Connect to KeyReleaseEvent signal.

The ::key-release-event signal is emitted when a key is released.

To receive this signal, the #GdkWindow associated to the widget needs to enable the #GDK_KEY_RELEASE_MASK mask.

This signal will be sent to the grab widget if there is one.

`callback`	signal callback delegate or function to connect `bool callback(gdk.event_key.EventKey event, gtk.widget.Widget widget)` `event` the #GdkEventKey which triggered this signal. (optional) `widget` the instance the signal is connected to (optional) `Returns` true to stop other handlers from being invoked for the event. false to propagate the event further.
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)
