  • Method Details

    • onEnter

      void onEnter()
      Emitted whenever the focus enters into the widget or one
      of its descendents.

      Note that this means you may not get an ::enter signal
      even though the widget becomes the focus location, in
      certain cases (such as when the focus moves from a descendent
      of the widget to the widget itself). If you are interested
      in these cases, you can monitor the
      [property@Gtk.EventControllerFocus:is-focus]
      property for changes.
