Member Function Documentation

deadlock()

void NullEventLoop::deadlock ( )

private

exec()

void NullEventLoop::exec ( PlatformEventHandler *  eventHandler )

overridevirtual

Starts this event loop.

This function blocks until either quit is called from inside the event handler code, or an application is closed by the user (e.g. after the last window is closed, or Command+Q is pressed on Mac).

Parameters

eventHandler

Callback for event processing.

Implements PlatformEventLoop.

processMessages()

void NullEventLoop::processMessages ( PlatformEventHandler *  eventHandler, int  count = -1  )

overridevirtual

Processes the messages that are currently in the message queue, and returns. Returns immediately if there are no messages in the message queue.

Parameters

eventHandler	Callback for event processing.
count	Maximum number of messages to process, -1 means unlimited.

Implements PlatformEventLoop.

quit()

void NullEventLoop::quit ( )

overridevirtual

Tells this event loop to exit. Does nothing if the event loop is not running.

Implements PlatformEventLoop.

waitForMessages()

void NullEventLoop::waitForMessages ( )

overridevirtual

Blocks until at least one message is delivered to the queue, and returns.

Implements PlatformEventLoop.
