[osg-submissions] QT issue

[Tomas Hnilica]

Robert,

sorry for problematic post.
Attached is modified source of AdapterWidget.cpp file from osgviewerQT 
example. Original was token today from SVN - trunk. (2.3.6).
 --mdi option needs to be set to run MDI version.

Few notes:
- tested on Windows box (Win XP)
- using QT4
- I was not able to execute the example with QOSGWidget  - had same
error like described in [osg-users] "fate error using QOSGWidget in 
develop release
2.3.0" thread from Shuxing Xiao, 2008-01-08.
- problems are described in source

Cheers,
Tomas
