[platform-swt-dev] XP Scrollbars becomes temporaly visible...

[Arnaud De Muyser <ademuyser@xxxxxxxxxx>]

Hi,
I'm experiencing this funny, strange,
but buggy situation:

I use a Canvas widget with H_SCROLL
and V_SCROLL styles, and hidde both scroll bars using getVerticalBar().setVisible(false)
(this is done to support mouse wheel,
and scrollbar user viewing and gesturing are other widgets ).
Sometimes in my code I call getVerticalBar().setSelection(
value ), otherwise mouse wheel scroll from bad value

On win32 if I set my desktop style to
"Windows classic Style", I never see the hidden scroll bar as
I expect (good!),
but if I set my desktop style to "Windows
XP style", each time getVerticalBar().setSelection() is called the
hidden scroll bar s
are drawn, and "removed" by
next Canvas's paint event.

Does any body have already seen this
behavior ?
Is it a SWT problem or XP one, how I
can correct this  ?

Thanks for your help.

Arnaud.
