OpenGL child windows (bug 2398, fixed!)

[Roderick Colenbrander]

Hi,

Thanks to Chris his recent child window work, there is now support for OpenGL child windows in Wine. For the exact details read bug 2398 or Chris his patches. In short the patches use XComposite were possible and else X pixmaps. Not all drivers support both properly yet but for compiz/aiglx purposes most drivers are adding the needed support.

I would say test the stuff and report problems.

Actually the example you gave is one of the corner cases which I don't think are expected to work (windows has lots of issues in that area too). You should try apps like Google Earth, Google Sketchup, professional CAD apps and so on. Those should work fine.

This seems to be due to a couple factors. First, since the GL window is the 
top-level window, it draws to it directly so it doesn't get clipped. Second, 
CreateWindow for the GL window is missing the WS_CLIPCHILDREN flag. If I 
force offscreen rendering and add the flag, the demo works.

What can probably be done is to check if the window has the flags set to clip 
from children, and don't allow onscreen rendering with that. Then the only 
question is why Windows is assuming WS_CLIPCHILDREN for the window (maybe 
CreateWindow implies it while CreateWindowEx doesn't?).

I have tested Lightwave 6 (didn't yet tested new version but I guess it will 
work too), GoogleEarth (for Windows) and Maxwell Studio 1.5.1 (for Windows) 
and everything works fine! I'm using Debian Etch and KDE 3.5.5 and my X 
server has XComposite extension enabled but I don't actually use it in KDE so 
I'm not sure does this have any useful effect or not.
	It's so great that this bug is finally fixed! I really tired to port big 
hacky patches to new versions of WINE... Now everything works out-of-the box!
	Great work!

I tested git version with solidworks, and now it's worse than  with
previous chris patch : 

- quite slow, just like with composite patch
- highlighted lines offset, just like with composite patch
- GLXbaddrawable crash when opening multiple windows, regression from
the composite patch, that allows multiple windows 

It looks like all the previous issues are cumulated !

maybe I missed something ?

What display drivers are you using? In general Nvidia's drivers are the only ones which work 100% correct. I also heard good results from the latest intel drivers (git).

proprietary nvidia up-to-date from ubuntu feisty, exactly the same that for .45 
or .45+patch tests. I switched off compiz, but it doesn't change anything

I just check sources from git, and ./configure && make depend && make && sudo 
make install, and then run /usr/local/bin/wine sldworks.exe

My libs are correct, as i can build ubuntu wine packages.
