Class
Gtk.AppChooserButton
Description [src]
final class Gtk.AppChooserButton : Gtk.Widget {
/* No available fields */
}The GtkAppChooserButton lets the user select an application.
Initially, a GtkAppChooserButton selects the first application
in its list, which will either be the most-recently used application
or, if GtkAppChooserButton:show-default-item is TRUE, the
default application.
The list of applications shown in a GtkAppChooserButton includes
the recommended applications for the given content type. When
GtkAppChooserButton:show-default-item is set, the default
application is also included. To let the user chooser other applications,
you can set the GtkAppChooserButton:show-dialog-item property,
which allows to open a full GtkAppChooserDialog.
It is possible to add custom items to the list, using
gtk_app_chooser_button_append_custom_item(). These items cause
the GtkAppChooserButton::custom-item-activated signal to be
emitted when they are selected.
To track changes in the selected application, use the
GtkAppChooserButton::changed signal.
