AppLaunchContext.setIconName

Sets the icon for applications that are launched with this context.

The icon_name will be interpreted in the same way as the Icon field in desktop files. See also [gdk.app_launch_context.AppLaunchContext.setIcon].

If both icon and icon_name are set, the icon_name takes priority. If neither icon or icon_name is set, the icon is taken from either the file that is passed to launched application or from the [gio.app_info.AppInfo] for the launched application itself.
