[Documentation / Example] Could a specific example for events be added? about gtk4pythontutorial HOT 1 OPEN

You can see I touch on the subject in this section: https://github.com/Taiko2k/GTK4PythonTutorial#input-handling-in-our-drawing-area

There are different controllers such as EventControllerKey, EventControllerMotion, or GestureClick. You create one and add it to whatever widget using .add_controller(controller).

So for mouse click

        controller = Gtk.GestureClick.new()
        controller.connect("pressed", self.click)  # could be "released"
        controller.set_button(0)  # 0 for all buttons
        self.add_controller(controller)  # here self is window but could be any widget
    def click(self,  gesture, data, x, y):
        button = gesture.get_current_button()
        print(button)

What I didn't mention which may be useful was if you want to override a widgets normal behavior such as keyboard input on a text entry box, you can do controller.set_propagation_phase(Gtk.PropagationPhase.CAPTURE) then in the callback functions, return True or False as to if you handled the event.
