gtk:shortcuts-shortcut-subtitle (object)

object -- a gtk:shortcuts-shortcut widget
subtitle -- a string for the subtitle for the shortcut

The accessor for the subtitle slot gets or sets the subtitle for the shortcut or gesture. This is typically used for gestures and should be a short, one-line text that describes the gesture itself. For the predefined gesture types, GTK provides a subtitle on its own. This function is deprecated since 4.18. This widget will be removed in GTK 5.
