public bool gtk_dialogs_use_header { get; set; }
Whether builtin GTK+ dialogs such as the file chooser, the color chooser or the font chooser will use a header bar at the top to show action widgets, or an action area at the bottom.
This setting does not affect custom dialogs using GtkDialog directly, or message dialogs.
