enter


Description:

public signal void enter ()

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.
