in my application, i want to use a Background Image.
I see the example and it work perfect.
Now my problem: in my Screen object i have a form with a large field in the first line, many field in the second and in the third and so on.
I create a GridManager for the second and third line that simulate a table.
So in the first line i use an VerticalFieldManager, then a GridManager and so on.
I think will be simple if i draw the background image in the paint() method of screen and try that the backgrounds of managers would be transparent but i can't find how.
I think that when the managers paint themself, they invalidate the entire region of the screen... how can i override this?
sorry for english
