struct Gtk::Gesture::CancelSignal

Overview

Emitted whenever a sequence is cancelled.

This usually happens on active touches when Gtk::EventController#reset is called on @gesture (manually, due to grabs...), or the individual @sequence was claimed by parent widgets' controllers (see Gtk::Gesture#sequence_state=).

@gesture must forget everything about @sequence as in response to this signal.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/gesture.cr
