/**
|
|
* GtkAppChooser:
|
|
*
|
|
* `GtkAppChooser` is an interface for widgets which allow the user to
|
|
* choose an application.
|
|
*
|
|
* The main objects that implement this interface are
|
|
* [class@Gtk.AppChooserWidget],
|
|
* [class@Gtk.AppChooserDialog] and [class@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 `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 [method@Gtk.AppChooser.get_app_info].
