Hi Werner,
here's a solution I came up with a while ago. Might not be the most
elegant, but it works:
// scroll to to the last entry if a message is added
htmlEmbed.addListener("changeHtml", function(ev) {
var element = this.getContentElement().getDomElement();
// need to use a timeout to make sure the HTML is updated
window.setTimeout(function() {
var lastChildIndex = element.childNodes.length - 1;
if (lastChildIndex > 0) {
var lastChild = element.childNodes[lastChildIndex];
qx.bom.element.Scroll.intoViewY(lastChild);
}
}, 0);
});
As you can see, the trick is to do the scrolling asynchronously so the
browser can update the DOM first.
Regards,
Daniel
