David Díaz :
Under Windows probably yes.
You could create same Tree on Shell that is not visible on screen,
make it big enough to fix full tree and use WM_PRINT (see MSDN) to get
image. But this is not portable, so try to find better solution.

I am not sure, but you can try to use Control.computeSize() with
SWT.DEFAULT sizes.
