Re: how to control the pixel sizes of a Grid?

I gave it a last try: I bundled the code that creates the panels into
a single method, so that I can easily switch between the panel and no-
panel version. This should make sure that there are no other things in
the code that may cause the verttical space.

In the no-panel version I explicitly set the pixel size of the image.
But there is still the verrtical space. So by just switching 2 lines
of code you can verify that the Panel version works, but the non-panel-
version does not. There must be something wrong with the Image itself.
However, I verified (window.alert) that the image.getHeight returns
20.

I can live with the panel version, but I cannot live with not knowing
what's wrong with the non-panel version. :-) I currently wonder if
there are some styles associated with the Image class. (How can one
retrieve the assoicated styles?) However, the Image style in gwt/
standard/standard.css is empty...

Below is my code. Maybe someone is also interested in finding out
what's going on there.

Thanks
Magnus
