24 * @Title: GtkAppChooser
25 * @Short_description: Interface implemented by widgets for choosing an application
26 * @See_also: #GAppInfo
28 * #GtkAppChooser is an interface that can be implemented by widgets which
29 * allow the user to choose an application (typically for the purpose of
30 * opening a file). The main objects that implement this interface are
31 * #GtkAppChooserWidget, #GtkAppChooserDialog and #GtkAppChooserButton.
33 * Applications are represented by GIO #GAppInfo objects here.
34 * GIO has a concept of recommended and fallback applications for a
35 * given content type. Recommended applications are those that claim
36 * to handle the content type itself, while fallback also includes
37 * applications that handle a more generic content type. GIO also
38 * knows the default and last-used application for a given content
39 * type. The #GtkAppChooserWidget provides detailed control over
40 * whether the shown list of applications should include default,
41 * recommended or fallback applications.
43 * To obtain the application that has been selected in a #GtkAppChooser,
44 * use gtk_app_chooser_get_app_info().
