Gnome::Gtk4::AppChooserButton

Gnome::Gtk4::AppChooserButton

Description

The Gnome::Gtk4::AppChooserButton lets the user select an application.

No caption

Initially, a Gnome::Gtk4::AppChooserButton selects the first application in its list, which will either be the most-recently used application or, if show-default-item is True, the default application.

The list of applications shown in a Gnome::Gtk4::AppChooserButton includes the recommended applications for the given content type. When show-default-item is set, the default application is also included. To let the user chooser other applications, you can set the show-dialog-item property, which allows to open a full Gnome::Gtk4::AppChooserDialog.

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

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

CSS nodes

Gnome::Gtk4::AppChooserButton has a single CSS node with the name “appchooserbutton”.
