activateWidget

For widgets that can be “activated” (buttons, menu items, etc.), this function activates them.

The activation will emit the signal set using method@Gtk.WidgetClass.set_activate_signal during class initialization.

Activation is what happens when you press Enter on a widget during key navigation.

If you wish to handle the activation keybinding yourself, it is recommended to use method@Gtk.WidgetClass.add_shortcut with an action created with ctor@Gtk.SignalAction.new.

If @widget isn't activatable, the function returns false.
