Java Forum / General / November 2006remnants of deleted component still displayed on screen.
I cant for the life of me figure this out. I have a JPanel inside a JScrollbar inside another JPanel inside a JPanel inside another JScrollBar inside an extended JDialogBox. I have code to remove an element from the innermost JPanel. I then called validate(); on the inner most JPanel and JScrollBar. However, the graphic of the component remains. So then I proceded to call validate on all components in the heirarchy, and still the graphic remains. It's probably something absoletly retarded that I'm forgetting to do, but it is irritating the hell out of me. Part of the code is adding and removing componenets. The user selects a componenet that he/she does not want anymore, and it is removed from the list (the list exists inside the innermost JPanel). As long as there is 1 or more instantiated elements, it works fine. I am guessing because it paints itself over the remnants of the deleted element. However, when I delete the last element, I would like just a grey background to show. I did try setting the background to grey after removing all components, but to no avail. > I cant for the life of me figure this out. > [quoted text clipped - 9 lines] > It's probably something absoletly retarded that I'm forgetting to do, > but it is irritating the hell out of me. > Part of the code is adding and removing componenets.

I would attempt to add the innermost JPanel to the innermost JScrollPane again using setViewportView or similar. This has obviously not been tested etc but I seem to recall that it works. All the best, Robert Thank you thank you thank you Did the trick... > > Part of the code is adding and removing componenets.
