IconTheme.lookupIcon

Looks up a named icon for a desired size and window scale, returning a GtkIconPaintable.

The icon can then be rendered by using it as a GdkPaintable, or you can get information such as the filename and size.

If the available @icon_name is not available and @fallbacks are provided, they will be tried in order.

If no matching icon is found, then a paintable that renders the "missing icon" icon is returned. If you need to do something else for missing icons you need to use [method@Gtk.IconTheme.has_icon].

Note that you probably want to listen for icon theme changes and update the icon. This is usually done by overriding the GtkWidgetClass.css-changed() function.
