.SH DESCRIPTION
.ZN XtGrabKey
calls
.ZN XGrabKey
specifying the widget's window as the grab window if the widget is
realized. The remaining arguments are exactly as for
.ZN XGrabKey .
If the widget is not realized, or is later unrealized, the call to
.ZN XGrabKey
will be performed (again) when the widget is realized and its window
becomes mapped. In the future, if
.ZN XtDispatchEvent
is called with a
.ZN KeyPress
event matching the specified keycode and modifiers (which may be
.ZN AnyKey
or
.ZN AnyModifier ,
respectively) for the widget's window, the Intrinsics will call
.ZN XtUngrabKeyboard
with the timestamp from the
.ZN KeyPress
event if either of the following conditions is true:
.IP \(bu 3
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
.IP \(bu 3
.ZN XFilterEvent
returns
.ZN True .
.LP
.ZN XtUngrabKey
calls
.ZN XUngrabKey
specifying the widget's window as the ungrab window if the widget is
realized. The remaining arguments are exactly as for
.ZN XUngrabKey .
If the widget is not realized,
.ZN XtUngrabKey
removes a deferred
.ZN XtGrabKey
request, if any, for the specified widget, keycode, and modifiers.
.LP
If the specified widget is realized
.ZN XtGrabKeyboard
calls
.ZN XGrabKeyboard
specifying the widget's window as the grab window. The remaining
arguments and return value are exactly as for
.ZN XGrabKeyboard .
If the widget is not realized,
.ZN XtGrabKeyboard
immediately returns
.ZN GrabNotViewable .
No future ungrab is implied by
.ZN XtGrabKeyboard .
.LP
.ZN XtUngrabKeyboard
calls
.ZN XUngrabKeyboard
with the specified time.
.LP
.ZN XtGrabButton
calls
.ZN XGrabButton
specifying the widget's window as the grab window if the widget is
realized. The remaining arguments are exactly as for
.ZN XGrabButton .
If the widget is not realized, or is later unrealized, the call to
.ZN XGrabButton
will be performed (again) when the widget is realized and its window
becomes mapped. In the future, if
.ZN XtDispatchEvent
is called with a
.ZN ButtonPress
event matching the specified button and modifiers (which may be
.ZN AnyButton
or
.ZN AnyModifier ,
respectively) for the widget's window, the Intrinsics will call
.ZN XtUngrabPointer
with the timestamp from the
.ZN ButtonPress
event if either of the following conditions is true:
.IP \(bu 3
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
.IP \(bu 3
.ZN XFilterEvent
returns
.ZN True .
.LP
.ZN XtUngrabButton
calls
.ZN XUngrabButton
specifying the widget's window as the ungrab window if the widget is
realized. The remaining arguments are exactly as for
.ZN XUngrabButton .
If the widget is not realized,
.ZN XtUngrabButton
removes a deferred
.ZN XtGrabButton
request, if any, for the specified widget, button, and modifiers.
.LP
.ZN XtGrabPointer
calls
.ZN XGrabPointer
specifying the widget's window as the grab window. The remaining
arguments and return value are exactly as for
.ZN XGrabPointer .
If the widget is not realized,
.ZN XtGrabPointer
immediately returns
.ZN GrabNotViewable .
No future ungrab is implied by
.ZN XtGrabPointer .
.LP
.ZN XtUngrabPointer
calls
.ZN XUngrabPointer
with the specified time.
