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

•   returns

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

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

calls with the specified time.
