Ah, I finally see what you are doing with that iterator. You are using that to find and remove the item elements from the view.
What you are doing "wrong" is just abusing an existing method. You generally try to not change the contracts of methods by overriding them and assigning them different functionality, as it tends to break existing code, and just be confusing. There are many ways to do this kind of thing. The simplest would probably be to define a new method "getItemElementsIterator" or whatever else you want to call it, and return the flow panels iterator that you want with that new method. -Ben On Mar 30, 10:35 pm, Vhann3000 <[email protected]> wrote: > On Mar 30, 12:26 pm, Vhann3000 <[email protected]> wrote: > > > Second, I may very well be wrong, but the way I understand it, if I > > don't override the ScrollPanel's iterator(), then it will return the > > VerticalPanel (as the VerticalPanel is the sole child widget of the > > ScrollPanel).
