Hello Ivan,


What is the difference betwen  the AdapterWidget and QOSGWidget.

I found one to be the subclass of GLWidget and the other is QWidget.

Which one is better ?

Any explanation?


Regards
Sajjad

Hi Sajjad,
The warnigs are because I'm rendering in a QWidget out of the paint event.
These warnings doesn't appear if you render in a QGLWidget, but the
CompositeViewer framework with multiple OSG views in different widgets and
multi-threaded does no render properly (at least for me [Crying or Very sad]
)

Recently I moved to Qt 4.5.0 and I had a new problem with undesired repaint
event when the OSG widget lost the focus. For example when a modal dialog is
shown, my QWidget embbeding the osg::View is repainted with the background
color and the content are removed until the osg widget recovers the focus
and is repainted again.
I solved this problem using QWidget::setUpdatesEnabled(false) but still I
have the problem of the warnings.

I think is not the same situation than yours because you are extending from
AdapterWidget, but tell if you discover something ;)

Regards,
Iván
