Surya, In general you should be able to follow along http://code.google.com/p/google-web-toolkit-incubator/wiki/GlassPanel and just include the GlassPanel code in your project as you suggested.
Any chance you are using GWT trunk rather than 1.6.4? If so, check to see you have the latest source code which includes the ie8 rule as seen in http://code.google.com/p/google-web-toolkit-incubator/source/browse/trunk/src/com/google/gwt/widgetideas/GlassPanel.gwt.xml Fred On Wed, Jun 24, 2009 at 4:34 AM, Surya <master...@gmail.com> wrote: > > Hi , > > I am fairly new to GWT and my requirement needs a glasspanel to be > used.
