Unfortunataly I can't think of any way that qooxdoo can provide a way to automatically 'test' whether your application destroyed all widgets that should have been destroyed. This is just because noone but yourself/your app knows which widgets should have been destroyed and which not. As widgets can be reused (search for 'widget pooling') it might be even wanted that widgets are not destroyed after beeing made invisible. Maybe the qooxdoo-developers include a 'getObjectCount' method in their 'qx.core.ObjectRegistry'-class. Then one would be able to create invariants like: 'if I open a custom dialog than after closing it all used widgets must be destroyed' With such a method you could just compare the object-count before and after opening/closing the dialog. Even with widget-pooling this would make sense, because after opening the dialog a first time the global object count shouldn't change on subsequent openings/closings of the dialog. (as a sidenote: destroyed widgets are disposed lazily as documented in the method-signature, but there are ways to force the dispose eagerly for such testing purposes and to get a correct object-count) Alas - this method 'getObjectCount' doesn't exist yet from what I know, but I heard it's still 18 hours to go, before the final 0.8-freeze :D ... PS: if you have an application which changes the page more frequently, then qooxdoo will dispose all of your objects on each page-change from what I know. So you wouldn't have to care for that. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ qooxdoo-devel mailing list qooxdoo-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/qooxdoo-devel
