The `GtkAppChooserButton` lets the user select an application.

![An example GtkAppChooserButton](appchooserbutton.png)

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:GtkAppChooserButton:custom-item-activated] signal to be emitted when they are selected.

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