/**
 * The #GtkAppChooserButton is a widget that lets the user select
 * an application. It implements the #GtkAppChooser interface.
 * 
 * Initially, a #GtkAppChooserButton selects the first application
 * in its list, which will either be the most-recently used application
 * or, if #GtkAppChooserButton:show-default-item is %TRUE, the
 * default application.
 * 
 * The list of applications shown in a #GtkAppChooserButton includes
 * the recommended applications for the given content type. When
 * #GtkAppChooserButton:show-default-item is set, the default application
 * is also included. To let the user chooser other applications,
 * you can set the #GtkAppChooserButton:show-dialog-item property,
 * which allows to open a full #GtkAppChooserDialog.
 * 
 * It is possible to add custom items to the list, using
 * gtk_app_chooser_button_append_custom_item(). These items cause
 * the #GtkAppChooserButton::custom-item-activated signal to be
 * emitted when they are selected.
 * 
 * To track changes in the selected application, use the
 * #GtkComboBox::changed signal.
