Functions

◆ flush()

void QEventDispatcherBlackberryQPA::flush ( )
virtual

Flushes the event queue.

This normally returns almost immediately. Does nothing on platforms other than X11.

Reimplemented from QEventDispatcherUNIX.

Definition at line 106 of file qeventdispatcher_blackberry_qpa.cpp.

107 {
108  if (qApp)
109  qApp->sendPostedEvents();

#define qApp

◆ hasPendingEvents()

bool QEventDispatcherBlackberryQPA::hasPendingEvents ( )
virtual

Returns true if there is an event waiting; otherwise returns false.

Reimplemented from QEventDispatcherUNIX.

Definition at line 101 of file qeventdispatcher_blackberry_qpa.cpp.

102 {
104 }
bool hasPendingEvents()
Returns true if there is an event waiting; otherwise returns false.

◆ processEvents()

bool QEventDispatcherBlackberryQPA::processEvents ( QEventLoop::ProcessEventsFlags  flags)
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; i.e. by using the QEventLoop::ExcludeUserInputEvents flag.

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

  • 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.

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.

static bool sendWindowSystemEvents(QAbstractEventDispatcher *eventDispatcher, QEventLoop::ProcessEventsFlags flags)
