Commandering GTKWindow

Is there a way to easily to have child GTK applications start in a GtkWindow of the parent's application choice? Or would this require changing the Gtk libraries?

From stackoverflow

• If I understood question correctly, then you should use GtkPlug/GtkSocket for embedding one application into another.

• There is the GtkSocket::steal() function that sounds about right, but it has been deprecated. As dmitry-vk mentioned, look into the rest of the Socket/Plug pair API to figure out how it's done nowadays.
