       XtUngrabButton, XtGrabPointer, XtUngrabPointer - manage grabs

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.
