How to change cursor to hand when hover button?

I use gtk-rs v0.6.2 and v4_8 feature ...

You would have to use a https://gtk-rs.org/gtk4-rs/stable/latest/docs/gtk4/struct.EventControllerMotion.html and then call https://gtk-rs.org/gtk4-rs/stable/latest/docs/gtk4/prelude/trait.WidgetExt.html#tymethod.set_cursor on the widget.

Some pseudo code to help

let controller = gtk::EventControllerMotion::new();
controller.connect_enter(|controller, _, _| {
    let widget = controller.widget().unwrap();
    // See https://gtk-rs.org/gtk4-rs/stable/latest/docs/gdk4/struct.Cursor.html#method.from_name
    let cursor = gdk::Cursor::from_name("help", None::<&gdk::Cursor>);
    widget.set_cursor(Some(&cursor));
});
controller.connect_leave(|controller| {
    let widget = controller.widget().unwrap();
    widget.set_cursor(None::<&gdk::Cursor>);
});

widget.add_controller(controller);
