Even though I've specified that the tree's scroll bars should be turned off,
they appear anyhow. I'm using the last stable build swt-3.1M5a-win32.zip
with files dated 2-19-2005. I create the new tree with these feature flags
and the scroll bars are turned off:
> new Tree(parent, (SWT.FULL_SELECTION | SWT.MULTI | (SWT.H_SCROLL &
SWT.V_SCROLL)))
10000000000000010
Nevertheless, my tree draws with scroll bars and getStyle says scroll bars
are turned on.
> tree.getStyle ()
10000000010000001100000010
============================
Flags:
SWT.FULL_SELECTION
10000000000000000
SWT.MULTI
10
SWT.H_SCROLL
100000000
SWT.V_SCROLL
1000000000

I saw the comment and felt that if I unset both the SWT.H_SCROLL and
SWT.V_SCROLL, the Windows TVS_NOSCROLL should enable and the scroll bars
vanish.
