I've got a couple questions for anyone who knows a bit about Xview: 1. When many Scrolling List calls are made in quick succession, programs tend to dump core or otherwise go wild. Is there any way of avoiding this short of putting delays between calls? 2. The documented Xview bugs (such as inablility to modify the Scrolling List font, etc.) are getting in the way of much work. Are there any patches/new versions of Xview, etc. out there that I can use? 3. Is there any software anyone has to replace/imitate Scrolling Lists that works better than the standard implementation? Help in this area would be greatly appreciated! Thanx! - Tim Bessie

Is there any > way of avoiding this short of putting delays between calls? What do you mean by "Scrolling List calls"? Are you referring to xv_create(owner, PANEL_LIST,...) or xv_set(mylist,...) or xv_get(mylist,...)? And what exactly do you mean by "quick succession"? Many of the apps that I have built use many scrolling lists. While they certainly are far from perfect (the OPENLOOK spec is probably more at fault here than Xview), I haven't experienced this behavior. > > 2.

While its not very intuitive on how to do this, its certainly do-able. Send me some email if you want a little ditty to do this. > 3.

Personally I'd like different colors for each line, editable columns (like a scrolling panel of panel_text items), deleting all entries at a pop, no more annoying flicker, faster scrolling,... Some time ago I managed to get a textsw object to behave like a scrolling list. But that was before XView 1.0 Frank G. Some other info would also be helpful, like what kind of machine, what OS, what version of the OS, what version of XView...etc.
