Hi , I am fairly new to GWT and my requirement needs a glasspanel to be used. But due to the heavy size of incubator.jar file i would like to just copy the GlassPanel class and GlassPanelImpl into my own workspace and create a custom glasspanel . This would remove the dependency on incubator.jar file. All is well at compile time. But when i compile it , it throws an error saying "GlassPanelImpl cannot be abstract" Please suggest if i am missing anything. Any help would be greatly appreciated.
Thanks and Regards, Surya.
