AppChooserDialog

Deprecated since version 4.10: The application selection widgets should be implemented according to the design of each platform and/or application requiring them.

class AppChooserDialog(*args, **kwargs)

Superclasses: Dialog, Window, Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, AppChooser, Buildable, ConstraintTarget, Native, Root, ShortcutManager

GtkAppChooserDialog shows a GtkAppChooserWidget inside a GtkDialog.

Note that GtkAppChooserDialog does not have any interesting methods of its own. Instead, you should get the embedded GtkAppChooserWidget using get_widget and call its methods if the generic AppChooser interface is not sufficient for your needs.

To set the heading that is shown above the GtkAppChooserWidget, use set_heading.
