Hey Luca,
you can always access the native DOM element of a qooxdoo widget. Take a look
at the example:
var c = new qx.ui.embed.Canvas();
this.getRoot().add(c);
qx.ui.core.queue.Manager.flush();
var canvasElement = c.getContentElement().getDomElement();
The flush is used to bring render the canvas to the DOM which creates the DOM
element. With the canvas element you should be abel to access all the stuff you
need.
Regards,
Martin

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
