/* Pickers
* #Keywords: GtkColorChooser, GtkFontChooser, GtkApplicationChooser
*
* These widgets are mainly intended for use in preference dialogs.
* They allow to select colors, fonts, directories and applications.
*
* This demo shows both the default appearance for these dialogs,
* as well as some of the customizations that are possible.
