Specifies additional data to be passed to the client's event handler.
Specifies the event mask for which m.
Specifies a Boolean value that indicates whether this procedure should be called or removed on the nonmaskable events (GraphicsExpose, NoExpose, SelectionClear, SelectionRequest, SelectionNotify, ClientMessage, and MappingNotify).
Specifies the procedure that is to be added or removed.
Specifies the widget for which this event handler is being registered.
Specifies when the event handler is to be called relative to other previously registered handlers.
The XtAddRawEventHandler function is similar to XtAddEventHandler except that it does not affect the widget's mask and never causes an XSelectInput for its events. Note that the widget might already have those mask bits set because of other nonraw event handlers registered on it.
The XtRemoveRawEventHandler function stops the specified procedure from receiving the specified events. Because the procedure is a raw event handler, this does not affect the widget's mask and never causes a call on XSelectInput.
XtInsertEventHandler is identical to XtAddEventHandler with the additional position argument. if position is XtListHead, the event handler is registered to that it will be called before any event handlers that were previously registered for the same widget. If position is XtListTail, the event handler is registered to be called after any previously registered event handlers. If the procedure is already registered with the same client_data value, the specified mask augments the existing mask and the procedure is repositioned in the list.
XtInsertRawEventHandler is similar to XtInsertEventHandler except that it does not modify the widget's event mask and never causes an XSelectInput for the specified events. If the procedure is already registered with the same client_data value, the specified mask augments the existing mask and the procedure is repositioned in the list.
