I was curious about that too, Benoît. And, it was the first thing I tested after getting 3.6 installed. I didn't report my findings, because I had no idea that you would have remembered. But you did! :-) Did 3.6 fix the problem? Partially. DrawingArea.Clear now works with both QT4 and GTK(2). But I still need to call DrawingArea.Show to get the drawing to display properly after any modification of a TextBox or ValueBox control's Value property. (Note: DrawingArea.Cache = True) Just FYI: If I wrap each line draw in a Paint.Begin/End structure, the first line will be displayed until the second line's Paint.End is called. As so in pseudo-code: Paint.Begin Draw red line Paint.End Modify ValueBox.Value Paint.Begin Draw blue line Paint.End 'The red line disappears here and blue line is not displayed If I do not wrap each line in its own block as in: Paint.Begin Draw red line Modify ValueBox.Value Draw blue line Paint.End then nothing is displayed unless I call DrawingArea.Show after Painting. I can provide a project if you wish, but I think calling DrawingArea.Show is a very workable solution. And, thank you for remembering. -- Lee __________ "Artificial Intelligence is no match for natural stupidity." ------------------------------------------------------------------------------ Comprehensive Server Monitoring with Site24x7.
