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 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 diff --git a/examples/examples.pro b/examples/examples.pro index e6cece9dac..c334fd5363 100644 --- a/examples/examples.pro +++ b/examples/examples.pro @@ -22,10 +22,10 @@ SUBDIRS = \ widgets \ uitools \ xml \ - script \ multitouch \ gestures +contains(QT_CONFIG, script): SUBDIRS += script contains(QT_CONFIG, multimedia):!static: SUBDIRS += multimedia contains(QT_CONFIG, phonon):!static: SUBDIRS += phonon contains(QT_CONFIG, webkit): SUBDIRS += webkit diff --git a/examples/script/calculator/main.cpp b/examples/script/calculator/main.cpp index d85d0ae2aa..2930a972a8 100644 --- a/examples/script/calculator/main.cpp +++ b/examples/script/calculator/main.cpp @@ -60,7 +60,7 @@ int main(int argc, char **argv) QScriptEngine engine; //!

The QScriptValue class provides functions for converting + the result to various C++ types (e.g. QScriptValue::toString() + and QScriptValue::toNumber()). + + The following code snippet shows how a script function can be + defined and then invoked from C++ using QScriptValue::call(): + + \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 1 + + As can be seen from the above snippets, a script is provided to the + engine in the form of a string. One common way of loading scripts is + by reading the contents of a file and passing it to evaluate(): + + \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 2 + + Here we pass the name of the file as the second argument to + evaluate(). This does not affect evaluation in any way; the second + argument is a general-purpose string that is used to identify the + script for debugging purposes (for example, our filename will now + show up in any uncaughtExceptionBacktrace() involving the script). + + \section1 Engine Configuration + + The globalObject() function returns the \bold {Global Object} + associated with the script engine. Properties of the Global Object + are accessible from any script code (i.e. they are global + variables). Typically, before evaluating "user" scripts, you will + want to configure a script engine by adding one or more properties + to the Global Object: + + \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 3 + + Adding custom properties to the scripting environment is one of the + standard means of providing a scripting API that is specific to your + application. Usually these custom properties are objects created by + the newQObject() or newObject() functions, or constructor functions + created by newFunction(). + + \section1 Script Exceptions + + evaluate() can throw a script exception (e.g. due to a syntax + error); in that case, the return value is the value that was thrown + (typically an \c{Error} object). You can check whether the + evaluation caused an exception by calling hasUncaughtException(). In + that case, you can call toString() on the error object to obtain an + error message. The current uncaught exception is also available + through uncaughtException(). You can obtain a human-readable + backtrace of the exception with uncaughtExceptionBacktrace(). + Calling clearExceptions() will cause any uncaught exceptions to be + cleared. + + \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 4 + + The checkSyntax() function can be used to determine whether code can be + usefully passed to evaluate(). + + \section1 Script Object Creation + + Use newObject() to create a standard Qt Script object; this is the + C++ equivalent of the script statement \c{new Object()}. You can use + the object-specific functionality in QScriptValue to manipulate the + script object (e.g. QScriptValue::setProperty()). Similarly, use + newArray() to create a Qt Script array object. Use newDate() to + create a \c{Date} object, and newRegExp() to create a \c{RegExp} + object. + + \section1 QObject Integration + + Use newQObject() to wrap a QObject (or subclass) + pointer. newQObject() returns a proxy script object; properties, + children, and signals and slots of the QObject are available as + properties of the proxy object. No binding code is needed because it + is done dynamically using the Qt meta object system. + + \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 5 + + Use qScriptConnect() to connect a C++ signal to a script function; + this is the Qt Script equivalent of QObject::connect(). When a + script function is invoked in response to a C++ signal, it can cause + a script exception; you can connect to the signalHandlerException() + signal to catch such an exception. + + Use newQMetaObject() to wrap a QMetaObject; this gives you a "script + representation" of a QObject-based class. newQMetaObject() returns a + proxy script object; enum values of the class are available as + properties of the proxy object. You can also specify a function that + will be used to construct objects of the class (e.g. when the + constructor is invoked from a script). For classes that have a + "standard" Qt constructor, Qt Script can provide a default script + constructor for you; see scriptValueFromQMetaObject(). + + See the \l{QtScript} documentation for more information on + the QObject integration. + + \section1 Support for Custom C++ Types + + Use newVariant() to wrap a QVariant. This can be used to store + values of custom (non-QObject) C++ types that have been registered + with the Qt meta-type system. To make such types scriptable, you + typically associate a prototype (delegate) object with the C++ type + by calling setDefaultPrototype(); the prototype object defines the + scripting API for the C++ type. Unlike the QObject integration, + there is no automatic binding possible here; i.e. you have to create + the scripting API yourself, for example by using the QScriptable + class. + + Use fromScriptValue() to cast from a QScriptValue to another type, + and toScriptValue() to create a QScriptValue from another value. + You can specify how the conversion of C++ types is to be performed + with qScriptRegisterMetaType() and qScriptRegisterSequenceMetaType(). + By default, Qt Script will use QVariant to store values of custom + types. + + \section1 Importing Extensions + + Use importExtension() to import plugin-based extensions into the + engine. Call availableExtensions() to obtain a list naming all the + available extensions, and importedExtensions() to obtain a list + naming only those extensions that have been imported. + + Call pushContext() to open up a new variable scope, and popContext() + to close the current scope. This is useful if you are implementing + an extension that evaluates script code containing temporary + variable definitions (e.g. \c{var foo = 123;}) that are safe to + discard when evaluation has completed. + + \section1 Native Functions + + Use newFunction() to wrap native (C++) functions, including + constructors for your own custom types, so that these can be invoked + from script code. Such functions must have the signature + QScriptEngine::FunctionSignature. You may then pass the function as + argument to newFunction(). Here is an example of a function that + returns the sum of its first two arguments: + + \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 6 + + To expose this function to script code, you can set it as a property + of the Global Object: + + \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 7 + + Once this is done, script code can call your function in the exact + same manner as a "normal" script function: + + \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 8 + + \section1 Long-running Scripts + + If you need to evaluate possibly long-running scripts from the main + (GUI) thread, you should first call setProcessEventsInterval() to + make sure that the GUI stays responsive. You can abort a currently + running script by calling abortEvaluation(). You can determine + whether an engine is currently running a script by calling + isEvaluating(). + + \section1 Core Debugging/Tracing Facilities + + Since Qt 4.4, you can be notified of events pertaining to script + execution (e.g. script function calls and statement execution) + through the QScriptEngineAgent interface; see the setAgent() + function. This can be used to implement debugging and profiling of a + QScriptEngine. + + \sa QScriptValue, QScriptContext, QScriptEngineAgent + +*/ + +/*! + \enum QScriptEngine::ValueOwnership + + This enum specifies the ownership when wrapping a C++ value, e.g. by using newQObject(). + + \value QtOwnership The standard Qt ownership rules apply, i.e. the associated object will never be explicitly deleted by the script engine.

Additionally, Qt Script + has built-in support for QVariant, QObject and QMetaObject. + + For the object-based types (including Date and RegExp), use the + newT() functions in QScriptEngine (e.g. QScriptEngine::newObject()) + to create a QScriptValue of the desired type. For the primitive types, + use one of the QScriptValue constructor overloads. + + The methods named isT() (e.g. isBool(), isUndefined()) can be + used to test if a value is of a certain type. The methods named + toT() (e.g. toBool(), toString()) can be used to convert a + QScriptValue to another type. You can also use the generic + qscriptvalue_cast() function. + + Object values have zero or more properties which are themselves + QScriptValues. Use setProperty() to set a property of an object, and + call property() to retrieve the value of a property. + + \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 0 + + Each property can have a set of attributes; these are specified as + the third (optional) argument to setProperty(). The attributes of a + property can be queried by calling the propertyFlags() function. The + following code snippet creates a property that cannot be modified by + script code: + + \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 1 + + If you want to iterate over the properties of a script object, use + the QScriptValueIterator class. + + Object values have an internal \c{prototype} property, which can be + accessed with prototype() and setPrototype(). Properties added to a + prototype are shared by all objects having that prototype; this is + referred to as prototype-based inheritance. In practice, it means + that (by default) the property() function will automatically attempt + to look up look the property in the prototype() (and in the + prototype of the prototype(), and so on), if the object itself does + not have the requested property. Note that this prototype-based + lookup is not performed by setProperty(); setProperty() will always + create the property in the script object itself. For more + information, see the \l{QtScript} documentation. + + Function objects (objects for which isFunction() returns true) can + be invoked by calling call(). Constructor functions can be used to + construct new objects by calling construct(). + + Use equals(), strictlyEquals() and lessThan() to compare a QScriptValue + to another. + + Object values can have custom data associated with them; see the + setData() and data() functions. By default, this data is not + accessible to scripts; it can be used to store any data you want to + associate with the script object. Typically this is used by custom + class objects (see QScriptClass) to store a C++ type that contains + the "native" object data. + + Note that a QScriptValue for which isObject() is true only carries a + reference to an actual object; copying the QScriptValue will only + copy the object reference, not the object itself.

The QScriptValue class provides functions for converting - the result to various C++ types (e.g. QScriptValue::toString() - and QScriptValue::toNumber()). - - The following code snippet shows how a script function can be - defined and then invoked from C++ using QScriptValue::call(): - - \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 1 - - As can be seen from the above snippets, a script is provided to the - engine in the form of a string. One common way of loading scripts is - by reading the contents of a file and passing it to evaluate(): - - \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 2 - - Here we pass the name of the file as the second argument to - evaluate(). This does not affect evaluation in any way; the second - argument is a general-purpose string that is used to identify the - script for debugging purposes (for example, our filename will now - show up in any uncaughtExceptionBacktrace() involving the script). - - \section1 Engine Configuration - - The globalObject() function returns the \bold {Global Object} - associated with the script engine. Properties of the Global Object - are accessible from any script code (i.e. they are global - variables). Typically, before evaluating "user" scripts, you will - want to configure a script engine by adding one or more properties - to the Global Object: - - \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 3 - - Adding custom properties to the scripting environment is one of the - standard means of providing a scripting API that is specific to your - application. Usually these custom properties are objects created by - the newQObject() or newObject() functions, or constructor functions - created by newFunction(). - - \section1 Script Exceptions - - evaluate() can throw a script exception (e.g. due to a syntax - error); in that case, the return value is the value that was thrown - (typically an \c{Error} object). You can check whether the - evaluation caused an exception by calling hasUncaughtException(). In - that case, you can call toString() on the error object to obtain an - error message. The current uncaught exception is also available - through uncaughtException(). You can obtain a human-readable - backtrace of the exception with uncaughtExceptionBacktrace(). - Calling clearExceptions() will cause any uncaught exceptions to be - cleared. - - \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 4 - - The checkSyntax() function can be used to determine whether code can be - usefully passed to evaluate(). - - \section1 Script Object Creation - - Use newObject() to create a standard Qt Script object; this is the - C++ equivalent of the script statement \c{new Object()}. You can use - the object-specific functionality in QScriptValue to manipulate the - script object (e.g. QScriptValue::setProperty()). Similarly, use - newArray() to create a Qt Script array object. Use newDate() to - create a \c{Date} object, and newRegExp() to create a \c{RegExp} - object. - - \section1 QObject Integration - - Use newQObject() to wrap a QObject (or subclass) - pointer. newQObject() returns a proxy script object; properties, - children, and signals and slots of the QObject are available as - properties of the proxy object. No binding code is needed because it - is done dynamically using the Qt meta object system. - - \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 5 - - Use qScriptConnect() to connect a C++ signal to a script function; - this is the Qt Script equivalent of QObject::connect(). When a - script function is invoked in response to a C++ signal, it can cause - a script exception; you can connect to the signalHandlerException() - signal to catch such an exception. - - Use newQMetaObject() to wrap a QMetaObject; this gives you a "script - representation" of a QObject-based class. newQMetaObject() returns a - proxy script object; enum values of the class are available as - properties of the proxy object. You can also specify a function that - will be used to construct objects of the class (e.g. when the - constructor is invoked from a script). For classes that have a - "standard" Qt constructor, Qt Script can provide a default script - constructor for you; see scriptValueFromQMetaObject(). - - See the \l{QtScript} documentation for more information on - the QObject integration. - - \section1 Support for Custom C++ Types - - Use newVariant() to wrap a QVariant. This can be used to store - values of custom (non-QObject) C++ types that have been registered - with the Qt meta-type system. To make such types scriptable, you - typically associate a prototype (delegate) object with the C++ type - by calling setDefaultPrototype(); the prototype object defines the - scripting API for the C++ type. Unlike the QObject integration, - there is no automatic binding possible here; i.e. you have to create - the scripting API yourself, for example by using the QScriptable - class. - - Use fromScriptValue() to cast from a QScriptValue to another type, - and toScriptValue() to create a QScriptValue from another value. - You can specify how the conversion of C++ types is to be performed - with qScriptRegisterMetaType() and qScriptRegisterSequenceMetaType(). - By default, Qt Script will use QVariant to store values of custom - types. - - \section1 Importing Extensions - - Use importExtension() to import plugin-based extensions into the - engine. Call availableExtensions() to obtain a list naming all the - available extensions, and importedExtensions() to obtain a list - naming only those extensions that have been imported. - - Call pushContext() to open up a new variable scope, and popContext() - to close the current scope. This is useful if you are implementing - an extension that evaluates script code containing temporary - variable definitions (e.g. \c{var foo = 123;}) that are safe to - discard when evaluation has completed. - - \section1 Native Functions - - Use newFunction() to wrap native (C++) functions, including - constructors for your own custom types, so that these can be invoked - from script code. Such functions must have the signature - QScriptEngine::FunctionSignature. You may then pass the function as - argument to newFunction(). Here is an example of a function that - returns the sum of its first two arguments: - - \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 6 - - To expose this function to script code, you can set it as a property - of the Global Object: - - \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 7 - - Once this is done, script code can call your function in the exact - same manner as a "normal" script function: - - \snippet doc/src/snippets/code/src_script_qscriptengine.cpp 8 - - \section1 Long-running Scripts - - If you need to evaluate possibly long-running scripts from the main - (GUI) thread, you should first call setProcessEventsInterval() to - make sure that the GUI stays responsive. You can abort a currently - running script by calling abortEvaluation(). You can determine - whether an engine is currently running a script by calling - isEvaluating(). - - \section1 Core Debugging/Tracing Facilities - - Since Qt 4.4, you can be notified of events pertaining to script - execution (e.g. script function calls and statement execution) - through the QScriptEngineAgent interface; see the setAgent() - function. This can be used to implement debugging and profiling of a - QScriptEngine. - - \sa QScriptValue, QScriptContext, QScriptEngineAgent - -*/ - -/*! - \enum QScriptEngine::ValueOwnership - - This enum specifies the ownership when wrapping a C++ value, e.g. by using newQObject(). - - \value QtOwnership The standard Qt ownership rules apply, i.e. the associated object will never be explicitly deleted by the script engine.

Additionally, Qt Script - has built-in support for QVariant, QObject and QMetaObject. - - For the object-based types (including Date and RegExp), use the - newT() functions in QScriptEngine (e.g. QScriptEngine::newObject()) - to create a QScriptValue of the desired type. For the primitive types, - use one of the QScriptValue constructor overloads. - - The methods named isT() (e.g. isBool(), isUndefined()) can be - used to test if a value is of a certain type. The methods named - toT() (e.g. toBool(), toString()) can be used to convert a - QScriptValue to another type. You can also use the generic - qscriptvalue_cast() function. - - Object values have zero or more properties which are themselves - QScriptValues. Use setProperty() to set a property of an object, and - call property() to retrieve the value of a property. - - \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 0 - - Each property can have a set of attributes; these are specified as - the third (optional) argument to setProperty(). The attributes of a - property can be queried by calling the propertyFlags() function. The - following code snippet creates a property that cannot be modified by - script code: - - \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 1 - - If you want to iterate over the properties of a script object, use - the QScriptValueIterator class. - - Object values have an internal \c{prototype} property, which can be - accessed with prototype() and setPrototype(). Properties added to a - prototype are shared by all objects having that prototype; this is - referred to as prototype-based inheritance. In practice, it means - that (by default) the property() function will automatically attempt - to look up look the property in the prototype() (and in the - prototype of the prototype(), and so on), if the object itself does - not have the requested property. Note that this prototype-based - lookup is not performed by setProperty(); setProperty() will always - create the property in the script object itself. For more - information, see the \l{QtScript} documentation. - - Function objects (objects for which isFunction() returns true) can - be invoked by calling call(). Constructor functions can be used to - construct new objects by calling construct(). - - Use equals(), strictlyEquals() and lessThan() to compare a QScriptValue - to another. - - Object values can have custom data associated with them; see the - setData() and data() functions. By default, this data is not - accessible to scripts; it can be used to store any data you want to - associate with the script object. Typically this is used by custom - class objects (see QScriptClass) to store a C++ type that contains - the "native" object data. - - Note that a QScriptValue for which isObject() is true only carries a - reference to an actual object; copying the QScriptValue will only - copy the object reference, not the object itself. If you want to - clone an object (i.e. copy an object's properties to another - object), you can do so with the help of a \c{for-in} statement in - script code, or QScriptValueIterator in C++. - - \sa QScriptEngine, QScriptValueIterator -*/ - -/*! - \enum QScriptValue::SpecialValue - - This enum is used to specify a single-valued type. - - \value UndefinedValue An undefined value. - - \value NullValue A null value. -*/ - -/*! - \enum QScriptValue::PropertyFlag - - This enum describes the attributes of a property. - - \value ReadOnly The property is read-only.
