SYNTAX

       void  XtGrabKey(Widget  widget,  KeyCode  keycode,  Modifiers  modifiers,   Boolean   owner_events,   int
              pointer_mode, int keyboard_mode);

       void XtUngrabKey(Widget widget, KeyCode keycode, Modifiers modifiers);

       int XtGrabKeyboard(Widget widget, Boolean owner_events, int pointer_mode, int keyboard_mode, Time time);

       void XtUngrabKeyboard(Widget widget, Time time);

       void  XtGrabButton(Widget  widget,  int  button,  Modifiers modifiers, Boolean owner_events, unsigned int
              event_mask, int pointer_mode, int keyboard_mode, Window confine_to, Cursor cursor);

       void XtUngrabButton(Widget widget, KeyCode button, Modifiers modifiers);

       int XtGrabPointer(Widget widget, Boolean owner_events, unsigned int  event_mask,  int  pointer_mode,  int
              keyboard_mode, Window confine_to, Cursor cursor, Time time);

       void XtUngrabPointer(Widget widget, Time time);

ARGUMENTS

       widget    Specifies  the  widget in whose window the grab will occur. Must be of class Core or a subclass
                 thereof.

       keycode
       modifiers
       owner_events
       pointer_mode
       keyboard_mode
       time
       button
       confine_to
       cursor    Specifies arguments to the associated Xlib function call.

DESCRIPTION

       XtGrabKey calls XGrabKey specifying the widget's window as the grab window if the widget is realized. The
       remaining arguments are exactly as for XGrabKey.  If the widget is not realized, or is later  unrealized,
       the call to XGrabKey will be performed (again) when the widget is realized and its window becomes mapped.
       In  the  future,  if  XtDispatchEvent  is called with a KeyPress event matching the specified keycode and
       modifiers (which may be AnyKey or AnyModifier, respectively) for the widget's window, the Intrinsics will
       call XtUngrabKeyboard with the timestamp from the KeyPress event if either of the following conditions is
       true:

       •  There is a modal cascade and the widget is not in the active subset of the cascade  and  the  keyboard
          was not previously grabbed, or

       •  XFilterEvent returns True.

       XtUngrabKey  calls  XUngrabKey  specifying  the  widget's  window  as  the ungrab window if the widget is
       realized. The remaining arguments are exactly  as  for  XUngrabKey.   If  the  widget  is  not  realized,
       XtUngrabKey  removes  a  deferred  XtGrabKey  request,  if  any,  for  the specified widget, keycode, and
       modifiers.

       If the specified widget is realized XtGrabKeyboard calls XGrabKeyboard specifying the widget's window  as
       the  grab  window.  The  remaining  arguments  and return value are exactly as for XGrabKeyboard.  If the
       widget is not realized, XtGrabKeyboard immediately returns GrabNotViewable.  No future ungrab is  implied
       by XtGrabKeyboard.

       XtUngrabKeyboard calls XUngrabKeyboard with the specified time.

       XtGrabButton  calls  XGrabButton  specifying  the  widget's  window  as  the grab window if the widget is
       realized. The remaining arguments are exactly as for XGrabButton.  If the widget is not realized,  or  is
       later  unrealized,  the call to XGrabButton will be performed (again) when the widget is realized and its
       window becomes mapped. In the future, if XtDispatchEvent is called with a ButtonPress event matching  the
       specified  button  and  modifiers  (which may be AnyButton or AnyModifier, respectively) for the widget's
       window, the Intrinsics will call XtUngrabPointer with the timestamp from the ButtonPress event if  either
       of the following conditions is true:

       •  There is a modal cascade and the widget is not in the active subset of the cascade and the pointer was
          not previously grabbed, or

       •  XFilterEvent returns True.

       XtUngrabButton  calls  XUngrabButton specifying the widget's window as the ungrab window if the widget is
       realized. The remaining arguments are exactly as for XUngrabButton.   If  the  widget  is  not  realized,
       XtUngrabButton  removes  a  deferred  XtGrabButton request, if any, for the specified widget, button, and
       modifiers.

       XtGrabPointer calls XGrabPointer specifying the  widget's  window  as  the  grab  window.  The  remaining
       arguments and return value are exactly as for XGrabPointer.  If the widget is not realized, XtGrabPointer
       immediately returns GrabNotViewable.  No future ungrab is implied by XtGrabPointer.

       XtUngrabPointer calls XUngrabPointer with the specified time.
