How to have Mulitple Canvas

I am trying to do this but getting all sort of error form …GlContext to “Unable to enumerate pixel formats of window using wglGetPixelFormatAttribivARB: error code -1073283059”…
I want to render multiple secneGraph in seperate Canvases…that is mainScneGraph in Centre with other sceneGrpah in side windows and all Canvases respond to user events.
It would be very helpful if anyone can post code about multiple canvas…or same SceneGraph render in multiple canvas with different views …any help is much appreciated as i want a direction to think about this…
