Gtk.Frame.prototype.get_label

function get_label():String {
    // Gjs wrapper for gtk_frame_get_label()
}

If the frame's label widget is a Gtk.Label, returns the text in the label widget. (The frame will have a Gtk.Label for the label widget if a non-null argument was passed to Gtk.new.)

Returns: the text in the label, or null if there was no label widget or the lable widget was not a Gtk.Label. This string is owned by GTK+ and must not be modified or freed.
