/**
* 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().
