/** A button to launch an application chooser dialog.
 *
 * This widget lets the user select an application. See the AppChooser base class API.
 *
 * Initially, an AppChooserButton selects the first application
 * in its list, which will either be the most-recently used application
 * or, if property_show_default_item() is <tt>true</tt>, the
 * default application.
 *
 * The list of applications shown in an AppChooserButton includes
 * the recommended applications for the given content type. When
 * property_show_default_item() is set, the default application
 * is also included. To let the user choose other applications,
 * you can set property_show_dialog_item(),
 * which allows to open a full AppChooserDialog.
 *
 * It is possible to add custom items to the list, using append_custom_item().
 * These items cause signal_custom_item_activated() to be
 * emitted when they are selected.
 *
 * To track changes in the selected application, use ComboBox::signal_changed().
 *
 * The AppChooserButton widget looks like this:
 * @image html appchooserbutton1.png

 * @ingroup Widgets
