/**
* SECTION:gtkappchooserbutton
* @Title: GtkAppChooserButton
* @Short_description: A button to launch an application chooser dialog
*
* The #GtkAppChooserButton is a widget that lets the user select
* an application. It implements the #GtkAppChooser interface.
*
* 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
* #GtkComboBox::changed signal.
