I'm not sure what your 'getIFrame()' method does, but let me elaborate
on what Fabian wrote:
var myIframe = new qx.ui.embed.Iframe; // this is your Iframe object
from within your qooxdoo app
myIframe.setSource("http://qooxdoo.org";); // you need this to have a
ContentWindow!
var theContentWindow = myIframe.getContentWindow(); // I've used this
call before, worked for me
// or:
var theContentWindow = qx.html.Iframe.getWindow(myIframe); // should be
same as above
theContentWindow.scrollBy(...); // use it
A few more notes:
o you need a document 'setSource'd or even loaded in your iframe for
getContentWindow to return something useful
o if your 'getIFrame()' method returns a vanilla Iframe object it's no
surprise getContentWindow() returns null
o so it might be a good idea to wrap the call to getContentWindow() into
an event handler that handles the "load" event of the iframe
o I'm not sure the 'getIframeNode()' method you used returns something
usable for your problem
