Haven't found one either. But checking height while adding elements is
ok - have it almoust working already. Well, almoust - the problem is
that when height or width properties are set once, you can't take it
back. So, while panel shows the desired behaviour while adding
elements, it remains "big" when elements are removed. I've already
tried:
scrollPanel.setWidth("");
scrollPanel.setWidth(null);
but no luck. I've also tried to set the style-attribute directly with
DOM.setStyleAttribute(scrollPanel.getElement(), "width", "");
but no luck either.
Sadly, i haven't found a "removeStyleAttribute"-method.
Any ideas?
Thx
