Button press event propagation

Funny. Solved it myself right after I posted this! :rofl:

The secret is to attach a gesture click to the button and set the event state of the gesture click to Gtk.EventSequenceState.CLAIMED:

    def __init__(self, *args, **kwargs):
        super().__init__(title="Gesture Example", *args, **kwargs)

        # ...

        self.button = Gtk.Button(label="Click Me")
        gesture_click = Gtk.GestureClick.new()
        gesture_click.connect("pressed", self.on_button_pressed)
        self.button.add_controller(gesture_click)

    def on_button_pressed(self, click: Gtk.GestureClick, *args, **kwargs):
        print("Button clicked!")
        click.set_state(Gtk.EventSequenceState.CLAIMED)
