Module: Gtk::AppChooser

Defined in:
(unknown)

Overview

Gtk::AppChooser 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 Gtk::AppChooserWidget, #GtkAppChooserDialog and #GtkAppChooserButton.

Applications are represented by GIO GApp::Info 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_app_chooser_get_app_info().
