XtProcessEvent() XtProcessEvent()
Name
XtProcessEvent - get and process one input event of a specified type.
Synopsis
void XtProcessEvent(mask)
XtInputMask mask;
Inputs
mask Specifies what types of events to process.
Availability
XtProcessEvent() has been superseded by XtAppProcessEvent().
Description
XtProcessEvent() processes one X event, alternate input source event or timer event. The mask argument specifies which types of events are
to be processed; it is the bitwise inclusive OR ( ) of any of the values XtIMXEvent, XtIMTimer, or XtIMAlternateInput, or the value XtIMAll
which specifies all three event types. XtProcessEvent() calls any registered background work procedures if there are no events available,
and blocks if there are no events and no work procedures.
Usage
XtProcessEvent() has been superseded by XtAppProcessEvent(), which performs the same function on a per-application context basis. XtPro-
cessEvent() now calls
XtAppProcessEvent() passing the default application context created by
XtInitialize(). Very few programs need multiple application contexts, and you can
continue to use XtProcessEvent() if you initialize your application with
XtInitialize(). We recommend, however, that you use XtAppInitialize(), XtAppProcessEvent(), and the other XtApp*() application context
specific functions.
See XtAppProcessEvent() for more information.
Programs rarely need this much control over the event dispatching mechanism. Most programs use XtAppMainLoop().
