set_license_type

Sets the license for this from a list of known licenses.

If the application's license is not in the list, [property@AboutWindow:license] can be used instead. The license type will be automatically set to [enum@Gtk.License.custom] in that case.

If license_type is [enum@Gtk.License.unknown], no information will be displayed.

If license_type is different from [enum@Gtk.License.custom]. [property@AboutWindow:license] will be cleared out.

The license description will be displayed on the Legal page, below the copyright information.

[method@AboutWindow.add_legal_section] can be used to add license information for the application dependencies or other components.
