I assume you are working with a qooxdoo UI button here (qx.ui.form.Button or similar). If that's the case you need to write
--snip-- qx.bom.element.Scroll.intoView(button1.getContentElement().getDomElement()); --snip-- to get it working. "getContentElement()" will return an instance of a "qx.html.Element" which is a high-level abstraction of a DOM element (used for queuing and lots of other stuff). To get the real DOM element you have to call "getDomElement()". And that's what the "Scroll" class is working with as an input parameter. Hope this helps, Alex ------------------------------------------------------------------------------ _______________________________________________ qooxdoo-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/qooxdoo-devel
