Sort of. When a thread first creates a window, windows also creates the message queue for the thread. Windows messages are per thread, so only the thread which owns the window will see the messages for the window in it's event loop, so you can't have another thread process mouse events, etc. The pure gl stuff does work though, so you can draw from another thread. With windows you should really make sure only one thread actually creates windows as if you have multiple windows in different threads the only safe synchronisation primitive is MsgWaitForMultipleObjects which is a huge pain in the butt. I've had a go at doing a properly separately threaded viewer window before and even being extra careful I couldn't stop it dead locking. > > -- > This message is subject to the CSIR's copyright terms and conditions, e-mail > legal notice, and implemented Open Document Format (ODF) standard.
