module Gtk::AppChooser


Gtk::AppChooser is an interface for widgets which allow the user to choose an application.

The main objects that implement this interface are Gtk::AppChooserWidget, Gtk::AppChooserDialog and Gtk::AppChooserButton.

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 Gtk::AppChooserWidget 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 Gtk::AppChooser, use Gtk::AppChooser#app_info.
