Hey Eric,
Thanks for replay to me :).
actually sorry i use them in the code, but it seem i miss to write them
anyway.. here is the code i use currently:
Code:
//if the context was created then attach to our viewer
if(graphicsContext)
{
viewer->getCamera()->setGraphicsContext(graphicsContext);
//viewer->getCamera()->setViewport(new osg::Viewport(0, 0,
traits->width, traits->height));
}
osg::setNotifyLevel(osg::DEBUG_FP);
root = new osg::MatrixTransform();
osg::Geode* geode = new osg::Geode();
osg::ShapeDrawable* drawable = new osg::ShapeDrawable( new
osg::Box(osg::Vec3(0,1,1),1));
drawable->setColor(osg::Vec4(1.0f,0.0f,1.0f,0.5f));
drawable->getOrCreateStateSet();
geode->addDrawable(drawable);
root->addChild(geode);*/
viewer->setSceneData(root.get());
viewer->setCameraManipulator(new osgGA::TrackballManipulator);
viewer->realize();
yes i use realize and setCameraManipulator
...
Thank you!

its very simple project that "should" show box on the screen , but the problem
it is not showing else the background.. and search i found that there is a
shader compiling errors in open scene graph :S. i fix it. and still nothing
appear else the background... note i wrote a test that just change the
background color to see if the problem is from opengles linking or something
like.. and its work correctly..
