Gtk.AppChooserButton

const Gtk = imports.gi.Gtk;

let app_chooser_button = new Gtk.AppChooserButton({
    heading: value,
    show_default_item: value,
    show_dialog_item: value,
});
  

The Gtk.AppChooserButton is a widget that lets the user select an application. It implements the Gtk.AppChooser interface.

Initially, a Gtk.AppChooserButton selects the first application in its list, which will either be the most-recently used application or, if Gtk.show-default-item is true, the default application.

The list of applications shown in a Gtk.AppChooserButton includes the recommended applications for the given content type. When Gtk.show-default-item is set, the default application is also included. To let the user chooser other applications, you can set the Gtk.show-dialog-item property, which allows to open a full Gtk.AppChooserDialog.

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

To track changes in the selected application, use the Gtk.changed signal.
