AppChooserProtocol

public protocol AppChooserProtocol : WidgetProtocol

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().

The AppChooserProtocol protocol exposes the methods and properties of an underlying GtkAppChooser instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see AppChooser. Alternatively, use AppChooserRef as a lighweight, unowned reference if you already have an instance you just want to use.
