Appendix A. GTK Signals

As GTK is an object oriented widget set, it has a hierarchy of inheritance. This inheritance mechanism applies for signals. Therefore, you should refer to the widget hierarchy tree when using the signals listed in this section.

A.1. GObj

A.1.1. GObj.gtkobj

method destroy : callback:(unit -> unit) -> GtkSignal.id

A.1.2. GObj.widget

widget_signals is same as the above gtkobj_signals.
