How to create layout like iGoogle portal

[Victor]

Hi all,

Just want to know how to create the stacked window like iGoogle which with each child-window has min/max button, and any of them can be drag & drop to relocate to another place. A panel will be divided into several column and for each column it can host many sub-windows with vertical alignment. I think it must be built on GWT widght but just can not find it.
Any ideas are appreciated.

Regards,
Victor

I'm sorry, but I don't know how the iGoogle portal is created.

I would recommend asking general GWT questions in Google's GWT forum.
