Hi, this is the floatinglayout I was talking about in my previous message. This is not complete: it will place the windows on the screen diagonal, and it will assign a new position to the any new window (and not to the old ones). This is just a proof of concept, if you want, to show you the possibility of using a layout modifier (WindowArranger)as a UI for moving/resizing windows. Maybe this could be considered an evidence of the lack of need of a floating layer? I'm not sure. I had some spare time, and I was willing to play with the type system, nothing more...;) andrea Fri Jan 18 20:18:34 CET 2008 Andrea Rossato <andrea.rossato@unibz.it> * Add Layout.Diagonal the start of a floating layout
