Detailed Description

\inmodule QtCore

The QAbstractEventDispatcher class provides an interface to manage Qt's event queue.

An event dispatcher receives events from the window system and other sources. It then sends them to the QCoreApplication or QApplication instance for processing and delivery. QAbstractEventDispatcher provides fine-grained control over event delivery.

For simple control of event processing use QCoreApplication::processEvents().

For finer control of the application's event loop, call instance() and call functions on the QAbstractEventDispatcher object that is returned. If you want to use your own instance of QAbstractEventDispatcher or of a QAbstractEventDispatcher subclass, you must install it with QCoreApplication::setEventDispatcher() or QThread::setEventDispatcher() before a default event dispatcher has been installed.

The main event loop is started by calling QCoreApplication::exec(), and stopped by calling QCoreApplication::exit(). Local event loops can be created using QEventLoop.

Programs that perform long operations can call processEvents() with a bitwise OR combination of various QEventLoop::ProcessEventsFlag values to control which events should be delivered.

QAbstractEventDispatcher also allows the integration of an external event loop with the Qt event loop.

Here is the caller graph for this function:

◆ filterNativeEvent()

bool QAbstractEventDispatcher::filterNativeEvent	(	const QByteArray &	eventType,
		void *	message,
		qintptr *	result
	)

Sends message through the event filters that were set by installNativeEventFilter().

This function returns true as soon as an event filter returns true, and false otherwise to indicate that the processing of the event should continue.

Subclasses of QAbstractEventDispatcher must call this function for all messages received from the system to ensure compatibility with any extensions that may be used in the application. The type of event eventType is specific to the platform plugin chosen at run-time, and can be used to cast message to the right type. The result pointer is only used on Windows, and corresponds to the LRESULT pointer.

Note that the type of message is platform dependent. See QAbstractNativeEventFilter for details.

The timer's interval.

\variable QAbstractEventDispatcher::TimerInfo::timerType

The timer's type

See also: Qt::TimerType

Installs an event filter filterObj for all native events received by the application.

The event filter filterObj receives events via its \l {QAbstractNativeEventFilter::}{nativeEventFilter()} function, which is called for all events received by all threads.

The \l {QAbstractNativeEventFilter::}{nativeEventFilter()} function should return true if the event should be filtered, (in this case, stopped). It should return false to allow normal Qt processing to continue: the native event can then be translated into a QEvent and handled by the standard Qt \l{QEvent} {event} filtering, e.g. QObject::installEventFilter().

If multiple event filters are installed, the filter that was installed last is activated first.

Note: The filter function set here receives native messages, that is, MSG or XEvent structs.

For maximum portability, you should always try to use QEvent objects and QObject::installEventFilter() whenever possible.

Here is the caller graph for this function:

◆ interrupt()

void QAbstractEventDispatcher::interrupt ( )

pure virtual

Interrupts event dispatching.

The event dispatcher will return from processEvents() as soon as possible.

Implemented in QCocoaEventDispatcher, QEventDispatcherGlib, QEventDispatcherUNIX, QEventDispatcherCoreFoundation, QEventDispatcherWasm, and QEventDispatcherWin32.

◆ processEvents()

bool QAbstractEventDispatcher::processEvents ( QEventLoop::ProcessEventsFlags flags )

pure virtual

Processes pending events that match flags until there are no more events to process.

Returns true if an event was processed; otherwise returns false.

This function is especially useful if you have a long running operation, and want to show its progress without allowing user input by using the QEventLoop::ExcludeUserInputEvents flag.

If the QEventLoop::WaitForMoreEvents flag is set in flags, the behavior of this function is as follows:

\list

If events are available, this function returns after processing them.

If no events are available, this function will wait until more are available and return after processing newly available events.

\endlist

If the QEventLoop::WaitForMoreEvents flag is not set in flags, and no events are available, this function will return immediately.

{Note:} This function does not process events continuously; it returns after all available events are processed.

Implemented in QCocoaEventDispatcher, QEventDispatcherCoreFoundation, QEventDispatcherGlib, QEventDispatcherUNIX, QEventDispatcherWasm, QEventDispatcherWin32, QPAEventDispatcherGlib, QUnixEventDispatcherQPA, QWindowsGuiEventDispatcher, QAndroidEventDispatcher, QIOSJumpingEventDispatcher, and QXcbUnixEventDispatcher.

◆ registeredTimers()

QList< TimerInfo > QAbstractEventDispatcher::registeredTimers ( QObject * object ) const

pure virtual

Returns a list of registered timers for object.

The TimerInfo struct has timerId, interval, and timerType members.

See also: Qt::TimerType

Implemented in QCocoaEventDispatcher, QEventDispatcherGlib, QEventDispatcherUNIX, QEventDispatcherCoreFoundation, QEventDispatcherWasm, and QEventDispatcherWin32.

Referenced by QObject::event().

Here is the caller graph for this function:

◆ registerSocketNotifier()

void QAbstractEventDispatcher::registerSocketNotifier ( QSocketNotifier * notifier )

pure virtual

Registers notifier with the event loop.

Note: processEvents() only processes events queued before the function is called. Events that are posted while the function runs will be queued until a later round of event processing. This only applies to posted Qt events. For timers and system level events, the situation is unknown.

Subclasses must implement this method to tie a socket notifier into another event loop.

Implemented in QCocoaEventDispatcher, QEventDispatcherUNIX, QEventDispatcherCoreFoundation, QEventDispatcherWasm, QEventDispatcherWin32, and QEventDispatcherGlib.

◆ registerTimer() [1/2]

void QAbstractEventDispatcher::registerTimer	(	int	timerId,
		qint64	interval,
		Qt::TimerType	timerType,
		QObject *	object
	)

pure virtual

Register a timer with the specified timerId, interval, and timerType for the given object.

Implemented in QCocoaEventDispatcher, QEventDispatcherGlib, QEventDispatcherUNIX, QEventDispatcherCoreFoundation, QEventDispatcherWasm, and QEventDispatcherWin32.

◆ registerTimer() [2/2]

int QAbstractEventDispatcher::registerTimer	(	qint64	interval,
		Qt::TimerType	timerType,

◆ removeNativeEventFilter()

void QAbstractEventDispatcher::removeNativeEventFilter ( QAbstractNativeEventFilter * filter )

Removes the event filter filter from this object.

The request is ignored if such an event filter has not been installed.

All event filters for this object are automatically removed when this object is destroyed.

It is always safe to remove an event filter, even during event filter filter activation (that is, even from within the \l {QAbstractNativeEventFilter::}{nativeEventFilter()} function).
