IupFlush

Processes all pending messages in the message queue.

Parameters/Return

void IupFlush(void);

Notes

When you change an attribute of a certain element, the change may not take place immediately. For this update to occur faster than usual, call IupFlush after the attribute is changed.

Important: A call to this function may cause other callbacks to be processed before it returns.

In Motif, if the X server sent an event which is not yet in the event queue, after a call to IupFlush the queue might not be empty.

On Android and iOS, drains messages currently queued on the main thread (same mechanism as IupLoopStep).
