Keeping ClutterActor at the lowest level

Question

I am working on a Gnome shell extension. I have an actor which I add on uiGroup as

Main.uiGroup.add_actor( my_actor );

I also tried

Main.layoutManager.addChrome( my_actor );

as well with many options.

How can I get it sticked to the most back on window stack?

Thanks,

Answer 1

I have tried many ways of doing that and it seems impossible. Instead, I developed an application called keep_below() method in GTK.
