The class of events distributed when a frame is about to exit.
duim-frames
duim-frames
The class of events distributed when a frame is about to exit. Contrast this with <frame-exited-event>, which is passed after the frame is exited.
The default method uses frame-can-exit? to decide whether or not to exit.
If destroy-frame?: is #t, then the frame is destroyed.
