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.
