Version: CVS (using KDE KDE 3.1) Installed from: RedHat RPMs Open a file. Make a change. Tab gets the modified icon. Now undo the change. Modified icon does not disappear from tab.
I can confirm this in KATE also. I think it was teatime that fixed it when we still had the asterix, but whoever changed it to the little icon, broke it.
Yeah, this broke a few weeks ago. I think it was along with the addition of the "file has been externally modified" notification. I've had a short look at it, but I keep thinking that if we're really porting the whole GUI to KMDI in a few days/weeks/months (I have no idea if/when, really) won't this be among the things we will have to redo anyway? Note that the problem with Kate is different from the problem with QEditor. With Kate it's just our tracking that is the problem, with QEditor you most of the time _cannot_ undo all changes anyway. (This is due to the indentation and the private nature of the underlying Qt editor widget features.)
QEditor has been removed for KDevelop 4 and none of these bugs will be fixed between now and then.
