Description [src]

interface Gtk.AppChooser : Gtk.Widget

GtkAppChooser is an interface for widgets which allow the user to choose an application.

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().


In order to implement AppChooser, your type must inherit from GtkWidget.
