Description [src]

abstract class Pango.FontMap : GObject.Object {
  parent_instance: GObject
}

Signals

Signals inherited from GObject (1)

GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Signals inherited from GListModel (1)

GListModel::items-changed

This signal is emitted whenever items were added to or removed from list. At position, removed items were removed and added items were added in their place.
