For example, when the script code + + \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 0 + + is evaluated, a QScriptContext will be created, and the context will + carry the arguments as QScriptValues; in this particular case, the + arguments will be one QScriptValue containing the number 20.5, a second + QScriptValue containing the string \c{"hello"}, and a third QScriptValue + containing a Qt Script object. + + Use argumentCount() to get the number of arguments passed to the + function, and argument() to get an argument at a certain index. The + argumentsObject() function returns a Qt Script array object + containing all the arguments; you can use the QScriptValueIterator + to iterate over its elements, or pass the array on as arguments to + another script function using QScriptValue::call(). + + Use thisObject() to get the `this' object associated with the function call, + and setThisObject() to set the `this' object.

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.

Note that after scriptUnload() has been called, the + QScriptEngine may reuse the relevant script ID for new scripts + (i.e. as argument to a subsequent call to scriptLoad()). + + Evaluating the following script will result in scriptUnload() + being called immediately after evaluation has completed: + + \snippet doc/src/snippets/code/src_script_qscriptengineagent.cpp 0 + + Evaluating the following script will \b{not} result in a call to + scriptUnload() when evaluation has completed: + + \snippet doc/src/snippets/code/src_script_qscriptengineagent.cpp 1 + + The script isn't unloaded because it defines a function (\c{cube}) + that remains in the script environment after evaluation has + completed.

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.

QScriptable augments this functionality by giving your C++ - members access to the Qt Script environment they are invoked in; - conceptually, it is similar to QObject::sender(). - - By subclassing QScriptable, you get the following functions in your - class: thisObject(), argumentCount(), argument(), context() and - engine(). With these functions, you have full access to the Qt - Script environment from the slots and property access functions of - your class, when they are invoked from script code. - - For example, you can throw a Qt Script exception from a slot; - manipulate the `this' object associated with the function call; - inspect the arguments stored in the QScriptContext to know the - "real" arguments passed to the function from script code; and call - script functions from your slot. - - A typical use case of QScriptable is to implement prototype objects - for custom C++ types. You define the scriptable interface of your - custom type in a QScriptable subclass using properties and slots; - then you wrap an instance of your class using - QScriptEngine::newQObject(), and finally pass the result to - QScriptEngine::setDefaultPrototype(). See the \l{Default Prototypes Example} - to see how this can be done. - - The following is what subclassing QScriptable typically looks - like: - - \snippet doc/src/snippets/code/src_script_qscriptable.cpp 0 - - The only difference from regular QObject subclassing is that you - also inherit from QScriptable. - - In the implementation of your slots, you can then use the functions - inherited from QScriptable: - - \snippet doc/src/snippets/code/src_script_qscriptable.cpp 1 - - \sa {Default Prototypes Example}, QScriptEngine::newFunction() -*/ - -/*! - \internal -*/ -QScriptable::QScriptable() - : d_ptr(new QScriptablePrivate()) -{ - d_ptr->q_ptr = this; -} - -/*! - \internal -*/ -QScriptable::~QScriptable() -{ - delete d_ptr; - d_ptr = 0; -} - -/*! - Returns a pointer to the QScriptEngine associated with the current - Qt function call, or 0 if the Qt function was not invoked from - script code. -*/ -QScriptEngine *QScriptable::engine() const -{ - Q_D(const QScriptable); - return d->engine; -} - -/*! - Returns a pointer to the QScriptContext associated with the current - Qt function call, or 0 if the Qt function was not invoked from - script code. -*/ -QScriptContext *QScriptable::context() const -{ - if (QScriptEngine *e = engine()) - return e->currentContext(); - - return 0; -} - -/*! - Returns the `this' object associated with the current Qt function - call, or an invalid QScriptValue if the Qt function was not invoked - from script code. -*/ - -QScriptValue QScriptable::thisObject() const -{ - if (QScriptContext *c = context()) - return c->thisObject(); - - return QScriptValue(); -} - -/*! - Returns the number of arguments passed to the function in this - invocation, or -1 if the Qt function was not invoked from script - code. - - \sa argument() -*/ -int QScriptable::argumentCount() const -{ - if (QScriptContext *c = context()) - return c->argumentCount(); - - return -1; -} - -/*! - Returns the function argument at the given \a index, or an invalid - QScriptValue if the Qt function was not invoked from script code. - - \sa argumentCount() -*/ -QScriptValue QScriptable::argument(int index) const -{ - if (QScriptContext *c = context()) - return c->argument(index); - - return QScriptValue(); -} - -#endif // QT_NO_SCRIPT -#endif // QT_NO_QOBJECT - -QT_END_NAMESPACE diff --git a/src/script/qscriptable.h b/src/script/qscriptable.h deleted file mode 100644 index f990db2..0000000 --- a/src/script/qscriptable.h +++ /dev/null @@ -1,89 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2009 Nokia Corporation and/or its subsidiary(-ies). -** Contact: Qt Software Information (qt-info@nokia.com) -** -** This file is part of the QtScript module of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:LGPL$ -** No Commercial Usage -** This file contains pre-release code and may not be distributed. -** You may use this file in accordance with the terms and conditions -** contained in the either Technology Preview License Agreement or the -** Beta Release License Agreement. -** -** GNU Lesser General Public License Usage -** Alternatively, this file may be used under the terms of the GNU Lesser -** General Public License version 2.1 as published by the Free Software -** Foundation and appearing in the file LICENSE.LGPL included in the -** packaging of this file.

Such objects are created by calling - QScriptEngine::newObject(), passing a pointer to the QScriptClass as - argument. - - By subclassing QScriptClass, you can define precisely how access to - properties of the objects that use your class is handled. This - enables a fully dynamic handling of properties, e.g. it's more - powerful than QScriptEngine::newQObject(). For example, you can use - QScriptClass to implement array-type objects (i.e. objects that - handle the \c{length} property, and properties whose names are valid - array indexes, in a special way), or to implement a "live" - (runtime-defined) proxy to an underlying object. - - If you just need to handle access to a set of properties that are - known at the time an object is created (i.e. "semi-statically"), you - might consider using QScriptValue::setProperty() to define - getter/setter functions for the relevant properties, rather than - subclassing QScriptClass. - - Reimplement queryProperty() to specify which properties are handled - in a custom way by your script class (i.e. should be - \bold{delegated} to the QScriptClass), and which properties should - be handled just like normal Qt Script object properties. - - Reimplement property() and setProperty() to perform the actual - access (read or write) to the properties that your class - handles. Additionally, you can reimplement propertyFlags() to - specify custom flags for your properties. - - Reimplement newIterator() to provide an iterator for objects of your - custom class. This is only necessary if objects of your class can - have custom properties that you want to be reported when an object - is used together with the QScriptValueIterator class, or when an - object is used in a for-in enumeration statement in a script. - - When implementing custom classes of objects, you typically use - QScriptValue::setData() to store instance-specific data as part of - object initialization; the data won't be accessible from scripts - directly, but you can access it in e.g. your reimplementations of - property() and setProperty() (by calling QScriptValue::data()) to - perform custom processing. - - Reimplement prototype() to provide a custom prototype object for - your script class. - - Reimplement supportsExtension() and extension() if your custom - script class supports one or more of the extensions specified by the - Extension enum. - - \sa QScriptClassPropertyIterator, QScriptEngine::newObject(), {Custom Script Class Example} -*/ - -/*! - \enum QScriptClass::Extension - - This enum specifies the possible extensions to a QScriptClass. - - \value Callable Instances of this class can be called as functions. - - \value HasInstance Instances of this class implement [[HasInstance]]. - - \sa extension() -*/ - -/*! - \enum QScriptClass::QueryFlag - - This enum describes flags that are used to query a QScriptClass - regarding how access to a property should be handled. - - \value HandlesReadAccess The QScriptClass handles read access to this property. - \value HandlesWriteAccess The QScriptClass handles write access to this property. - - \sa queryProperty() -*/ - -class QScriptCustomClassData : public QScriptClassData -{ -public: - QScriptCustomClassData(QScriptClass *klass);

You typically want to access this - information when you're writing a native (C++) function (see - QScriptEngine::newFunction()) that will be called from script - code. For example, when the script code - - \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 0 - - is evaluated, a QScriptContext will be created, and the context will - carry the arguments as QScriptValues; in this particular case, the - arguments will be one QScriptValue containing the number 20.5, a second - QScriptValue containing the string \c{"hello"}, and a third QScriptValue - containing a Qt Script object. - - Use argumentCount() to get the number of arguments passed to the - function, and argument() to get an argument at a certain index. The - argumentsObject() function returns a Qt Script array object - containing all the arguments; you can use the QScriptValueIterator - to iterate over its elements, or pass the array on as arguments to - another script function using QScriptValue::call(). - - Use thisObject() to get the `this' object associated with the function call, - and setThisObject() to set the `this' object. If you are implementing a - native "instance method", you typically fetch the thisObject() and access - one or more of its properties: - - \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 1 - - Use isCalledAsConstructor() to determine if the function was called - as a constructor (e.g. \c{"new foo()"} (as constructor) or just - \c{"foo()"}). When a function is called as a constructor, the - thisObject() contains the newly constructed object that the function - is expected to initialize. - - Use throwValue() or throwError() to throw an exception. - - Use callee() to obtain the QScriptValue that represents the function being - called. This can for example be used to call the function recursively. - - Use parentContext() to get a pointer to the context that precedes - this context in the activation stack. This is mostly useful for - debugging purposes (e.g. when constructing some form of backtrace). - - The activationObject() function returns the object that is used to - hold the local variables associated with this function call. You can - replace the activation object by calling setActivationObject(). A - typical usage of these functions is when you want script code to be - evaluated in the context of the parent context, e.g. to implement an - include() function: - - \snippet doc/src/snippets/code/src_script_qscriptcontext.cpp 2 - - Use backtrace() to get a human-readable backtrace associated with - this context. This can be useful for debugging purposes when - implementing native functions. The toString() function provides a - string representation of the context.

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.

The engine assigns each - script an ID, which is available as one of the arguments to - scriptLoad(); subsequently, other event handlers can use the ID to - identify a particular script. One common usage of scriptLoad() is - to retain the script text, filename and base line number (the - original input to QScriptEngine::evaluate()), so that other event - handlers can e.g. map a line number to the corresponding line of - text. - - scriptUnload() is called when the QScriptEngine has no further use - for a script; the QScriptEngineAgent may at this point safely - discard any resources associated with the script (such as the - script text). Note that after scriptUnload() has been called, the - QScriptEngine may reuse the relevant script ID for new scripts - (i.e. as argument to a subsequent call to scriptLoad()). - - Evaluating the following script will result in scriptUnload() - being called immediately after evaluation has completed: - - \snippet doc/src/snippets/code/src_script_qscriptengineagent.cpp 0 - - Evaluating the following script will \b{not} result in a call to - scriptUnload() when evaluation has completed: - - \snippet doc/src/snippets/code/src_script_qscriptengineagent.cpp 1 - - The script isn't unloaded because it defines a function (\c{cube}) - that remains in the script environment after evaluation has - completed. If a subsequent script removed the \c{cube} function - (e.g. by setting it to \c{null}), scriptUnload() would be called - when the function is garbage collected. In general terms, a script - isn't unloaded until the engine has determined that none of its - contents is referenced. - - To process script function calls and returns, reimplement the - functionEntry() and functionExit() functions. functionEntry() is - called when a script function is about to be executed; - functionExit() is called when a script function is about to return, - either normally or due to an exception. - - To process individual script statements, reimplement - positionChange(). positionChange() is called each time the engine is - about to execute a new statement of a script, and thus offers the - finest level of script monitoring. - - To process exceptions, reimplement exceptionThrow() and - exceptionCatch(). exceptionThrow() is called when a script exception - is thrown, before it has been handled. exceptionCatch() is called - when an exception handler is present, and execution is about to be - resumed at the handler code. - - \sa QScriptEngine::setAgent(), QScriptContextInfo -*/ - -/*! - \enum QScriptEngineAgent::Extension - - This enum specifies the possible extensions to a QScriptEngineAgent. - - \value DebuggerInvocationRequest The agent handles \c{debugger} script statements. - - \sa extension() -*/ - -QScriptEngineAgentPrivate::QScriptEngineAgentPrivate() - : engine(0), q_ptr(0) -{ -} - -QScriptEngineAgentPrivate::~QScriptEngineAgentPrivate() -{ - QScriptEnginePrivate *eng_p = QScriptEnginePrivate::get(engine); - eng_p->agentDeleted(q_ptr); -} - -/*! - Constructs a QScriptEngineAgent object for the given \a engine. - - The engine takes ownership of the agent. - - Call QScriptEngine::setAgent() to make this agent the active - agent. -*/ -QScriptEngineAgent::QScriptEngineAgent(QScriptEngine *engine) - : d_ptr(new QScriptEngineAgentPrivate) -{ - d_ptr->q_ptr = this; - d_ptr->engine = engine; -} - -/*! - \internal -*/ -QScriptEngineAgent::QScriptEngineAgent(QScriptEngineAgentPrivate &dd, QScriptEngine *engine) - : d_ptr(&dd) -{ - d_ptr->q_ptr = this; - d_ptr->engine = engine; -} - -/*! - Destroys this QScriptEngineAgent. -*/ -QScriptEngineAgent::~QScriptEngineAgent() -{ - delete d_ptr; - d_ptr = 0; -} - -/*! - - This function is called when the engine has parsed a script and has - associated it with the given \a id.

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.

After construction, the iterator is located at the very - beginning of the sequence of properties. Here's how to iterate over - all the properties of a QScriptValue: - - \snippet doc/src/snippets/code/src_script_qscriptvalueiterator.cpp 0 - - The next() advances the iterator. The name(), value() and flags() - functions return the name, value and flags of the last item that was - jumped over. - - If you want to remove properties as you iterate over the - QScriptValue, use remove(). If you want to modify the value of a - property, use setValue(). - - Note that QScriptValueIterator only iterates over the QScriptValue'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_qscriptvalueiterator.cpp 1 - - Note that QScriptValueIterator will not automatically skip over - properties that have the QScriptValue::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_qscriptvalueiterator.cpp 2 - - \sa QScriptValue::property() -*/ - -/*! - \internal -*/ -QScriptValueIteratorPrivate::QScriptValueIteratorPrivate() - : q_ptr(0), it(0) -{ -} - -/*! - \internal -*/ -QScriptValueIteratorPrivate::~QScriptValueIteratorPrivate() -{ - delete it; -} - -/*! - Constructs an iterator for traversing \a object.
