Is connect_switch_page activated before or after tab switch?

Seems this method activated before Notebook page get switched

self.widget.connect_switch_page({
    |notebook, _, page_number| {
        println!("Current:{:?}", notebook.current_page()); // previous
        println!("New:{}", page_number); // currently selected
    }
});

so when I’m calling another method inside this function, it still return old page_number for get_current_page.

in gtkmm it has another behavior or maybe in rust the issue with shared pointer.

how can I detect the event, when Notebook tab already switched so?

Seems connect_page_notify method catch the event I want:

But not sure which event exactly :grinning:
