xtpeekevent
XtPeekEvent() XtPeekEvent() Name XtPeekEvent - return, but do not remove the event at the head of an application's input queue. Synopsis Boolean XtPeekEvent(event_return) XEvent *event_return; Inputs event_return Returns the event information from the head event structure in the queue. Returns True if the event at the head of the queue is an X event; False if it is a timer event or an alternate input source event. Availability XtPeekEvent() has been superseded by XtAppPeekEvent(). Description XtPeekEvent() returns a copy of the X event at the head of the input queue, without removing it from the queue. If there is an X event, it returns True. If there are no X events pending, but there are timer or alternate events, XtPeekEvent() returns False. If there are no events pending, XtPeekEvent() blocks. Usage XtPeekEvent() has been superseded by XtAppPeekEvent(), which performs the same function on a per-application context basis. XtPeekEvent() now calls XtAppPeekEvent() passing the default application context created by XtInitialize(). Very few programs need multiple application contexts, and you can continue to use XtPeekEvent() if you initialize your application with XtInitialize(). We recommend, however, that you use XtAppInitialize(), XtAppPeekEvent(), and the other XtApp*() application context specific functions. See XtAppPeekEvent() for more information. Programs rarely need this much control over the event dispatching mechanism. Most programs use XtAppMainLoop(). See Also XtAppMainLoop(1), XtAppPeekEvent(1), XtAppPending(1).
