Which Gtk container signal detects that a mouse pointer is on top of the widget?

I have a Grid container with 4 buttons. I need to catch a signal that can recognize that a mouse pointer is hovering on top of a Button. I don't want to click a button yet. I just want to detect pointer presence.

Solution

  • The signals you are looking for are enter-notify-event and leave-notify-event.
