Gtk.AccelGroup::accel-changed

function callback(accel_group, keyval:Number, modifier:Gdk.ModifierType, accel_closure:GObject.Closure, ):void;

The accel-changed signal is emitted when an entry is added to or removed from the accel group.

Widgets like Gtk.AccelLabel which display an associated accelerator should connect to this signal, and rebuild their visual representation if the accel_closure is theirs.

accel_group: instance of Gtk.AccelGroup that is emitting the signal
keyval: the accelerator keyval
modifier: the modifier combination of the accelerator
accel_closure: the GObject.Closure of the accelerator
