* SECTION:gtkappchooser
* @Title: GtkAppChooser
* @Short_description: Interface implemented by widgets for choosing an application
+ * @See_also: #GAppInfo
*
* #GtkAppChooser is an interface that can be implemented by widgets which
* allow the user to choose an application (typically for the purpose of
* opening a file). The main objects that implement this interface are
* #GtkAppChooserWidget, #GtkAppChooserDialog and #GtkAppChooserButton.
+ *
+ * Applications are represented by GIO #GAppInfo objects here.
+ * GIO has a concept of recommended and fallback applications for a
+ * given content type. Recommended applications are those that claim
+ * to handle the content type itself, while fallback also includes
+ * applications that handle a more generic content type. GIO also
+ * knows the default and last-used application for a given content
+ * type. The #GtkAppChooserWidget provides detailed control over
+ * whether the shown list of applications should include default,
+ * recommended or fallback applications.
+ *
+ * To obtain the application that has been selected in a #GtkAppChooser,
+ * use gtk_app_chooser_get_app_info().
*/
#include "config.h"
*
* 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.
