[platform-swt-dev] Problem with getting scrollbars to showup on a Table.

Title: Problem with getting scrollbars to showup on a Table.

Hi,

I am developing a new ViewPart which will needs to have three Group widgets. The first group widget will have a table. The second group will have a few buttons, the third group will have a List widget. I can get each of the groups to be displayed but I can't get the table or the list to show scroll bars. My table ends up being longer than the view window, so I need it to scroll.  I would like the table and list to scroll separately.

The source code is below for my ViewPart. Can anyone tell me what I need to do to get the scroll bars??

Thanks
Bob
