</picture>

Initially, a `GtkAppChooserButton` selects the first application
in its list, which will either be the most-recently used application
or, if [property@Gtk.AppChooserButton: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
[property@Gtk.AppChooserButton:show-default-item] is set, the default
application is also included. To let the user chooser other applications,
you can set the [property@Gtk.AppChooserButton:show-dialog-item] property,
which allows to open a full [class@Gtk.AppChooserDialog].

It is possible to add custom items to the list, using
[method@Gtk.AppChooserButton.append_custom_item]. These items cause
the [signal@Gtk.AppChooserButton::custom-item-activated] signal to be
emitted when they are selected.

To track changes in the selected application, use the
[signal@Gtk.AppChooserButton::changed] signal.

## CSS nodes

`GtkAppChooserButton` has a single CSS node with the name “appchooserbutton”.
