special visual

[yves COPPE]

Hello

1) In the application overview window, when you clic the "groups" and 
look at the right side of the window, you see a "widget" button at 
the bottom. When you clic it and change the view, you see a visual 
effect on a part of the window with the changing of the flds
How can I write the same thing in a script ?

2) How can I make modern columns as they appear just above this button ?

Thanks.
