I am working on an application which will display and allow manipulation of heirarchical graphs. I was reading in O'Reilly vol. 7 (Xview) Xview programmers are discouraged from using scrollable panels; however, they seem to be just what I need (at this point, anyway.) Now, I have seen an application which used a scrollable panel and it worked just fine. This was on a Sun 3 under OLWM. I have not been able to get a scrollable panel to work AT ALL on a sun 4 under OLWM (however, I'm using openwin on the sun 4 but not on the sun 3). So if I can't get it to work anyway, the question is pointless. Why (in more specific terms than in O'Reilly, please!) is using a scrollable panel discouraged? Is it because they may not work at all in the future (or am I experiencing the future now?) Has anyone used a scrollable panel successfully under similar conditions (sun 4, openwin)? Please respond via e-mail if convenient, since I only have time to read news a few times a month...! Also, apologies if this is the wrong newsgroup for this question, but I couldn't find an Xview group... I saw a couple of messages about com3 and com4 problems with windows 3.0. I had these problems myself - it's because the BIOS has the addresses for com1 and com2, but not com3 and com4. Apparently, this doesn't bother Procomm, but it does bother windows. I've seen a lot of articles about setting certain things in the win.ini file to fix this, but I only had to do two things: 1) Make sure the Com4Base (my modem's on com4) in win.ini was set correctly (I hope I'm remembering all this right... if not, it's close!) and it was set correctly. 2) Make sure I put the address of com4 in memory before starting windows. You can use debug for this, but look around ftp sites for programs that do this for you. cica might be a good place to start looking. You've probably gotten replies already since I'm posting this 4 days after you, but I figured, just in case.... If you haven't got it fixed yet, email me and I'll be more specific.
