Hi,
Thanks for the answer. However I did not succeed to make this working by
managing with the layout. I don't know what I am doing wrong. Could any one of
you have a quick look on my attached file( .java. For your help, css is not
having any entry related to this ) and help me out to get rid of this issue.
I know everybody time is precious but I am doing this as of now I have no
option. My code is simple , don't know why this is not giving the required
behaviour.
Every single idea is precious for me at this time.
Regards,
Manish

Subject: Re: working with % for gwt/gwtext widget(Panel) height
I had to think twice to understand you want to set height in percentage.
The size of any widget is affected by the layout is contained in. You can do
setHeight("50%"), add to the parent container setLayout(new FitLayout()), or
just use any of the many layouts available and use panel.add(widget,
layoutdata). ej: rowlayout / rowdata
Have you tried setStyle, or a custom css?
