Member Function Documentation

virtual bool Core::EventHandlerContext::is_eventhandler_thread ( ) const

pure virtual

Check whether we are running on the thread that handles the events This function is needed to avoid to post and execute things in an infinite loop.

Implemented in QtUtils::QtEventHandlerContext, and Core::DefaultEventHandlerContext.

virtual void Core::EventHandlerContext::post_and_wait_event ( EventHandle &  event )

pure virtual

Post an event onto the event handler stack. This one returns after the thread signals that the event has been executed. The function does the full hand shaking for the synchronization.

Implemented in QtUtils::QtEventHandlerContext, and Core::DefaultEventHandlerContext.

virtual void Core::EventHandlerContext::post_event ( EventHandle &  event )

pure virtual

Post an event onto the event handler stack. This one returns immediately after posting the event, and does not wait for the process to finish the event.

Implemented in QtUtils::QtEventHandlerContext, and Core::DefaultEventHandlerContext.
