I haven't used the Mdi window classes, but I did just spend awhile trying to get widgets to go away that turned out to still have references coming in. I believe that DeleteOnClose won't do the expected things to a widget that still has direct references pointing to it; that was my experience with that flag, anyway.
This doesn't directly address the mdi/subwindow object question, but if you're using Eclipse, I can recommend using the Memory Analyzer Tool (http://www.eclipse.org/mat/) to see if those widgets are truly still in existence, and if so which other objects have references to them which keep them alive. You just use jmap to create a heap dump, open that binary dump file in Eclipse, and then quick clicks into the Dominator Tree and Show as Histogram (and then filtering for the class in question) will tell you what's actually lurking inside your JVM. This tool recently saved my sanity on an analogous issue... Hope that helps a little! -phil _______________________________________________ Qt-jambi-interest mailing list [email protected] http://lists.trolltech.com/mailman/listinfo/qt-jambi-interest
