I'm writing a program which will display and allow manipulation of heirarchical graphs, and I'm using Xview. I was reading in vol. 7 of the O'Reilly books (the "Xview book!") that programmers are discouraged from using scrollable panels, since they are not openlook compliant. I'd like to be able to display only a part of a large graph and allow the user to scroll about. Now, I get the feeling that the "right" way to do this would be to use a canvas and use Xlib routines to draw the graph (do I catch on fast or what?) But, it seems like it would be SOOO easy to use a scrollable panel instead. So, heedlees of all warnings, I tried to use one. It didn't work. But, I've seen a program that actually uses scrollable panels, and it appeared to work just fine. I'm running olwm on a sun4 using Open Windows 2.0, and the program I saw work was compiled on a sun3 where Openwin does not reside. I suspect that the libraries I'm using and the ones used when compiling/loading this other program are different... Has anyone used scrollable panels in an environment similar to mine? Or should I take Dan Heller's advice and stay away from them? Please respond via e-mail if convenient since I don't get to read news very often... Edwin Elberson ewe@gator.cacs.usl.edu
