Hi this is a small update to the new tabbed. It fixes a small issue and cleans up the code a bit. Andrea Mon Sep 24 21:34:19 CEST 2007 Andrea Rossato * Added a NewTabbed module with a new tabbed layout to test Tue Sep 25 15:37:49 CEST 2007 Andrea Rossato * NewTabbed: fixed a bug and some code formatting - Since now Operations.windows doesn't call sendMessage UnDoLayout anymore, doLayout must take care of destroying all tabs when only one window ( or none) is left on the workspace. - Some code formatting.
