Class Details¶

class Gtk.AppChooserButton(**kwargs)¶

Bases:: Gtk.ComboBox, Gtk.AppChooser
Abstract:: No
Structure:: Gtk.AppChooserButtonClass

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.AppChooserButton :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.AppChooserButton :show-default-item is set, the default application is also included. To let the user chooser other applications, you can set the Gtk.AppChooserButton :show-dialog-item property, which allows to open a full Gtk.AppChooserDialog.

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

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

classmethod new(content_type)[source]¶

Parameters:: content_type (str) – the content type to show applications for
Returns:: a newly created Gtk.AppChooserButton
Return type:: Gtk.Widget

Creates a new Gtk.AppChooserButton for applications that can handle content of the given type.

append_custom_item(name, label, icon)[source]¶

Parameters:

Clients can use the provided name as a detail for the Gtk.AppChooserButton ::custom-item-activated signal, to add a callback for the activation of a particular custom item in the list. See also Gtk.AppChooserButton.append_separator().
