Hi! I need to be able to detect (and display a popup for example) when a certain element in a document (let's say a "<warning>" element) becomes visible. That includes scrolling the view, resizing, etc. Whenever this particular element is visible, i need to know. :-) An observer seems like the best solution, but I haven't found one that could observe only a single element (nsViewObserver is bound to the view manager), and that can handle a paint event. Any help will be very much appreciated. Thanks, Catalin.
