This is necessary to use an app chooser button for selecting default apps in the control center. Also, beef up the docs for this widget family. https://bugzilla.gnome.org/show_bug.cgi?id=642706

|
* @Title: GtkAppChooser
|
|
* @Short_description: Interface implemented by widgets for choosing an application
|
|
* @See_also: #GAppInfo
|
|
*
|
|
* #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().
