Variable: GtkAppChooserButton

const GtkAppChooserButton: "GtkAppChooserButton"

Defined in: generated/jsx.ts:13390

The GtkAppChooserButton lets the user select an application.

Initially, a GtkAppChooserButton 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 GtkAppChooserButton 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.AppChooserButton.:changed signal.
