Hi Joel, I did a very-very simplified layout system based on top,bottom,left,right,width and height CSS attributes:
http://69.20.122.77:8880/gwt-layout/ So far SimpleLayout, HBoxLayout & VBoxLayout are implemented. Source files: http://69.20.122.77:8880/gwt-layout/org.gwt20.mosaic.demo.tbz2 The EntryPoint class for the demo is: http://pastebin.com/m27e7a4e7 Kind Regards, George.
