Guys, It just occured to me that you may not all agree regarding the use of the GTK widget set. In fact, Konrad and Thomas (sorry if you don't like being called Tom) have used Ousterhout's Tk widget set: Konrad used Python/Tkinter in MMTK and Thomas used Tcl/Tk in BioWish and GRS. If any of you think we should reconsider our choice widget sets, please speak up. I might be willing to switch to Tk if I find the reasons compelling. In any case, I don't want anyone to walk away from the project over this. Pleeeeeeeeeeease don't go! :-) What are the pros and cons of each? This is what I think: Tk GTK ========== ============= Pro: Multiplatform Con: UNIX only for now Con: Tkinter requires Tcl Pro: Bindings to many languages are being made Con: Rather large and slow Pro: Python/GTK seems faster Con: Looks like old Motif Pro: Modern look and Theme-able Jeff -- J.W.
