+ * @Title: GtkAppChooserButton
+ * @Short_description: A button to launch an application chooser dialog
+ *
+ * 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.
