The QJSValue class provides functions for converting - the result to various C++ types (e.g. QJSValue::toString() - and QJSValue::toNumber()). - - The following code snippet shows how a script function can be - defined and then invoked from C++ using QJSValue::call(): - - \snippet doc/src/snippets/code/src_script_qjsengine.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_qjsengine.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_qjsengine.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. - - \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(). - Calling clearExceptions() will cause any uncaught exceptions to be - cleared. - - \snippet doc/src/snippets/code/src_script_qjsengine.cpp 4 - - \section1 Script Object Creation - - Use newObject() to create a JavaScript object; this is the - C++ equivalent of the script statement \c{new Object()}. You can use - the object-specific functionality in QJSValue to manipulate the - script object (e.g. QJSValue::setProperty()). Similarly, use - newArray() to create a JavaScript array 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.

Additionally, built-in - support is provided for Qt/C++ types such as QVariant and QObject. - - For the object-based types (including Date and RegExp), use the - newT() functions in QJSEngine (e.g. QJSEngine::newObject()) - to create a QJSValue of the desired type. For the primitive types, - use one of the QJSValue 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 - QJSValue to another type. You can also use the generic - QJSValue_cast() function. - - Object values have zero or more properties which are themselves - QJSValues. 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_qjsvalue.cpp 0 - - If you want to iterate over the properties of a script object, use - the QJSValueIterator class. - - Object values have an internal \c{prototype} property, which can be - accessed with prototype() and setPrototype(). - - Function objects (objects for which isCallable()) returns true) can - be invoked by calling call(). Constructor functions can be used to - construct new objects by calling callAsConstructor(). - - Use equals() or strictlyEquals() to compare a QJSValue to another. - - Note that a QJSValue for which isObject() is true only carries a - reference to an actual object; copying the QJSValue 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 QJSValueIterator in C++. - - \sa QJSEngine, QJSValueIterator -*/ - -/*!

Here's how to iterate over - all the properties of a QJSValue: - - \snippet doc/src/snippets/code/src_script_qjsvalueiterator.cpp 0 - - The next() advances the iterator. The name() and value() - functions return the name and value of the last item that was - jumped over. - - Note that QJSValueIterator only iterates over the QJSValue's - own properties; i.e. it does not follow the prototype chain. You can - use a loop like this to follow the prototype chain: - - \snippet doc/src/snippets/code/src_script_qjsvalueiterator.cpp 1 - - Note that QJSValueIterator will not automatically skip over - properties that have the QJSValue::SkipInEnumeration flag set; - that flag only affects iteration in script code. If you want, you - can skip over such properties with code like the following: - - \snippet doc/src/snippets/code/src_script_qjsvalueiterator.cpp 2 - - \sa QJSValue::property() -*/ - -/*! - Constructs an iterator for traversing \a object.
