
+  \section1 Getting Started
+
+  The following image shows the debugger as created with
+  \l{QScriptEngineDebugger::}{standardWindow()}:
+
+  \image qtscript-debugger.png Running a script under the Qt Script debugger.
+
+  The debugger will start, i.e., take control over the script's
+  execution when any of these conditions are met:
+
+  \list
+    \o The \c{debugger} statement is encountered in the script.
+    \o Clicking the \gui Interrupt menu item from the \gui Debug
+        menu in the main window.
+    \o A breakpoint is reached.
+    \o An uncaught script exception is thrown.
+  \endlist
+
+  Once the debugger is started, the execution state can be inspected,
+  e.g., the value of variables can be queried and the current program
+  stack shown. New breakpoints can be set.
+
+  The debugger will resume, i.e., give the control back to the script
+  engine, when the user clicks \gui Continue menu item from the \gui
+  Debug menu. It will be invoked again if one of the conditions
+  described in the list above is met.
+
+  \section1 Overview of Debugger Components
+
+  The debugger's functionality is divided into a series of components,
+  each being a widget that can be shown in the main window of the
+  debugger. The following table describes each component and how they
+  relate to each other.
+
+  \table
+    \header
+      \o Component
+      \o Description
+  \row
+  \o Console Widget 
+  \o The console widget provides a command-line interface to the
+  debugger's functionality, and also serves as an interactive script
+  interpreter. The set of commands and their syntax is inspired by
+  GDB, the GNU Debugger. Commands and script variables are
+  auto-completed through the TAB key.
+
+  Any console command that causes a change in the debugger or debugger
+  target's state will immediately be reflected in the other debugger
+  components (e.g. breakpoints or local variables changed).
+
+  The console provides a simple and powerful way of manipulating the
+  script environment. For example, typing "x" and hitting enter will
+  evaluate "x" in the current stack frame and display the result.
+  Typing "x = 123" will assign the value 123 to the variable \c{x} in
+  the current scope (or create a global variable \c{x} if there isn't
+  one -- scripts evaluated through the console can have arbitrary side
+  effects, so be careful).
+
+  \row
+  \o Stack Widget
+  \o The stack widget shows a backtrace of the script execution state.
+  Each row represents one frame in the stack. A row contains the
+  frame index (0 being the inner-most frame), the name of the script function,
+  and the location (file name and line number). To select a particular
+  stack frame to inspect, click on its row.
+
+  \row
+  \o Locals Widget
+  \o The locals widget shows the variables that are local to the
+  currently selected stack frame; that is, the properties of the
+  objects in the scope chain and the \c{this}-object. Objects can be
+  expanded, so that their properties can be examined, recursively.
+  Properties whose value has changed are shown in bold font.
+
+  Properties that are not read-only can be edited. Double-click on the
+  value and type in the new value; the value can be an arbitrary
+  expression. The expression will be evaluated in the associated stack
+  frame. While typing, you can press the TAB key to get possible
+  completions for the expression.
+
+  \row
+  \o Code Widget
+  \o The code widget shows the code of the currently selected script.
+    The widget displays an arrow in the left margin, marking the
+    code line that is being executed.
+    Clicking in the margin of a line will cause a breakpoint to be
+    toggled at that line. A breakpoint has to be set on a line that
+    contains an actual statement in order to be useful.When an uncaught script exception occurs, the
+    offending line will be shown with a red background.
+
+    The code widget is read-only; it cannot currently be used to edit
+    and (re)evaluate scripts. This is however possible from the
+    command-line interface, see \l{Console Command Reference}.
+
+  \row
+  \o Scripts Widget
+
+  \o The scripts widget shows the scripts that are currently loaded in
+  the script engine. Clicking on a script will cause its code to be
+  shown in the code widget. When a script is no longer referenced by
+  the debugger target it is removed from the scripts widget. Code
+  evaluated through QScriptEngine::evaluate() without a name specified, will be
+  displayed in the widget as Anonymous.
+
+  \row
+    \o Breakpoints Widget
+
+  \o The breakpoints widget shows all the breakpoints that are set.  A
+  breakpoint can be disabled or enabled by clicking the checkbox next
+  to the breakpoint's ID (the ID is provided so that the breakpoint
+  can be manipulated through the console widget as well).
+
+  A condition can be associated with the breakpoint; the condition can
+  be an arbitrary expression that should evaluate to true or
+  false. The breakpoint will only be triggered when its location is
+  reached \bold{and} the condition evaluates to true.
+
+  Similarly, if the breakpoint's ignore-count is set to N, the
+  breakpoint will be ignored the next N times it is hit.
+
+  A new breakpoint can be set by clicking the New Breakpoint button
+  and typing in a location of the form <filename>\bold{:}<linenumber>.
+  The breakpoint location can refer to an already loaded script, or
+  one that has not been loaded yet.
+
+  \row
+  \o Debug Output Widget
+  \o The debug output widget shows messages generated by the print()
+  script function. Scripts can use the special variables \c{__FILE__}
+  and \c{__LINE__} to include the current location information in the
+  messages.
+
+  \row
+  \o Error Log Widget
+  \o The error log widget shows error messages that have been generated.
+     All uncaught exceptions that occur in the engine will appear here.
+
+  \endtable
+
+  \section2 Resuming Script Evaluation
+
+  Script evaluation can be resumed in one of the following ways:
+
+  \list
+  \o \bold{Continue}: Evaluation will resume normally.
+  \o \bold{Step Into}: Evaluation will resume until the next statement is reached.
+  \o \bold{Step Over}: Evaluation will resume until the next statement is reached;
+                but if the current statement is a function call, the debugger
+                will treat it as a single statement.
+  \o \bold{Step Out}: Evaluation will resume until the current function exits and
+               the next statement is reached.
+  \o \bold{Run to Cursor}: Run until the statement at the cursor is reached.
+  \o \bold{Run to New Script}: Run until the first statement of a new script is reached.
+  \endlist
+
+  In any case, script evaluation can also be stopped due to either of the
+  following reasons:
+
+  \list
+  \o A \c{debugger} statement is encountered.
+  \o A breakpoint is hit.
+  \o An uncaught script exception occurs.
+  \endlist
+
+  \section2 Resuming After an Uncaught Exception
+
+  When an uncaught script exception occurs, it is not possible to
+  continue evaluating the current function normally. However, you can
+  use the console command \bold{return} to catch the exception and
+  return a value to the calling function.
+
+  \section1 Console Command Reference
+
+  Note that you can also get help on the available commands by typing
+  ".help" in the console.
+
+  \section2 Breakpoint-related Commands
+
+  Break points is set
+
+  \section3 break <location>
+
+  Sets a breakpoint at a given code line.
+
+  \code
+  .break foo.qs:123
+  \endcode
+
+  This command sets a breakpoint at \c{foo.qs}, line 123.
+
+  \code
+  .break 123
+  \endcode
+
+  This command sets a breakpoint at line 123 in the current script; the current script
+  is the script associated with the current stack frame.
+
+  Each breakpoint has a unique identifier (an integer) associated with it.
+  This identifier is needed by other breakpoint-related commands.
+
+  \section3 clear <location>
+
+  \code
+  .clear foo.qs:123
+  \endcode
+
+  clears (deletes) the breakpoint at \c{foo.qs}, line 123.
+
+  \code
+  clear 123
+  \endcode
+
+  clears (deletes) the breakpoint at line 123 in the current script;
+  the current script is the script associated with the current stack
+  frame.
+
+  \section3 condition <breakpoint-id> <expression>
+
+  Sets a condition for a breakpoint.
+
+  \code
+  .condition 1 i > 42
+  \endcode
+
+  specifies that breakpoint 1 should only be triggered if the variable \c{i}
+  is greater than 42.
+
+  The expression can be an arbitrary one, i.e. it can have
+  side-effects. It can be any valid QScript conditional
+  expression.
+
+  \section3 delete <breakpoint-id>
+
+  Deletes a breakpoint, i.e., removes it from the current debugging
+  session.
+
+  \section3 disable <breakpoint-id>
+
+  Disables a breakpoint. The breakpoint will continue to exist, but
+  will not stop program execution.
+
+  \section3 enable <breakpoint-id>
+
+  Enables a breakpoint. Breakpoints are enabled by default, so you
+  only need to use this command if you have disabled to breakpoint
+  previously.
+
+  \section3 ignore <breakpoint-id> <count>
+  
+  Sets the ignore-count of a breakpoint, i.e., the breakpoint will not
+  stop the program execution unless it have been reached \c count
+  times. This can, for instance, be useful in loops to stop at a
+  specific iteration.
+
+  \code
+  .ignore 1 5
+  \endcode
+
+  Specifies that breakpoint 1 should be ignored the next 5 times it is
+  hit.
+
+  \section3 info breakpoints
+
+  Lists the breakpoints that are set.
+
+  \code
+    .info breakpoints
+  \endcode
+
+  \section3 tbreak <location>
+
+  Sets a temporary breakpoint. This command is identical to the
+  \c{break} command, only the breakpoint will be automatically deleted
+  the first time it is hit.
+
+  \section2 File-related Commands
+
+  \section3 list <location>
+
+  Lists the contents of a script around a given location, where the
+  location is given as a line number and, optionally, the name of the
+  file from which you will print. If only a line number is given, \c
+  {.list} will use the file of the current stack frame.
+
+  \code
+    .list foo.qs:125
+  \endcode
+
+  When no arguments are given, \c{list} will incrementally list
+  sections of the current script.
+
+  \section3 info scripts
+
+  Lists the scripts that are currently loaded.
+
+  \section2 Execution-related Commands
+
+  \section3 advance <location>
+
+  Advances execution to a given location. The syntax of the location
+  is the same as for setting breakpoints. For example:
+
+  \code
+    .advance foo.qs:125
+  \endcode
+
+  \section3 continue
+
+  Continues execution normally, i.e, gives the execution control over
+  the script back to the QScriptEngine.
+
+  \section3 eval <program>
+
+  Evaluates a program. 
+
+  \section3 finish
+
+  Continues execution until the current function exits and the next
+  statement is reached (i.e., the statement after the call to the
+  function).
+
+  \section3 interrupt
+
+  Requests that execution should be interrupted. Interruption will
+  occur as soon as a new script statement is reached.
+
+  \section3 next <count = 1>
+
+  Continues execution until a new statement is reached; but if the
+  current statement is a function call, the function call will be
+  treated as a single statement. This will be done \c count times
+  before execution is stopped; the default is one.
+
+  \section3 return <expression>
+
+  Makes the current frame return to its caller. If \c expression is
+  given, it will sent as the result of the function (i.e., replacing
+  the functions return value). \c expression can be any valid QScript
+  expression.
+
+  \section3 step <count = 1>
+
+  Continues execution until a new statement is reached. If the number
+  \c count is given as argument, this will be done \c count times
+  before execution is stopped. As opposed to \l{next <count = 1>},  \c
+  step will enter functions when encountering a function call
+  statement.
+
+  \section2 Stack-related Commands
+
+  \section3 backtrace
+
+  Shows a backtrace of the current execution. The trace will list the
+  function name and its position in the script for each stack frame.
+
+  \section3 down
+
+  Selects the previous (inner) stack frame. The execution will not
+  return to this frame, but you will get access to its local
+  variables. 
+
+  \section3 frame <index>
+
+  This command moves to the stack frame with the given \c index. The
+  index of the frame on the top of the stack is 0. Previous frames are
+  numbered from 1 and upwards (the bottom frame in the stack has the
+  largest index).
+
+  \section3 info locals
+
+  Lists the variables that are in the scope of the current frame.
+
+  \section3 up
+
+  Selects the next (outer) stack frame.

+/*!
+    \page qtscriptextensions.html
+    \title Creating QtScript Extensions
+    \brief A guide to creating and using QtScript extensions.
+
+    QtScript extensions can make additional functionality available to scripts
+    evaluated by a QScriptEngine. Extensions are imported by calling
+    the QScriptEngine::importExtension() function.
+
+    There are three ways to create an extension:
+
+    \list
+    \o Subclass QScriptExtensionPlugin and implement the desired functionality.
+    \o Implement the functionality in a script file.
+    \o Use a hybrid approach, where part of the functionality is implemented in a
+       QScriptExtensionPlugin, and part is implemented in a script file.
+    \endlist
+
+    The (dot-qualified) extension name is used to determine the path (relative to
+    the application's plugin path) where QScriptEngine will look for the script
+    file that will initialize the extension; if a file called \c{__init__.js}
+    (usually located in \c{[application plugin path]/script/foo/}) is
+    found in the corresponding folder, its contents will be evaluated by the engine
+    when the extension is imported.
+    As an example, if the extension is called \c{"foo.bar.baz"}, the engine will look
+    for \c{__init__.js} in \c{foo/bar/baz}. Additionally, before importing
+    \c{"foo.bar.baz"}, the engine will ensure that the extensions \c{"foo"} and \c{"foo.bar"}
+    are imported, locating and evaluating the corresponding \c{__init__.js}
+    in the same manner (in folders \c{foo} and \c{foo/bar}, respectively).
+
+    The contents of \c{__init__.js} are evaluated in a new QScriptContext,
+    as if it were the body of a function. The engine's Global Object acts as
+    the \c{this} object. The following local variables are initially available
+    to the script:
+
+    \list
+    \o \bold{__extension__}: The name of the extension (e.g. \c{"foo.bar.baz"}).
+    \o \bold{__setupPackage__}: A convenience function for setting up a "namespace" in the script environment. A typical application is to call \c{__setupPackage__()} with \c{__extension__} as argument; e.g. \c{__setupPackage__("foo.bar.baz")} would ensure that the object chain represented by the expression \c{foo.bar.baz} exists in the script environment. (This function is semantically equivalent to QScriptExtensionPlugin::setupPackage().)
+    \o \bold{__postInit__}: By default, this variable is undefined. If you assign a function to it, that function will be called \bold{after} the C++ plugin's initialize() function has been called. You can use this to perform further initialization that depends on e.g. native functions that the C++ plugin registers.
+    \endlist
+
+    An example of a simple \c{__init__.js}:
+
+    \snippet doc/src/snippets/code/doc_src_qtscriptextensions.qdoc 0
+
+    QScriptEngine will look for a QScriptExtensionPlugin that provides
+    the relevant extension by querying each plugin for its keys()
+    until a match is found. The plugin's initialize() function will be
+    called \bold{after} the relevant \c{__init__.js} (if any) has been
+    evaluated.
+
+    Continuining with the example of our imaginary extension \c{"foo.bar.baz"},
+    the following steps will be performed by QScriptEngine::importExtension():
+
+    \list
+    \o If it exists, \c{foo/__init__.js} is evaluated.
+    \o If a plugin with \c{"foo"} in its list of keys is found, its initialize() function is called with \c{"foo"} as key.
+    \o If it exists, \c{foo/bar/__init__.js} is evaluated.
+    \o If a plugin with \c{"foo.bar"} in its list of keys is found, its initialize() function is called with \c{"foo.bar"} as key.
+    \o If it exists, \c{foo/bar/baz/__init__.js} is evaluated.
+    \o If a plugin with "foo.bar.baz" in its list of keys is found, its initialize() function is called with \c{"foo.bar.baz"} as key.
+    \endlist
+
+    \section1 Static Extensions
+
+    When an extension is compiled and linked into your application as a
+    static plugin, Qt Script will look for the optional \c{__init__.js}
+    script in a resource, prefixed by \c{:/qtscriptextension}. For example,
+    if the extension key is "foo.bar", Qt Script will evaluate the contents
+    of the file \c{:/qtscriptextension/foo/bar/__init__.js}, if it
+    exists. Note that if the resource is built into the plugin, you may
+    need to use the Q_INIT_RESOURCE() macro to initialize the resource
+    before importing the extension.

+  The following classes add scripting capabilities to Qt applications.
+
+  \annotatedlist script
+
+  \section1 Language Overview
+
+  Qt Script is based on the ECMAScript scripting language, as defined
+  in standard \l{ECMA-262}. Microsoft's JScript, and Netscape's
+  JavaScript are also based on the ECMAScript standard. For an
+  overview of ECMAScript, see the
+  \l{ECMAScript Reference}{ECMAScript reference}.
+  If you are not familiar with the ECMAScript language, there are
+  several existing tutorials and books that cover this subject, such
+  as \l{JavaScript: The Definitive Guide}.
+
+  Existing users of \l{Qt Script for Applications (QSA)} may find the
+  \l{Moving from QSA to Qt Script} document useful when porting
+  QSA scripts to Qt Script.
+
+  \section1 Basic Usage
+
+  To evaluate script code, you create a QScriptEngine and call its
+  evaluate() function, passing the script code (text) to evaluate
+  as argument.
+
+  \snippet doc/src/snippets/qtscript/evaluation/main.cpp 0
+
+  The return value will be the result of the evaluation (represented
+  as a QScriptValue object); this can be converted to standard C++
+  and Qt types.
+
+  Custom properties can be made available to scripts by registering
+  them with the script engine. This is most easily done by setting
+  properties of the script engine's \e{Global Object}:
+
+  \snippet doc/src/snippets/qtscript/registeringvalues/main.cpp 0
+
+  This places the properties in the script environment, thus making them
+  available to script code.
+
+  \section1 Making a QObject Available to the Script Engine
+
+  Any QObject-based instance can be made available for use with scripts.
+
+  When a QObject is passed to the QScriptEngine::newQObject() function,
+  a Qt Script wrapper object is created that can be used to make the
+  QObject's signals, slots, properties, and child objects available
+  to scripts.
+
+  Here's an example of making an instance of a QObject subclass
+  available to script code under the name \c{"myObject"}:
+
+  \snippet doc/src/snippets/qtscript/registeringobjects/main.cpp 0
+
+  This will create a global variable called \c{myObject} in the
+  script environment. The variable serves as a proxy to the
+  underlying C++ object. Note that the name of the script variable
+  can be anything; i.e., it is not dependent upon QObject::objectName().
+
+  The \l{QScriptEngine::}{newQObject()} function accepts two additional
+  optional arguments: one is the ownership mode, and the other is a
+  collection of options that allow you to control certain aspects of how
+  the QScriptValue that wraps the QObject should behave. We will come
+  back to the usage of these arguments later.
+
+  \section2 Using Signals and Slots
+
+  Qt Script adapts Qt's central \l{Signals and Slots} feature for
+  scripting. There are three principal ways to use signals and slots
+  with Qt Script:
+
+  \list
+  \i \bold{Hybrid C++/script}: C++ application code connects a
+  signal to a script function. The script function can, for example, be
+  a function that the user has typed in, or one that you have read from a
+  file. This approach is useful if you have a QObject but don't want
+  to expose the object itself to the scripting environment; you just
+  want a script to be able to define how a signal should be reacted
+  to, and leave it up to the C++ side of your application to establish
+  the connection.
+
+  \i \bold{Hybrid script/C++}: A script can connect signals and slots
+  to establish connections between pre-defined objects that the
+  application exposes to the scripting environment. In this scenario,
+  the slots themselves are still written in C++, but the definition of
+  the connections is fully dynamic (script-defined).
+
+  \i \bold{Purely script-defined}: A script can both define signal
+  handler functions (effectively "slots written in Qt Script"),
+  \e{and} set up the connections that utilize those handlers. For
+  example, a script can define a function that will handle the
+  QLineEdit::returnPressed() signal, and then connect that signal to the
+  script function.
+  \endlist
+
+  Use the qScriptConnect() function to connect a C++ signal to a
+  script function. In the following example a script signal handler is
+  defined that will handle the QLineEdit::textChanged() signal:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 47
+
+  The first two arguments to qScriptConnect() are the same
+  as you would pass to QObject::connect() to establish a normal C++
+  connection. The third argument is the script object that will act
+  as the \c this object when the signal handler is invoked; in the above
+  example we pass an invalid script value, so the \c this object will
+  be the Global Object. The fourth argument is the script function
+  ("slot") itself. The following example shows how the \c this argument
+  can be put to use:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 48
+
+  We create two QLineEdit objects and define a single signal handler
+  function. The connections use the same handler function, but the
+  function will be invoked with a different \c this object depending on
+  which object's signal was triggered, so the output of the print()
+  statement will be different for each.
+
+  In script code, Qt Script uses a different syntax for connecting to
+  and disconnecting from signals than the familiar C++ syntax; i.e.,
+  QObject::connect().
+  To connect to a signal, you reference the relevant signal as a property
+  of the sender object, and invoke its \c{connect()} function. There
+  are three overloads of \c{connect()}, each with a corresponding
+  \c{disconnect()} overload. The following subsections describe these
+  three forms.
+
+  \section3 Signal to Function Connections
+
+  \c{connect(function)}
+
+  In this form of connection, the argument to \c{connect()} is the
+  function to connect to the signal.
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 2
+
+  The argument can be a Qt Script function, as in the above
+  example, or it can be a QObject slot, as in
+  the following example:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 3
+
+  When the argument is a QObject slot, the argument types of the
+  signal and slot do not necessarily have to be compatible;
+  QtScript will, if necessary, perform conversion of the signal
+  arguments to match the argument types of the slot.
+
+  To disconnect from a signal, you invoke the signal's
+  \c{disconnect()} function, passing the function to disconnect
+  as argument:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 4
+
+  When a script function is invoked in response to a signal, the
+  \c this object will be the Global Object.
+
+  \section3 Signal to Member Function Connections
+
+  \c{connect(thisObject, function)}
+
+  In this form of the \c{connect()} function, the first argument
+  is the object that will be bound to the variable, \c this, when
+  the function specified using the second argument is invoked.
+
+  If you have a push button in a form, you typically want to do
+  something involving the form in response to the button's
+  \c{clicked} signal; passing the form as the \c this object
+  makes sense in such a case.
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 5
+
+  To disconnect from the signal, pass the same arguments to \c{disconnect()}:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 6
+
+  \section3 Signal to Named Member Function Connections
+
+  \c{connect(thisObject, functionName)}
+
+  In this form of the \c{connect()} function, the first argument is
+  the object that will be bound to the variable, \c this, when
+  a function is invoked in response to the signal. The second argument
+  specifies the name of a function that is connected to the signal,
+  and this refers to a member function of the object passed as the
+  first argument (\c thisObject in the above scheme).
+
+  Note that the function is resolved when the connection is made, not
+  when the signal is emitted.
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 7
+
+  To disconnect from the signal, pass the same arguments to \c{disconnect()}:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 8
+
+  \section3 Error Handling
+
+  When \c{connect()} or \c{disconnect()} succeeds, the function will
+  return \c{undefined}; otherwise, it will throw a script exception.
+  You can obtain an error message from the resulting \c{Error} object.
+  Example:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 9
+
+  \section3 Emitting Signals from Scripts
+
+  To emit a signal from script code, you simply invoke the signal
+  function, passing the relevant arguments:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 10
+
+  It is currently not possible to define a new signal in a script;
+  i.e., all signals must be defined by C++ classes.
+
+  \section3 Overloaded Signals and Slots
+
+  When a signal or slot is overloaded, QtScript will attempt to
+  pick the right overload based on the actual types of the QScriptValue arguments
+  involved in the function invocation. For example, if your class has slots
+  \c{myOverloadedSlot(int)} and \c{myOverloadedSlot(QString)}, the following
+  script code will behave reasonably:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 11
+
+  You can specify a particular overload by using array-style property access
+  with the \l{QMetaObject::normalizedSignature()}{normalized signature} of
+  the C++ function as the property name:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 12
+
+  If the overloads have different number of arguments, QtScript will
+  pick the overload with the argument count that best matches the
+  actual number of arguments passed to the slot.
+
+  For overloaded signals, Qt Script will throw an error if you try to connect
+  to the signal by name; you have to refer to the signal with the full
+  normalized signature of the particular overload you want to connect to.
+
+  \section2 Accessing Properties
+
+  The properties of the QObject are available as properties
+  of the corresponding QtScript object. When you manipulate
+  a property in script code, the C++ get/set method for that
+  property will automatically be invoked. For example, if your
+  C++ class has a property declared as follows:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 13
+
+  then script code can do things like the following:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 14
+
+  \section2 Accessing Child QObjects
+
+  Every named child of the QObject (that is, for which
+  QObject::objectName() is not an empty string) is by default available as
+  a property of the QtScript wrapper object. For example,
+  if you have a QDialog with a child widget whose \c{objectName} property is
+  \c{"okButton"}, you can access this object in script code through
+  the expression
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 15
+
+  Since \c{objectName} is itself a Q_PROPERTY, you can manipulate
+  the name in script code to, for example, rename an object:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 16
+
+  You can also use the functions \c{findChild()} and \c{findChildren()}
+  to find children. These two functions behave identically to
+  QObject::findChild() and QObject::findChildren(), respectively.
+
+  For example, we can use these functions to find objects using strings
+  and regular expressions:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 17
+
+  You typically want to use \c{findChild()} when manipulating a form
+  that uses nested layouts; that way the script is isolated from the
+  details about which particular layout a widget is located in.
+
+  \section2 Controlling QObject Ownership
+
+  Qt Script uses garbage collection to reclaim memory used by script
+  objects when they are no longer needed; an object's memory can be
+  automatically reclaimed when it is no longer referenced anywhere in
+  the scripting environment. Qt Script lets you control what happens
+  to the underlying C++ QObject when the wrapper object is reclaimed
+  (i.e., whether the QObject is deleted or not); you do this when you
+  create an object by passing an ownership mode as the second argument
+  to QScriptEngine::newQObject().
+
+  Knowing how Qt Script deals with ownership is important, since it can
+  help you avoid situations where a C++ object isn't deleted when it
+  should be (causing memory leaks), or where a C++ object \e{is}
+  deleted when it shouldn't be (typically causing a crash if C++ code
+  later tries to access that object).
+
+  \section3 Qt Ownership
+
+  By default, the script engine does not take ownership of the
+  QObject that is passed to QScriptEngine::newQObject(); the object
+  is managed according to Qt's object ownership (see
+  \l{Object Trees and Object Ownership}). This mode is appropriate
+  when, for example, you are wrapping C++ objects that are part of
+  your application's core; that is, they should persist regardless of
+  what happens in the scripting environment. Another way of stating
+  this is that the C++ objects should outlive the script engine.
+
+  \section3 Script Ownership
+
+  Specifying QScriptEngine::ScriptOwnership as the ownership mode
+  will cause the script engine to take full ownership of the QObject
+  and delete it when it determines that it is safe to do so
+  (i.e., when there are no more references to it in script code).
+  This ownership mode is appropriate if the QObject does not have a
+  parent object, and/or the QObject is created in the context of the
+  script engine and is not intended to outlive the script engine.
+
+  For example, a constructor function that constructs QObjects
+  only to be used in the script environment is a good candidate:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 18
+
+  \section3 Auto-Ownership
+
+  With QScriptEngine::AutoOwnership the ownership is based on whether
+  the QObject has a parent or not.
+  If the QtScript garbage collector finds that the QObject is no
+  longer referenced within the script environment, the QObject will
+  be deleted \e{only} if it does not have a parent.
+
+  \section3 What Happens When Someone Else Deletes the QObject?
+
+  It is possible that a wrapped QObject is deleted outside of
+  Qt Script's control; i.e., without regard to the ownership mode
+  specified. In this case, the wrapper object will still
+  be an object (unlike the C++ pointer it wraps, the script object
+  won't become null). Any attempt to access properties of the script
+  object will, however, result in a script exception being thrown.
+
+  Note that QScriptValue::isQObject() will still return true for a
+  deleted QObject, since it tests the type of the script object, not
+  whether the internal pointer is non-null. In other words, if
+  QScriptValue::isQObject() returns true but QScriptValue::toQObject()
+  returns a null pointer, this indicates that the QObject has been
+  deleted outside of Qt Script (perhaps accidentally).
+
+  \section2 Customizing Access to the QObject
+
+  QScriptEngine::newQObject() can take a third argument which allows
+  you to control various aspects of the access to the QObject through
+  the QtScript wrapper object it returns.
+
+  QScriptEngine::ExcludeChildObjects specifies that child objects of
+  the QObject should not appear as properties of the wrapper object.
+
+  QScriptEngine::ExcludeSuperClassProperties and
+  QScriptEngine::ExcludeSuperClassMethods can be used to avoid
+  exposing members that are inherited from the QObject's superclass.
+  This is useful for defining a "pure" interface where inherited members
+  don't make sense from a scripting perspective; e.g., you don't want
+  script authors to be able to change the \c{objectName} property of
+  the object or invoke the \c{deleteLater()} slot.
+
+  QScriptEngine::AutoCreateDynamicProperties specifies that properties
+  that don't already exist in the QObject should be created as dynamic
+  properties of the QObject, rather than as properties of the QtScript
+  wrapper object. If you want new properties to truly become persistent
+  properties of the QObject, rather than properties that are destroyed
+  along with the wrapper object (and that aren't shared if the QObject
+  is wrapped multiple times with QScriptEngine::newQObject()), you
+  should use this option.
+
+  QScriptEngine::SkipMethodsInEnumeration specifies that signals and
+  slots should be skipped when enumerating the properties of the QObject
+  wrapper in a for-in script statement. This is useful when defining
+  prototype objects, since by convention function properties of
+  prototypes should not be enumerable.
+
+  \section2 Making a QObject-based Class New-able from a Script
+
+  The QScriptEngine::newQObject() function is used to wrap an
+  existing QObject instance, so that it can be made available to
+  scripts. A different scenario is that you want scripts to be
+  able to construct new objects, not just access existing ones.
+
+  The Qt meta-type system currently does not provide dynamic
+  binding of constructors for QObject-based classes. If you want to
+  make such a class new-able from scripts, Qt Script can generate
+  a reasonable script constructor for you; see
+  QScriptEngine::scriptValueFromQMetaObject().
+
+  You can also use QScriptEngine::newFunction() to wrap your own
+  factory function, and add it to the script environment; see
+  QScriptEngine::newQMetaObject() for an example.
+
+  \section2 Enum Values
+
+  Values for enums declared with Q_ENUMS are not available as
+  properties of individual wrapper objects; rather, they are
+  properties of the QMetaObject wrapper object that can be created
+  with QScriptEngine::newQMetaObject().
+
+  \section1 Conversion Between QtScript and C++ Types
+
+  QtScript will perform type conversion when a value needs to be
+  converted from the script side to the C++ side or vice versa; for
+  instance, when a C++ signal triggers a script function, when
+  you access a QObject property in script code, or when
+  you call QScriptEngine::toScriptValue() or
+  QScriptEngine::fromScriptValue() in C++. QtScript provides default
+  conversion operations for many of the built-in Qt types. You can
+  change the conversion operation for a type (including your custom
+  C++ types) by registering your own conversion functions with
+  qScriptRegisterMetaType().
+
+  \section2 Default Conversion from Qt Script to C++
+
+  The following table describes the default conversion from a
+  QScriptValue to a C++ type.

+               the result is an empty QList<int>.
+    \endtable
+
+  Additionally, QtScript will handle the following cases:
+
+  \list
+  \i If the QScriptValue is a QObject and the target type name ends with
+     \c * (i.e., it is a pointer), the QObject pointer will be cast to the
+     target type with qobject_cast().
+  \i If the QScriptValue is a QVariant and the target type name ends with
+     \c * (i.e., it is a pointer), and the \l{QVariant::userType()}{userType()}
+     of the QVariant is the type that the target type points to, the result
+     is a pointer to the QVariant's data.
+  \i If the QScriptValue is a QVariant and it can be converted to the
+     target type (according to QVariant::canConvert()), the QVariant will
+     be cast to the target type with qvariant_cast().
+  \endlist

+               QScriptEngine::newQObject() for each element of the list.
+    \row    \o QList<int> \o A new script array (created with

+               element of the list.

+  Other types (including custom types) will be wrapped using
+  QScriptEngine::newVariant(). For null pointers of any type, the
+  result is QScriptEngine::nullValue().
+
+  \section1 How to Design and Implement Application Objects
+
+  This section explains how to implement application objects and
+  provides the necessary technical background material.
+
+  \section2 Making a C++ object available to Scripts Written in QtScript
+
+  Making C++ classes and objects available to a scripting language is
+  not trivial because scripting languages tend to be more dynamic than
+  C++, and it must be possible to introspect objects (query information
+  such as function names, function signatures, properties, etc., at
+  run-time). Standard C++ does not provide features for this.
+
+  We can achieve the functionality we want by extending C++, using
+  C++'s own facilities so our code is still standard C++. The Qt
+  meta-object system provides the necessary additional functionality.
+  It allows us to write using an extended C++ syntax, but converts this
+  into standard C++ using a small utility program called \l{moc}
+  (Meta-Object Compiler). Classes that wish to take advantage of the
+  meta-object facilities are either subclasses of QObject, or use the
+  \c{Q_OBJECT} macro. Qt has used this approach for many years and it has
+  proven to be solid and reliable. QtScript uses this meta-object
+  technology to provide scripters with dynamic access to C++ classes
+  and objects.
+
+  To completely understand how to make C++ objects available to Qt
+  Script, some basic knowledge of the Qt meta-object system is very
+  helpful. We recommend that you read the \l{Qt Object Model}. The
+  information in this document and the documents it links to are very
+  useful for understanding how to implement application objects.
+
+  However, this knowledge is not essential in the simplest cases.
+  To make an object available in QtScript, it must derive from
+  QObject. All classes which derive from QObject can be introspected
+  and can provide the information needed by the scripting engine at
+  run-time; e.g., class name, functions, signatures. Because we obtain
+  the information we need about classes dynamically at run-time, there
+  is no need to write wrappers for QObject derived classes.
+
+  \section2 Making C++ Class Member Functions Available in QtScript
+
+  The meta-object system also makes information about signals and slots
+  dynamically available at run-time. By default, for QObject subclasses,
+  only the signals and slots are automatically made available to scripts.
+  This is very convenient because, in practice, we normally only want to
+  make specially chosen functions available to scripters. When you create
+  a QObject subclass, make sure that the functions you want to expose to
+  QtScript are public slots.
+
+  For example, the following class definition enables scripting only for
+  certain functions:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 19
+
+  In the example above, aNonScriptableFunction() is not declared as a
+  slot, so it will not be available in QtScript. The other three
+  functions will automatically be made available in QtScript because
+  they are declared in the \c{public slots} section of the class
+  definition.
+
+  It is possible to make any function script-invokable by specifying
+  the \c{Q_INVOKABLE} modifier when declaring the function:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 20
+
+  Once declared with \c{Q_INVOKABLE}, the method can be invoked from
+  QtScript code just as if it were a slot. Although such a method is
+  not a slot, you can still specify it as the target function in a
+  call to \c{connect()} in script code; \c{connect()} accepts both
+  native and non-native functions as targets.
+
+  \section2 Making C++ Class Properties Available in QtScript
+
+  In the previous example, if we wanted to get or set a property using
+  QtScript we would have to write code like the following:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 21
+
+  Scripting languages often provide a property syntax to modify and
+  retrieve properties (in our case the enabled state) of an
+  object. Many script programmers would want to write the above code
+  like this:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 22
+
+  To make this possible, you must define properties in the C++ QObject
+  subclass. For example, the following \c MyObject class declaration
+  declares a boolean property called \c enabled, which uses the function
+  \c{setEnabled(bool)} as its setter function and \c{isEnabled()} as its
+  getter function:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 23
+
+  The only difference from the original code is the use of the macro
+  \c{Q_PROPERTY}, which takes the type and name of the property, and
+  the names of the setter and getter functions as arguments.
+
+  If you don't want a property of your class to be accessible in
+  QtScript, you set the \c{SCRIPTABLE} attribute to \c false when
+  declaring the property; by default, the \c{SCRIPTABLE} attribute is
+  \c true. For example:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 24
+
+  \section2 Reacting to C++ Objects Signals in Scripts
+
+  In the Qt object model, signals are used as a notification mechanism
+  between QObjects. This means one object can connect a signal to
+  another object's slot and, every time the signal is emitted, the slot
+  is called. This connection is established using the QObject::connect()
+  function.
+
+  The signals and slots mechanism is also available to QtScript
+  programmers. The code to declare a signal in C++ is the same,
+  regardless of whether the signal will be connected to a slot in C++
+  or in QtScript.
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 25
+
+  The only change we have made to the code in the previous section is
+  to declare a signals section with the relevant signal. Now, the
+  script writer can define a function and connect to the object like
+  this:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 26
+
+  \section2 Design of Application Objects
+
+  The previous section described how to implement C++ objects which
+  can be used in QtScript. Application objects are the same kind of
+  objects, and they make your application's functionality available to
+  QtScript scripters.  Since the C++ application is already written
+  in Qt, many objects are already QObjects. The easiest approach would
+  be to simply add all these QObjects as application objects to the
+  scripting engine. For small applications this might be sufficient,
+  but for larger applications this is probably not the right
+  approach. The problem is that this method reveals too much of the
+  internal API and gives script programmers access to application
+  internals which should not be exposed.
+
+  Generally, the best way of making application functionality available
+  to scripters is to code some QObjects which define the applications
+  public API using signals, slots, and properties. This gives you
+  complete control of the functionality made available by the
+  application. The implementations of these objects simply call the
+  functions in the application which do the real work. So, instead of
+  making all your QObjects available to the scripting engine, just add
+  the wrapper QObjects.
+
+  \section3 Returning QObject Pointers
+
+  If you have a slot that returns a QObject pointer, you should note
+  that, by default, Qt Script only handles conversion of the types
+  QObject* and QWidget*. This means that if your slot is declared
+  with a signature like "MyObject* getMyObject()", QtScript doesn't
+  automatically know that MyObject* should be handled in the same way
+  as QObject* and QWidget*. The simplest way to solve this is to only
+  use QObject* and QWidget* in the method signatures of your scripting
+  interface.
+
+  Alternatively, you can register conversion functions for your custom
+  type with the qScriptRegisterMetaType() function. In this way, you
+  can preserve the precise typing in your C++ declarations, while
+  still allowing pointers to your custom objects to flow seamlessly
+  between C++ and scripts. Example:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 43
+
+  \section1 Function Objects and Native Functions
+
+  In Qt Script, functions are first-class values; they are objects that
+  can have properties of their own, just like any other type of
+  object. They can be stored in variables and passed as arguments to
+  other functions. Knowing how function calls in Qt Script behave is
+  useful when you want to define and use your own script functions.
+  This section discusses this matter, and also explains how you can
+  implement native functions; that is, Qt Script functions written in
+  C++, as opposed to functions written in the scripting language
+  itself. Even if you will be relying mostly on the dynamic QObject
+  binding that Qt Script provides, knowing about these powerful
+  concepts and techniques is important to understand what's actually
+  going on when script functions are executed.
+
+  \section2 Calling a Qt Script Function from C++
+
+  Calling a Qt Script function from C++ is achieved with the
+  QScriptValue::call() function. A typical scenario is that you evaluate a
+  script that defines a function, and at some point you want to call that
+  function from C++, perhaps passing it some arguments, and then handle the
+  result. The following script defines a Qt Script object that has a
+  toKelvin() function:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 90
+
+  The toKelvin() function takes a temperature in Kelvin as argument, and
+  returns the temperature converted to Celsius. The following snippet shows
+  how the toKelvin() function might be obtained and called from C++:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 91
+
+  If a script defines a global function, you can access the function as a
+  property of QScriptEngine::globalObject(). For example, the following script
+  defines a global function add():
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 56
+
+  C++ code might call the add() function as follows:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 92
+
+  As already mentioned, functions are just values in Qt Script; a function by
+  itself is not "tied to" a particular object. This is why you have to specify
+  a \c{this} object (the first argument to QScriptValue::call()) that the
+  function should be applied to.
+
+ If the function is supposed to act as a method (i.e. it can only be applied
+  to a certain class of objects), it is up to the function itself to check
+  that it is being called with a compatible \c{this} object.
+
+ Passing an invalid QScriptValue as the \c{this} argument to
+  QScriptValue::call() indicates that the Global Object should be used as the
+  \c{this} object; in other words, that the function should be invoked as a
+  global function.
+
+  \section2 The \c this Object
+
+  When a Qt Script function is invoked from a script, the \e{way} in which it
+  is invoked determines the \c this object when the function body is executed,
+  as the following script example illustrates:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 49
+
+  An important thing to note is that in Qt Script, unlike C++ and Java, the
+  \c this object is not part of the execution scope. This means that
+  member functions (i.e., functions that operate on \c this) must always
+  use the \c this keyword to access the object's properties. For example,
+  the following script probably doesn't do what you want:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 50
+
+  You will get a reference error saying that 'a is not defined' or, worse,
+  two totally unrelated global variables \c a and \c b will be used to
+  perform the computation, if they exist. Instead, the script should look
+  like this:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 51
+
+  Accidentally omitting the \c this keyword is a typical source of
+  error for programmers who are used to the scoping rules of C++ and Java.
+
+  \section2 Wrapping a Native Function
+
+  Qt Script provides QScriptEngine::newFunction() as a way of wrapping a
+  C++ function pointer; this enables you to implement a function in
+  C++ and add it to the script environment, so that scripts can invoke
+  your function as if it were a "normal" script function. Here is how the
+  previous \c{getProperty()} function can be written in C++:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 52
+
+  Call QScriptEngine::newFunction() to wrap the function. This will
+  produce a special type of function object that carries a pointer to
+  the C++ function internally. Once the resulting wrapper has been
+  added to the scripting environment (e.g., by setting it as a property
+  of the Global Object), scripts can call the function without having
+  to know nor care that it is, in fact, a native function.
+
+  Note that the name of the C++ function doesn't matter in the
+  scripting sense; the name by which the function is invoked by
+  scripts depends only on what you call the script object property
+  in which you store the function wrapper.
+
+  It is currently not possible to wrap member functions; i.e., methods
+  of a C++ class that require a \c this object.
+
+  \section2 The QScriptContext Object
+
+  A QScriptContext holds all the state associated with a particular
+  invocation of your function. Through the QScriptContext, you can:
+  \list
+  \i Get the arguments that were passed to the function.
+  \i Get the \c this object.
+  \i Find out whether the function was called with the \c new operator
+     (the significance of this will be explained later).
+  \i Throw a script error.
+  \i Get the function object that's being invoked.
+  \i Get the activation object (the object used to hold local variables).
+  \endlist
+
+  The following sections explain how to make use of this
+  functionality.
+
+  \section2 Processing Function Arguments
+
+  Two things are worth noting about function arguments:
+
+  \list 1
+  \o Any script function \mdash including native functions \mdash can
+  be invoked with any number of arguments. This means that it is up to
+  the function itself to check the argument count if necessary, and act
+  accordingly (e.g., throw an error if the number of arguments is
+  too large, or prepare a default value if the number is too small).
+  \o A value of any type can be supplied as an argument to any
+  function. This means that it is up to you to check the type of the
+  arguments if necessary, and act accordingly (e.g., throw an error
+  if an argument is not an object of a certain type).
+  \endlist
+
+  In summary: Qt Script does not automatically enforce any constraints on the
+  number or type of arguments involved in a function call.
+
+  \section3 Formal Parameters and the Arguments Object
+
+  A native Qt Script function is analogous to a script function that defines no
+  formal parameters and only uses the built-in \c arguments variable to
+  process its arguments. To see this, let's first consider how a
+  script would normally define an \c{add()} function that takes two
+  arguments, adds them together and returns the result:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 56
+
+  When a script function is defined with formal parameters, their
+  names can be viewed as mere aliases of properties of the \c
+  arguments object; for example, in the \c{add(a, b)} definition's
+  function body, \c a and \c arguments[0] refer to the same
+  variable. This means that the \c{add()} function can equivalently be
+  written like this:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 57
+
+  This latter form closely matches what a native implementation
+  typically looks like:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 58
+
+  \section3 Checking the Number of Arguments
+
+  Again, remember that the presence (or lack) of formal parameter
+  names in a function definition does not affect how the function
+  may be invoked; \c{add(1, 2, 3)} is allowed by the engine, as is
+  \c{add(42)}. In the case of the \c {add()} function, the function
+  really needs two arguments in order to do something useful. This
+  can be expressed by the script definition as follows:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 59
+
+  This would result in an error being thrown if a script invokes
+  \c{add()} with anything other than two arguments. The native
+  function can be modified to perform the same check:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 62
+
+  \section3 Checking the Types of Arguments
+
+  In addition to expecting a certain number of arguments, a function might
+  expect that those arguments are of certain types (e.g., that the first
+  argument is a number and that the second is a string). Such a function
+  should explicitly check the type of arguments and/or perform a conversion,
+  or throw an error if the type of an argument is incompatible.
+
+  As it is, the native implementation of \c{add()} shown above doesn't
+  have the exact same semantics as the script counterpart; this is
+  because the behavior of the Qt Script \c{+} operator depends on the
+  types of its operands (for example, if one of the operands is a string,
+  string concatenation is performed). To give the script function
+  stricter semantics (namely, that it should only add numeric
+  operands), the argument types can be tested:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 60
+
+  Then an invocation like \c{add("foo", new Array())} will
+  cause an error to be thrown.
+
+  The C++ version can call QScriptValue::isNumber() to perform similar
+  tests:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 63
+
+  A less strict script implementation might settle for performing an
+  explicit to-number conversion before applying the \c{+} operator:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 61
+
+  In a native implementation, this is equivalent to calling
+  QScriptValue::toNumber() without performing any type test first,
+  since QScriptValue::toNumber() will automatically perform a type
+  conversion if necessary.
+
+  To check if an argument is of a certain object type (class),
+  scripts can use the \c instanceof operator (e.g., \c{"arguments[0]
+  instanceof Array"} evaluates to true if the first argument is an
+  Array object); native functions can call QScriptValue::instanceOf().
+
+  To check if an argument is of a custom C++ type, you typically use
+  qscriptvalue_cast() and check if the result is valid. For object types,
+  this means casting to a pointer and checking if it is non-zero; for
+  value types, the class should have an \c{isNull()}, \c{isValid()}
+  or similar method. Alternatively, since most custom types are
+  transported in \l{QVariant}s, you can check if the script value is a
+  QVariant using QScriptValue::isVariant(), and then check if the
+  QVariant can be converted to your type using QVariant::canConvert().
+
+  \section3 Functions with Variable Numbers of Arguments
+
+  Because of the presence of the built-in \c arguments object,
+  implementing functions that take a variable number of arguments
+  is simple. In fact, as we have seen, in the technical sense \e{all}
+  Qt Script functions can be seen as variable-argument functions).
+  As an example, consider a concat() function that takes an arbitrary
+  number of arguments, converts the arguments to their string
+  representation and concatenates the results; for example,
+  \c{concat("Qt", " ", "Script ", 101)} would return "Qt Script 101".
+  A script definition of \c{concat()} might look like this:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 64
+
+  Here is an equivalent native implementation:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 65
+
+  A second use case for a variable number of arguments is to implement
+  optional arguments. Here's how a script definition typically does
+  it:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 66
+
+  And here's the native equivalent:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 67
+
+  A third use case for a variable number of arguments is to simulate
+  C++ overloads. This involves checking the number of arguments and/or
+  their type at the beginning of the function body (as already shown),
+  and acting accordingly. It might be worth thinking twice before
+  doing this, and instead favor unique function names; e.g., having
+  separate \c{processNumber(number)} and \c{processString(string)}
+  functions rather than a generic \c{process(anything)} function.
+  On the caller side, this makes it harder for scripts to accidentally
+  call the wrong overload (since they don't know or don't comprehend
+  your custom sophisticated overloading resolution rules), and on the
+  callee side, you avoid the need for potentially complex (read:
+  error-prone) checks to resolve ambiguity.
+
+  \section3 Accessing the Arguments Object
+
+  Most native functions use the QScriptContext::argument() function to
+  access function arguments. However, it is also possible to access
+  the built-in \c arguments object itself (the one referred to by the
+  \c arguments variable in script code), by calling the
+  QScriptContext::argumentsObject() function. This has three principal
+  applications:
+
+  \list
+  \o The \c arguments object can be used to easily forward a function
+     call to another function. In script code, this is what it
+     typically looks like:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 68
+
+     For example, \c{foo(10, 20, 30)} would result in the \c{foo()} function
+     executing the equivalent of \c{bar(10, 20, 30)}. This is useful if
+     you want to perform some special pre- or post-processing when
+     calling a function (e.g., to log the call to \c{bar()} without having
+     to modify the \c{bar()} function itself, like the above example), or if
+     you want to call a "base implementation" from a prototype
+     function that has the exact same "signature". In C++, the forwarding
+     function might look like this:
+
+     \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 69
+
+  \o The arguments object can serve as input to a QScriptValueIterator,
+     providing a generic way to iterate over the arguments. A debugger
+     might use this to display the arguments object in a general purpose
+     "Qt Script Object Explorer", for example.
+
+  \o The arguments object can be serialized (e.g., with JSON) and transferred
+     to another entity (e.g., a script engine running in another thread),
+     where the object can be deserialized and passed as argument to
+     another script function.
+  \endlist
+
+  \section2 Constructor Functions
+
+  Some script functions are constructors; they are expected to initialize
+  new objects. The following snippet is a small example:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 75
+
+  There is nothing special about constructor functions. In fact, any
+  script function can act as a constructor function (i.e., any function
+  can serve as the operand to \c{new}). Some functions behave differently
+  depending on whether they are called as part of a \c{new} expression
+  or not; for example, the expression \c{new Number(1)} will create a
+  Number object, whereas \c{Number("123")} will perform a type
+  conversion. Other functions, like \c{Array()}, will always create
+  and initialize a new object (e.g., \c{new Array()} and \c{Array()} have
+  the same effect).
+
+  A native Qt Script function can call the
+  QScriptContext::isCalledAsConstructor() function to determine if it
+  is being called as a constructor or as a regular function. When a
+  function is called as a constructor (i.e., it is the operand in a
+  \c{new} expression), this has two important implications:
+
+  \list
+  \i The \c this object, QScriptContext::thisObject(), contains
+     the new object to be initialized; the engine creates this
+     new object automatically before invoking your function. This means
+     that your native constructor function normally doesn't have to (and
+     shouldn't) create a new object when it is called as a
+     constructor, since the engine has already prepared a new
+     object. Instead your function should operate on the supplied
+     \c this object.
+  \i The constructor function should return an undefined value,
+     QScriptEngine::undefinedValue(), to tell the engine that the
+     \c this object should be the final result of the \c new
+     operator. Alternatively, the function can return the \c this
+     object itself.
+  \endlist
+
+  When QScriptContext::isCalledAsConstructor() returns false, how your
+  constructor handles this case depends on what behavior you desire.
+  If, like the built-in \c{Number()} function, a plain function call should
+  perform a type conversion of its argument, then you perform the conversion
+  and return the result. If, on the other hand, you want your constructor
+  to behave \e{as if it was called as a constructor} (with
+  \c{new}), you have to explicitly create a new object (that is,
+  ignore the \c this object), initialize that object, and return it.
+
+  The following example implements a constructor function that always
+  creates and initializes a new object:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 76
+
+  Given this constructor, scripts would be able to use either the
+  expression \c{new Person("Bob")} or \c{Person("Bob")} to create a
+  new \c{Person} object; both behave in the same way.
+
+  There is no equivalent way for a function defined in script
+  code to determine whether or not it was invoked as a constructor.
+
+  Note that, even though it is not considered good practice, there is
+  nothing that stops you from choosing to ignore the default
+  constructed (\c this) object when your function is called as a
+  constructor and creating your own object anyway; simply have the
+  constructor return that object. The object will "override" the
+  default object that the engine constructed (i.e., the default
+  object will simply be discarded internally).
+
+  \section2 Associating Data with a Function
+
+  Even if a function is global \mdash i.e., not associated with any particular
+  (type of) object \mdash you might still want to associate some data with it,
+  so that it becomes self-contained; for example, the function could have
+  a pointer to some C++ resource that it needs to access. If your application
+  only uses a single script engine, or the same C++ resource can/should be
+  shared among all script engines, you can simply use a static C++ variable
+  and access it from within the native Qt Script function.
+
+  In the case where a static C++ variable or singleton class is
+  not appropriate, you can call QScriptValue::setProperty() on the
+  function object, but be aware that those properties will also be
+  accessible to script code. The alternative is to use QScriptValue::setData();
+  this data is not script-accessible. The implementation can access this
+  internal data through the QScriptContext::callee() function, which
+  returns the function object being invoked. The following example
+  shows how this might be used:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 55
+
+  \section2 Native Functions as Arguments to Functions
+
+  As previously mentioned, a function object can be passed as argument
+  to another function; this is also true for native functions,
+  naturally. As an example, here's a native comparison function
+  that compares its two arguments numerically:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 53
+
+  The above function can be passed as argument to the standard
+  \c{Array.prototype.sort} function to sort an array numerically,
+  as the following C++ code illustrates:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 54
+
+  Note that, in this case, we are truly treating the native function
+  object as a value \mdash i.e., we don't store it as a property of the
+  scripting environment \mdash we simply pass it on as an "anonymous"
+  argument to another script function and then forget about it.
+
+  \section2 The Activation Object
+
+  Every Qt Script function invocation has an \e{activation object}
+  associated with it; this object is accessible through the
+  QScriptContext::activationObject() function. The activation object
+  is a script object whose properties are the local variables
+  associated with the invocation (including the arguments for which
+  the script function has a corresponding formal parameter name).
+  Thus, getting, modifying, creating and deleting local variables
+  from C++ is done using the regular QScriptValue::property() and
+  QScriptValue::setProperty() functions. The activation object itself
+  is not directly accessible from script code (but it is implicitly
+  accessed whenever a local variable is read from or written to).
+
+  For C++ code, there are two principal applications of the
+  activation object:
+
+  \list
+  \i The activation object provides a standard way to traverse the
+  variables associated with a function call, by using it as the input
+  to QScriptValueIterator. This is useful for debugging purposes.
+
+  \i The activation object can be used to prepare local variables
+  that should be available when a script is evaluated inline; this
+  can be viewed as a way of passing arguments to the script
+  itself. This technique is typically used in conjunction with
+  QScriptEngine::pushContext(), as in the following example:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 77
+
+  We create a temporary execution context, create a local variable
+  for it, evaluate the script, and finally restore the old context.
+  \endlist
+
+  \section2 Nested Functions and the Scope Chain
+
+  This is an advanced topic; feel free to skip it.
+
+  A nested function can be used to "capture" the execution context in which a
+  nested function object is created; this is typically referred to as creating
+  a \e closure. When, at some later time, the nested function is invoked, it
+  can access the variables that were created when the enclosing function was
+  invoked. This can perhaps best be illustrated through a small example:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 70
+
+  The \c{counter()} function initializes a local variable to zero,
+  and returns a nested function. The nested function increments
+  the "outer" variable and returns its new value. The variable
+  persists over function calls, as shown in the following example:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 71
+
+  The \c{counter()} function can be implemented as a native function, too
+  \mdash or rather, as a pair of native functions: One for the outer and
+  one for the inner. The definition of the outer function is as follows:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 72
+
+  The function creates a local variable and initializes it to zero.
+  Then it wraps the inner native function, and sets the scope of
+  the resulting function object to be the activation object associated
+  with this (the outer) function call. The inner function accesses
+  the "outer" activation through the scope of the callee:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 73
+
+  It is also possible to have a hybrid approach, where the outer function
+  is a native function and the inner function is defined by a script:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 74
+
+  \section2 Property Getters and Setters
+
+  A script object property can be defined in terms of a getter/setter
+  function, similar to how a Qt C++ property has read and write
+  functions associated with it. This makes it possible for a script to
+  use expressions like \c{object.x} instead of \c{object.getX()}; the
+  getter/setter function for \c{x} will implicitly be invoked
+  whenever the property is accessed. To scripts, the property looks
+  and behaves just like a regular object property.
+
+  A single Qt Script function can act as both getter and setter for
+  a property. When it is called as a getter, the argument count is 0.
+  When it is called as a setter, the argument count is 1; the argument
+  is the new value of the property. In the following example, we
+  define a native combined getter/setter that transforms the value
+  slightly:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 78
+
+  The example uses the internal data of the object to store and
+  retrieve the transformed value. Alternatively, the property
+  could be stored in another, "hidden" property of the object itself
+  (e.g., \c{__x__}). A native function is free to implement whatever
+  storage scheme it wants, as long as the external behavior of the
+  property itself is consistent (e.g., that scripts should not be able
+  to distinguish it from a regular property).
+
+  The following C++ code shows how an object property can be defined
+  in terms of the native getter/setter:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 79
+
+  When the property is accessed, like in the following script, the
+  getter/setter does its job behind the scenes:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 80
+
+  \note It is important that the setter function, not just the getter,
+  returns the value of the property; i.e., the setter should \e{not}
+  return QScriptValue::UndefinedValue. This is because the result of
+  the property assignment is the value returned by the setter, and
+  not the right-hand side expression. Also note that you normally
+  should not attempt to read the same property that the getter modifies
+  within the getter itself, since this will cause the getter to be
+  called recursively.
+
+  You can remove a property getter/setter by calling
+  QScriptValue::setProperty(), passing an invalid QScriptValue
+  as the getter/setter. Remember to specify the
+  QScriptValue::PropertyGetter/QScriptValue::PropertySetter flag(s),
+  otherwise the only thing that will happen is that the setter will be
+  invoked with an invalid QScriptValue as its argument!
+
+  Property getters and setters can be defined and installed by script
+  code as well, as in the following example:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 81
+
+  Getters and setters can only be used to implement "a priori
+  properties"; i.e., the technique can't be used to react to an access
+  to a property that the object doesn't already have. To gain total
+  control of property access in this way, you need to subclass
+  QScriptClass.
+
+  \section1 Making Use of Prototype-Based Inheritance
+
+  In ECMAScript, inheritance is based on the concept of \e{shared
+  prototype objects}; this is quite different from the class-based
+  inheritance familiar to C++ programmers. With QtScript, you can
+  associate a custom prototype object with a C++ type using
+  QScriptEngine::setDefaultPrototype(); this is the key to providing
+  a script interface to that type. Since the QtScript module is built
+  on top of Qt's meta-type system, this can be done for any C++ type.
+
+  You might be wondering when exactly you would need to use this
+  functionality in your application; isn't the automatic binding
+  provided by QScriptEngine::newQObject() enough? No, not under all
+  circumstances.
+  Firstly, not every C++ type is derived from QObject; types that
+  are not QObjects cannot be introspected through Qt's meta-object
+  system (they do not have properties, signals and slots). Secondly,
+  even if a type is QObject-derived, the functionality you want to
+  expose to scripts might not all be available, since it is unusual to
+  define every function to be a slot (and it's not always
+  possible/desirable to change the C++ API to make it so).
+
+  It is perfectly possible to solve this problem by using "conventional"
+  C++ techniques. For instance, the QRect class could effectively be
+  made scriptable by creating a QObject-based C++ wrapper class with
+  \c{x}, \c{y}, \c{width} properties and so on, which forwarded property
+  access and function calls to the wrapped value. However, as we shall
+  see, by taking advantage of the ECMAScript object model and combining
+  it with Qt's meta-object system, we can arrive at a solution that is
+  more elegant, consistent and lightweight, supported by a small API.
+
+  This section explains the underlying concepts of prototype-based
+  inheritance. Once these concepts are understood, the associated
+  practices can be applied throughout the QtScript API in order to
+  create well-behaved, consistent bindings to C++ that will fit nicely
+  into the ECMAScript universe.
+
+  When experimenting with QtScript objects and inheritance, it can be
+  helpful to use the interactive interpreter included with the
+  \l{Qt Script Examples}, located in \c{examples/script/qscript}.
+
+  \section2 Prototype Objects and Shared Properties
+
+  The purpose of a QtScript \e{prototype object} is to define
+  behavior that should be shared by a set of other QtScript
+  objects. We say that objects which share the same prototype object
+  belong to the same \e{class} (again, on the technical side this
+  should not to be confused with the class constructs of languages
+  like C++ and Java; ECMAScript has no such construct).
+
+  The basic prototype-based inheritance mechanism works as follows: Each
+  QtScript object has an internal link to another object, its
+  \e{prototype}. When a property is looked up in an object, and the
+  object itself does not have the property, the property is looked up
+  in the prototype object instead; if the prototype has the property,
+  then that property is returned. Otherwise, the property is looked up
+  in the prototype of the prototype object, and so on; this chain of
+  objects constitutes a \e{prototype chain}. The chain of prototype
+  objects is followed until the property is found or the end of the
+  chain is reached.
+
+  For example, when you create a new object by the expression \c{new
+  Object()}, the resulting object will have as its prototype the
+  standard \c{Object} prototype, \c{Object.prototype}; through this
+  prototype relation, the new object inherits a set of properties,
+  including the \c{hasOwnProperty()} function and \c{toString()}
+  function:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 27
+
+  The \c{toString()} function itself is not defined in \c{o} (since we
+  did not assign anything to \c{o.toString}), so instead the
+  \c{toString()} function in the standard \c{Object} prototype is
+  called, which returns a highly generic string representation of
+  \c{o} ("[object Object]").
+
+  Note that the properties of the prototype object are not \e{copied} to
+  the new object; only a \e{link} from the new object to the prototype
+  object is maintained. This means that changes done to the prototype
+  object will immediately be reflected in the behavior of all objects
+  that have the modified object as their prototype.
+
+  \section2 Defining Classes in a Prototype-Based Universe
+
+  In QtScript, a class is not defined explicitly; there is no
+  \c{class} keyword. Instead, you define a new class in two steps:
+
+  \list 1
+  \i Define a \e{constructor function} that will initialize new objects.
+  \i Set up a \e{prototype object} that defines the class interface, and
+     assign this object to the public \c{prototype} property of the
+     constructor function.
+  \endlist
+
+  With this arrangement, the constructor's public \c{prototype}
+  property will automatically be set as the prototype of objects created
+  by applying the \c{new} operator to your constructor function;
+  e.g., the prototype of an object created by \c{new Foo()} will be the
+  value of \c{Foo.prototype}.
+
+  Functions that don't operate on the \c this object ("static" methods)
+  are typically stored as properties of the constructor function, not
+  as properties of the prototype object. The same is true for
+  constants, such as enum values.
+
+  The following code defines a simple constructor function for a class
+  called \c{Person}:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 28
+
+  Next, you want to set up \c{Person.prototype} as your prototype
+  object; i.e., define the interface that should be common to all
+  \c{Person} objects. QtScript automatically creates a default
+  prototype object (by the expression \c{new Object()}) for every
+  script function; you can add properties to this object, or you can
+  assign your own custom object. (Generally speaking, any QtScript
+  object can act as prototype for any other object.)
+
+  Here's an example of how you might want to override the
+  \c{toString()} function that \c{Person.prototype} inherits from
+  \c{Object.prototype}, to give your \c{Person} objects a more
+  appropriate string representation:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 29
+
+  This resembles the process of reimplementing a virtual function
+  in C++. Henceforth, when the property named \c{toString} is
+  looked up in a \c{Person} object, it will be resolved in
+  \c{Person.prototype}, not in \c{Object.prototype} as before:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 30
+
+  There are also some other interesting things we can learn about a
+  \c{Person} object:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 31
+
+  The \c{hasOwnProperty()} function is not inherited from
+  \c{Person.prototype}, but rather from \c{Object.prototype}, which is
+  the prototype of \c{Person.prototype} itself; i.e., the prototype
+  chain of \c{Person} objects is \c{Person.prototype} followed by
+  \c{Object.prototype}. This prototype chain establishes a \e{class
+  hierarchy}, as demonstrated by applying the \c{instanceof} operator;
+  \c{instanceof} checks if the value of the public \c{prototype}
+  property of the constructor function on the right-hand side is
+  reached by following the prototype chain of the object on the
+  left-hand side.
+
+  When defining subclasses, there's a general pattern you can use. The
+  following example shows how one can create a subclass of \c{Person}
+  called \c{Employee}:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 32
+
+  Again, you can use the \c{instanceof} to verify that the
+  class relationship between \c{Employee} and \c{Person} has been
+  correctly established:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 33
+
+  This shows that the prototype chain of \c{Employee} objects is the
+  same as that of \c{Person} objects, but with \c{Employee.prototype}
+  added to the front of the chain.
+
+  \section2 Prototype-Based Programming with the QtScript C++ API
+
+  You can use QScriptEngine::newFunction() to wrap
+  native functions. When implementing a constructor function,
+  you also pass the prototype object as an argument to
+  QScriptEngine::newFunction().
+  You can call QScriptValue::construct() to call a constructor
+  function, and you can use QScriptValue::call() from within a
+  native constructor function if you need to call a base class
+  constructor.
+
+  The QScriptable class provides a convenient way to implement a
+  prototype object in terms of C++ slots and properties. Take a look
+  at the \l{Default Prototypes Example} to see how this is done.
+  Alternatively, the prototype functionality can be implemented in
+  terms of standalone native functions that you wrap with
+  QScriptEngine::newFunction() and set as properties of your prototype
+  object by calling QScriptValue::setProperty().
+
+  In the implementation of your prototype functions, you use
+  QScriptable::thisObject() (or QScriptContext::thisObject()) to
+  obtain a reference to the QScriptValue being operated upon; then you
+  call qscriptvalue_cast() to cast it to your C++ type, and perform
+  the relevant operations using the usual C++ API for the type.
+
+  You associate a prototype object with a C++ type by calling
+  QScriptEngine::setDefaultPrototype(). Once this mapping is
+  established, QtScript will automatically assign the correct
+  prototype when a value of such a type is wrapped in a QScriptValue;
+  either when you explicitly call QScriptEngine::toScriptValue(), or
+  when a value of such a type is returned from a C++ slot and
+  internally passed back to script code by the engine. This means you
+  \e{don't} have to implement wrapper classes if you use this
+  approach.
+
+  As an example, let's consider how the \c{Person} class from the
+  preceding section can be implemented in terms of the Qt Script API.
+  We begin with the native constructor function:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 34
+
+  Here's the native equivalent of the \c{Person.prototype.toString}
+  function we saw before:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 35
+
+  The \c{Person} class can then be initialized as follows:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 36
+
+  The implementation of the \c{Employee} subclass is similar. We
+  use QScriptValue::call() to call the super-class (Person) constructor:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 37
+
+  The \c{Employee} class can then be initialized as follows:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 38
+
+  When implementing the prototype object of a class, you may want to use
+  the QScriptable class, as it enables you to define the API of your
+  script class in terms of Qt properties, signals and slots, and
+  automatically handles value conversion between the Qt Script and C++
+  side.
+
+  \section2 Implementing Prototype Objects for Value-based Types
+
+  When implementing a prototype object for a value-based type --
+  e.g. QPointF -- the same general technique applies; you populate
+  a prototype object with functionality that should be shared
+  among instances. You then associate the prototype object with
+  the type by calling QScriptEngine::setDefaultPrototype(). This
+  ensures that when e.g. a value of the relevant type is returned
+  from a slot back to the script, the prototype link of the script
+  value will be initialized correctly.
+
+  When values of the custom type are stored in QVariants -- which Qt
+  Script does by default --, qscriptvalue_cast() enables you to safely
+  cast the script value to a pointer to the C++ type. This makes it
+  easy to do type-checking, and, for prototype functions that should
+  modify the underlying C++ value, lets you modify the actual value
+  contained in the script value (and not a copy of it).
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 39
+
+  \section2 Implementing Constructors for Value-based Types
+
+  You can implement a constructor function for a value-based type
+  by wrapping a native factory function. For example, the following
+  function implements a simple constructor for QPoint:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 44
+
+  In the above code we simplified things a bit, e.g. we didn't check
+  the argument count to decide which QPoint C++ constructor to use.
+  In your own constructors you have to do this type of resolution
+  yourself, i.e. by checking the number of arguments passed to the
+  native function, and/or by checking the type of the arguments and
+  converting the arguments to the desired type. If you detect a problem
+  with the arguments you may want to signal this by throwing a script
+  exception; see QScriptContext::throwError().
+
+  \section2 Managing Non-QObject-based Objects
+
+  For value-based types (e.g. QPoint), the C++ object will be destroyed when
+  the Qt Script object is garbage-collected, so managing the memory of the C++
+  object is not an issue. For QObjects, Qt Script provides several
+  alternatives for managing the underlying C++ object's lifetime; see the
+  \l{Controlling QObject Ownership} section. However, for polymorphic types
+  that don't inherit from QObject, and when you can't (or won't) wrap the type
+  in a QObject, you have to manage the lifetime of the C++ object yourself.
+
+  A behavior that's often reasonable when a Qt Script object wraps a C++
+  object, is that the C++ object is deleted when the Qt Script object is
+  garbage-collected; this is typically the case when the objects can be
+  constructed by scripts, as opposed to the application providing the scripts
+  with pre-made "environment" objects. A way of making the lifetime of the C++
+  object follow the lifetime of the Qt Script object is by using a shared
+  pointer class, such as QSharedPointer, to hold a pointer to your object;
+  when the Qt Script object containing the QSharedPointer is
+  garbage-collected, the underlying C++ object will be deleted if there are no
+  other references to the object.
+
+  The following snippet shows a constructor function that constructs
+  QXmlStreamReader objects that are stored using QSharedPointer:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 93
+
+  Prototype functions can use qscriptvalue_cast() to cast the \c this object
+  to the proper type:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 94
+
+  The prototype and constructor objects are set up in the usual way:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 95
+
+  Scripts can now construct QXmlStreamReader objects by calling the \c
+  XmlStreamReader constructor, and when the Qt Script object is
+  garbage-collected (or the script engine is destroyed), the QXmlStreamReader
+  object is destroyed as well.
+
+  \section1 Defining Custom Script Classes with QScriptClass
+
+  There are cases where neither the dynamic QObject binding provided
+  by QScriptEngine::newQObject() or the manual binding provided by
+  QScriptEngine::newFunction() is sufficient. For example, you might
+  want to implement a dynamic script proxy to an underlying object;
+  or you might want to implement an array-like class (i.e. that gives
+  special treatment to properties that are valid array indexes, and
+  to the property "length"). In such cases, you can subclass
+  QScriptClass to achieve the desired behavior.
+
+  QScriptClass allows you to handle all property access for a
+  (class of) script object through virtual get/set property functions.
+  Iteration of custom properties is also supported through the
+  QScriptClassPropertyIterator class; this means you can advertise
+  properties to be reported by for-in script statements and
+  QScriptValueIterator.
+
+  \section1 Error Handling and Debugging Facilities
+
+  Syntax errors in scripts will be reported as soon as a script is
+  evaluated; QScriptEngine::evaluate() will return a SyntaxError object
+  that you can convert to a string to get a description of the error.
+
+  The QScriptEngine::uncaughtExceptionBacktrace() function gives you
+  a human-readable backtrace of the last uncaught exception. In order
+  to get useful filename information in backtraces, you should pass
+  proper filenames to QScriptEngine::evaluate() when evaluating your
+  scripts.
+
+  Often an exception doesn't happen at the time the script is evaluated,
+  but at a later time when a function defined by the script is actually
+  executed. For C++ signal handlers, this is tricky; consider the case
+  where the clicked() signal of a button is connected to a script function,
+  and that script function causes a script exception when it is handling
+  the signal. Where is that script exception propagated to?
+
+  The solution is to connect to the QScriptEngine::signalHandlerException()
+  signal; this will give you notification when a signal handler causes
+  an exception, so that you can find out what happened and/or recover
+  from it.
+
+  In Qt 4.4 the QScriptEngineAgent class was introduced. QScriptEngineAgent
+  provides an interface for reporting low-level "events" in a script engine,
+  such as when a function is entered or when a new script statement is
+  reached. By subclassing QScriptEngineAgent you can be notified of these
+  events and perform some action, if you want. QScriptEngineAgent itself
+  doesn't provide any debugging-specific functionality (e.g. setting
+  breakpoints), but it is the basis of tools that do.
+
+  The QScriptEngineDebugger class introduced in Qt 4.5 provides a 
+  \l{Qt Script Debugger Manual}{Qt Script debugger} that can be embedded
+  into your application.
+
+  \section2 Redefining print()
+
+  Qt Script provides a built-in print() function that can be useful for
+  simple debugging purposes. The built-in print() function writes to
+  standard output. You can redefine the print() function (or add your
+  own function, e.g. debug() or log()) that redirects the text to
+  somewhere else. The following code shows a custom print() that adds
+  text to a QPlainTextEdit.
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 45
+
+  The following code shows how the custom print() function may be
+  initialized and used.
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 46
+
+  A pointer to the QPlainTextEdit is stored as an internal property
+  of the script function itself, so that it can be retrieved when
+  the function is called.
+
+  \section1 Using QtScript Extensions
+
+  The QScriptEngine::importExtension() function can be used to load plugins
+  into a script engine. Plugins typically add some extra functionality to
+  the engine; for example, a plugin might add full bindings for the Qt
+  Arthur painting API, so that those classes may be used from Qt Script
+  scripts. There are currently no script plugins shipped with Qt.
+
+  If you are implementing some Qt Script functionality that you want other
+  Qt application developers to be able to use, \l{Creating QtScript Extensions}
+  {developing an extension} (e.g. by subclassing QScriptExtensionPlugin) is
+  worth looking into.
+
+  \section1 Internationalization
+
+  Since Qt 4.5, Qt Script supports internationalization of scripts by building
+  on the C++ internationalization functionality (see \l{Internationalization
+  with Qt}).
+
+  \section2 Use qsTr() for All Literal Text
+
+  Wherever your script uses "quoted text" for text that will be presented to
+  the user, ensure that it is processed by the QCoreApplication::translate()
+  function. Essentially all that is necessary to achieve this is to use
+  the qsTr() script function. Example:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 82
+
+  This accounts for 99% of the user-visible strings you're likely to write.
+
+  The qsTr() function uses the basename of the script's filename (see
+  QFileInfo::baseName()) as the translation context; if the filename is not
+  unique in your project, you should use the qsTranslate() function and pass a
+  suitable context as the first argument. Example:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 83
+
+  If you need to have translatable text completely outside a function, there
+  are two functions to help: QT_TR_NOOP() and QT_TRANSLATE_NOOP(). They merely
+  mark the text for extraction by the \c lupdate utility described below.  At
+  runtime, these functions simply return the text to translate unmodified.
+
+  Example of QT_TR_NOOP():
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 84
+
+  Example of QT_TRANSLATE_NOOP():
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 85
+
+  \section2 Use String.prototype.arg() for Dynamic Text
+
+  The String.prototype.arg() function (which is modeled after QString::arg())
+  offers a simple means for substituting arguments:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 86
+
+    \section2 Produce Translations
+
+    Once you are using qsTr() and/or qsTranslate() throughout your scripts, you
+    can start producing translations of the user-visible text in your program.
+
+    The \l{Qt Linguist manual} provides further information about
+    Qt's translation tools, \e{Qt Linguist}, \c lupdate and \c
+    lrelease.
+
+    Translation of Qt Script scripts is a three-step process:
+
+    \list 1
+
+    \o Run \c lupdate to extract translatable text from the script source code
+    of the Qt application, resulting in a message file for translators (a TS
+    file). The utility recognizes qsTr(), qsTranslate() and the
+    \c{QT_TR*_NOOP()} functions described above and produces TS files
+    (usually one per language).
+
+    \o Provide translations for the source texts in the TS file, using
+    \e{Qt Linguist}. Since TS files are in XML format, you can also
+    edit them by hand.
+
+    \o Run \c lrelease to obtain a light-weight message file (a QM
+    file) from the TS file, suitable only for end use. Think of the TS
+     files as "source files", and QM files as "object files". The
+    translator edits the TS files, but the users of your application
+    only need the QM files. Both kinds of files are platform and
+    locale independent.
+
+    \endlist
+
+    Typically, you will repeat these steps for every release of your
+    application. The \c lupdate utility does its best to reuse the
+    translations from previous releases.
+
+    When running \c lupdate, you must specify the location of the script(s),
+    and the name of the TS file to produce. Examples:
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 87
+
+    will extract translatable text from \c myscript.qs and create the
+    translation file \c myscript_la.qs.
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 88
+
+    will extract translatable text from all files ending with \c{.qs} in the
+    \c scripts folder and create the translation file \c scripts_la.qs.
+
+    Alternatively, you can create a separate qmake project file that sets up
+    the \c SOURCES and \c TRANSLATIONS variables appropriately; then run
+    \c lupdate with the project file as input.
+
+    \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 89
+
+    When running \c lrelease, you must specify the name of the TS input
+    file; or, if you are using a qmake project file to manage script
+    translations, you specify the name of that file. \c lrelease will create
+    \c myscript_la.qm, the binary representation of the translation.
+
+    \section2 Apply Translations
+
+    In your application, you must use QTranslator::load() to load the
+    translation files appropriate for the user's language, and install them
+    using QCoreApplication::installTranslator(). Finally, you must call
+    QScriptEngine::installTranslatorFunctions() to make the script translation
+    functions (qsTr(), qsTranslate() and \c{QT_TR*_NOOP()}) available to scripts
+    that are subsequently evaluated by QScriptEngine::evaluate(). For scripts
+    that are using the qsTr() function, the proper filename must be passed as
+    second argument to QScriptEngine::evaluate().
+
+    \c linguist, \c lupdate and \c lrelease are installed in the \c bin
+    subdirectory of the base directory Qt is installed into. Click Help|Manual
+    in \e{Qt Linguist} to access the user's manual; it contains a tutorial
+    to get you started.
+
+    See also the \l{Hello Script Example}.
+
+  \section1 ECMAScript Compatibility
+
+  QtScript implements all the built-in classes and functions defined
+  in ECMA-262.
+
+  The Date parsing and string conversion functions are implemented using
+  QDateTime::fromString() and QDateTime::toString(), respectively.
+
+  The RegExp class is a wrapper around QRegExp. The QRegExp semantics
+  do not precisely match the semantics for regular expressions defined
+  in ECMA-262.
+
+  \section1 QtScript Extensions to ECMAScript
+
+  \list
+  \i \c{__proto__} \br
+    The prototype of an object (QScriptValue::prototype())
+    can be accessed through its \c{__proto__} property in script code.
+    This property has the QScriptValue::Undeletable flag set.
+    For example:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 40
+
+  \i \c{Object.prototype.__defineGetter__} \br
+    This function installs a
+    getter function for a property of an object. The first argument is
+    the property name, and the second is the function to call to get
+    the value of that property. When the function is invoked, the
+    \c this object will be the object whose property is accessed.
+    For example:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 41
+
+  \i \c{Object.prototype.__defineSetter__} \br
+    This function installs a
+    setter function for a property of an object. The first argument is
+    the property name, and the second is the function to call to set
+    the value of that property.  When the function is invoked, the
+    \c this object will be the object whose property is accessed.
+    For example:
+
+  \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 42
+
+  \i \c{Function.prototype.connect} \br
+    This function connects
+    a signal to a slot. Usage of this function is described in
+    the section \l{Using Signals and Slots}.
+
+  \i \c{Function.prototype.disconnect} \br
+    This function disconnects
+    a signal from a slot. Usage of this function is described in
+    the section \l{Using Signals and Slots}.
+
+  \i \c{QObject.prototype.findChild} \br
+    This function is semantically equivalent to QObject::findChild().
+
+  \i \c{QObject.prototype.findChildren} \br
+    This function is semantically equivalent to QObject::findChildren().
+
+  \i \c{QObject.prototype.toString} \br
+    This function returns a default string representation of a QObject.
+
+  \i \c{gc} \br
+    This function invokes the garbage collector.
+
+  \i \c{Error.prototype.backtrace} \br
+    This function returns a human-readable backtrace, in the form of
+    an array of strings.
+
+  \i Error objects have the following additional properties:
+    \list
+    \i \c{lineNumber}: The line number where the error occurred.
+    \i \c{fileName}: The file name where the error occurred (if a file name
+    was passed to QScriptEngine::evaluate()).
+    \i \c{stack}: An array of objects describing the stack. Each object has
+      the following properties:
+      \list
+      \i \c{functionName}: The function name, if available.
+      \i \c{fileName}: The file name, if available.
+      \i \c{lineNumber}: The line number, if available.
+      \endlist
+    \endlist
+
+  \endlist
