Could GtkLayout be contained within GtkLayout??

["driverking" <driverking pchome com tw>]

Hi,

Is it possible to make outer GtkLayout contained within inner GtkLayout widget?
I need a container widget which is like the Panel component in Java.
This container widget can contain another container widget provided with its location
coordinate with respect to its parent container. 

Another question, is there any widget similar to the motif DrawingArea?
The motif DrawingArea can be both a canvas and a container, but the GtkDrawingArea
seems to be a pure canvas. If GTK+ doesn't support this widget, how can I write a widget
with such feature? 

Thanks for your time.
