Yes, Thomas is right, don't forget to add object to refer as this in a
function. I just demonstrated a workaround for your issue.
It makes sense to add changeFocusedCell event to Table. What does qx
team think about it?
If we speak about passing this, qx.lang.Function.bind(func, self)
architecturally speaks better to me. It's cleaner and easier to read a
code.
obj.addListener("someevent", qx.lang.Func.bind(func, self));
instead of
obj.addListener("someevent", func, self);
There was a discussion not so long ago about it. My 2 cents go for
deprecating existing way of passing self obj to function.
