Class

Gtk.AppChooserButton

Description [src]

final class Gtk.AppChooserButton : Gtk.Widget {
  /* No available fields */
}

The GtkAppChooserButton lets the user select an application.

An example GtkAppChooserButton

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

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

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

CSS nodes

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