Tooltips & CTreeCtrl
Roger M. -- RUNDEWOOD@cerner.com Thursday, September 19, 1996 Environment: VC++ 4.0, Win 95 I'm developing an app under VC++ 4.0 with a CTreeCtrl on the main window. I've just recently noticed that when I add items to it that cause a horizontal scrollbar to appear and I rest my cursor over the long item, a tooltip appears. I've never seen this functionality before. Does anyone know how to turn it on/off (there is no tree style bit for tooltips). I just recently installed IE 3.0. Was a new Comctl32.dll installed with this new functionality? If so, does this mean that I won't be able to turn the tooltips on/off until I upgrade VC? I like the tooltips, but the problem is that they don't always appear. They only seem to appear after clicking on a tree item, then moving focus to another control, then resting my cursor over the long item.

I don't believe you can turn it off. However, it should work fine and I don't believe you should worry about it as *all* applications that use a tree view (eg Windows Explorer) get this as well, so it's presense will be consistent accross applications. If you turn it off, your users may wonder why and complain that they cannot see long items like they can in every other Windows 95 application. >I like the tooltips, but the problem is that they don't always appear. >They only seem to appear after clicking on a tree item, then moving >focus to another control, then resting my cursor over the long item. Strange, they seem to work OK for me. And they work OK in Explorer Perhaps it is something to do with your active windows or focus. I think it is a symptom of some other problem rather than a problem with the tooltips themselves. Roger.
kellyw@mailgate.seer.com Monday, September 23, 1996 I've had problems with non-MFC, Win32 tooltips only appearing when you actually clicked on the control. The problem was attributed to incremental linking. After a full relink, the problem disappeared. Maybe this is the same problem? ______________________________ Reply Separator _________________________________ Subject: Re: Tooltips & CTreeCtrl Author: mfc-l@netcom.com at mailgate Date: 9/23/96 6:07 PM >I'm developing an app under VC++ 4.0 with a CTreeCtrl on the main >window.
