overridevirtual |
Interrupts event dispatching.
The event dispatcher will return from processEvents() as soon as possible.
Implements QAbstractEventDispatcher.
|
overridevirtual |
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
\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.

overridevirtual |
Registers notifier with the event loop.
Subclasses must implement this method to tie a socket notifier into another event loop.
Implements QAbstractEventDispatcher.
|
finaloverridevirtual |
Register a timer with the specified timerId, interval, and timerType for the given object.
Implements QAbstractEventDispatcher.
|
finaloverridevirtual |
Returns the remaining time of the timer with the given timerId.
If the timer is inactive, the returned value will be negative. If the timer is overdue, the returned value will be 0.
Implements QAbstractEventDispatcher.
|
overridevirtual |
Reimplemented from QAbstractEventDispatcher.
|
finaloverridevirtual |
Returns a list of registered timers for object. The TimerInfoV2 struct has timerId
, interval
, and timerType
members.
Implements QAbstractEventDispatcher.
|
overridevirtual |
Unregisters notifier from the event dispatcher.
Subclasses must reimplement this method to tie a socket notifier into another event loop. Reimplementations must call the base implementation.
Implements QAbstractEventDispatcher.
|
finaloverridevirtual |
Unregisters the timer with the given timerId. Returns true
if successful; otherwise returns false
.
Implements QAbstractEventDispatcher.
|
finaloverridevirtual |
Unregisters all the timers associated with the given object.
Returns true
if all timers were successfully removed; otherwise returns false
.
Implements QAbstractEventDispatcher.
|
overridevirtual |
\threadsafe
Wakes up the event loop.
\omit
On Unix and Glib event dispatchers, if the dispatcher is already awake when this function is called, it is ensured that the current iteration won't block waiting for more events, but will instead do another event loop iteration.
