[ngl-devel] Big changes in NUI

[Sebastien Metrot]

Hi all!

I've pretty silent in the last 4 months or so, mainly for personal 
reasons. I started to work on nui again some weeks ago and I almost 
finished a BIG change in the way the widget tree works:

nuiMainWindow have been broken down in 3 classes:
   nuiTopLevel
   nuiWindowManager (+ nuiWindowDecoration)
   nuiMainWindow (no inherits from nuiTopLevel and nglWindow).

nuiWindow have changed a lot (a lot of code moved from it to 
nuiWindowDecoration and nuiWindowManager).

The nuiWindowManager class is the one that now handles all the 
overlapped window behaviour. This is where we will be able to implement 
docking, mosaic, tilling, etc. in the future. nuiWindowDecoration is a 
way to have the window decoration separated from the nuiWindow which now 
represents only the client area (removed most of the hacks that where 
needed to make it stand alone).

Of course some features have been broken in this first implementation: 
D'n'Drop is one of them (mostly because windows don't move by themselves 
anymore now).

What you need to do to adapt an existing nui application:
if you used nuiDragAndDrop: it's broken so look at the code and help me 
fix it! ;).
if you used ovelapped windows: create an nuiWindowManager as the main 
widget in your nuiMainWindow and put windows in it just as you did 
before with nuiMainWindow. Notice that nuiWindowManager is a basic 
container widget so you could actually create MDI interfaces, windows 
inside windows, etc...
if you haven't used any of these: let me know if you find some strange 
behaviours in the way you app works now, some stuff may be broken now!

These changes will go in the CVS very soon (I still have one or two 
stupid bugs to nail down...).

Have fun and let me now if there is any problem!
