The default bit-gravity for a window is Forget. This means you get Expose events upon reconfiguring because the server considers the window contents to be ``lost.'' In your widget realize method, try setting the bit-gravity attribute to NorthWest, and see if that gets rid of the Expose events. The server is free to consider bit-gravity as a hint, and therefore ignore it, but the sample servers distributed by MIT should actually use the information. - Joel McCormack (decwrl!joel, joel@decwrl.dec.com)
