Package: gdk

GBoxed gdk:event-grab-broken

Declaration

(define-gboxed-variant-cstruct event "GdkEvent"
  (type event-type)
  (window (g:object window))
  (send-event (:boolean :int8))
            ...
            ((:grab-broken) event-grab-broken
             (keyboard :boolean)
             (implicit :boolean)
             (grab-window (g:object window)))
  ... ))

Values

type: The gdk:event-type type of the event.
window: The gdk:window object which received the event, that is the window that previously owned the grab.
send-event: True if the event was sent explicitly.
keyboard: True if a keyboard grab was broken, false if a pointer grab was broken.
implicit: True if the broken grab was implicit.
grab-window: If this event is caused by another grab in the same application, grab-window contains the new gdk:window grab window. Otherwise grab-window is nil.

Details

Generated when a pointer or keyboard grab is broken. On X11, this happens when the grab window becomes unviewable, that is, it or one of its ancestors is unmapped, or if the same application grabs the pointer or keyboard again. Note that implicit grabs, which are initiated by button presses, can also cause gdk:event-grab-broken events.
