Functions

◆ processEvents()

bool QPAEventDispatcherGlib::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.
