Hi Lv, It is a known issue of the osgviewerQt example under Linux. AFAIK, OSG's multithreading mechanism could well with QtOpenGL under Windows, but the make current operation is confused when using QGLWidget as the low-level graphics context. With Qt 4.7 and Ubuntu 10.10, the example seems to work with warnings, but still not responsible. Maybe somebody could help debug into the Qt source code to find the problem later.
