I have attached the screenshot of my application running. I have also attached the view class. Again the class was generated by KDevelop and I have modified it.
I have been looking at the example Rafa mentioned, but I still cannot find the solution to the issue I am having. I select the cube.osg file from the following location: OSG_OP_OT-1.2/Producer/Test/Trackball My application reads the file and it displays. However, what you see in my screenshot disappears and I get a full screen of the cube. I am hoping some one can tell me what I am missing. I would like the cube to be displayed in the window of the application. I am a beginner with OSG, so forgive me if this is trivial. If someone has any advice, please send it my way. Now back to the reference documentation.
