I am going to port (i.e. rewrite) an application I have previously written under sunview. It is a program to manipulate colour raster images (which come over a socket from another program). The appearance of the image (colour map, zoom, scroll, etc) depends on cursor positioning, button presses, and toggle positions. I have the Nutshell Xlib books. That stuff seems to be fairly straightforward. My questions involve the widgets (I really, really don't want to roll them myself). Which widgets should I use? The HP widgets appear to be well documented, but it looks like they don't run under the R3 intrinsics yet (is this still true)? The Athena widgets documentation seems to be more opaque, and there doesn't seem to be a toggle (I suppose you could fake it with buttons without too much work). Since this code may run on several different types of machines availability under the vendor's various X is also a concern I guess. Also, if someone can point me to a code I can study that does (preferably fairly simple) graphics stuff in a canvas with attached scrollbars and buttons/toggles I'd be grateful. Since these are probably hopelessly stupid questions, please respond by email. I will forward replies to interested parties or summarize to the list if there is enough interest. If you point me at a code let me know if I can send it to other interested people or if I should keep it under wraps. Thank you. -- Brian Glendenning - Radio astronomy, University of Toronto brian@radio.astro.utoronto.ca uunet!utai!radio!brian glendenn@utorphys.bitnet
