The AButton class is designed as full a substitute to ALabel. The GtkButton attribute 'button_' is initialized with a label. This label can the be referenced by the subsequent inheritors of AButton instead of the GtkLabel attribute 'label_' of ALabel. For convenience a GtkLabel* 'label_' attribute is added to AButton. If the button cannot be clicked it is disabled, effectively acting like its label predecessor. GtkButton seems to catch one-click mouse events regardless of the flags set on it. Therefore, 'signal_pressed' is connected to a function creating a fake GdkEventButton* and calling 'handleToggle' (for details on this possible bug in GTK see: https://stackoverflow.com/questions/45334911 ) In accordance with other GtkButtons (i.e. the sway/workspace ones) set_relief(Gtk::RELIEF_NONE) is called on the 'button_' instance.
