Unable to find SWT forum, so posting here

Question

Hi,
Has anyone worked on SWT? I am new to it.. and facing this problem.
In my app, I have a login Page and after giving the credentials the next page is displayed. Implementing this in swing is very easy but I have no idea how to implemt in SWT can anyone give me the sample code for the same.
Sorry for posting here.

I am posting a sample code in which from LoginPage i have to go to a TestPage . I guess if i will achieve this, i can achieve the table. Right now, I am getting SWTException : Subclassing not allowed when i press enter key in the password field. Ideally , it should display a TestPage when i press "ENTER" hey in PASSWORD field. here are the files:
