Hello everybody,
I have a SashForm with a TreeViewer on one side of the Sash. The
TreeViewer has SWT.BORDER set (see end of the post for a code snippet).

It seems that RAP renders the TreeViewer a little bit wider than it is
intendet, and therefore the TreeViewer's scroollbars are partly overlaid
by the Sash in both directions (vertically and horizontally).

The screenshot tv_on_sash.png shows how it should be rendered (and is
rendered with SWT), tv_on_sash_rap.png shows the (slightly wrong)
rendering by RWT.

This is not a critical problem since it can be solved by turning off
SWT.BORDER on the TreeViewer, but it is at least distracting for
single-sourcers. Also I could not reproduce this with an different
control than a TreeViewer (e.g. the text widget on the left side is
shown correctly, I also tried a TableViewer which does not show this
behaviour). My Target is 1.2 M5.

Regards,
Bj

Hi Björn,

your snippet renders fine here. Which version do you use? Any custom themes?

Hi Ralf,

I am using RAP Version 1.2.0-M5-20090210-1243. No custom Themes. What
else could I check?

Greetings,
Björn

Could you check with latest CVS? As we cannot reproduce the problem here
chances are that this has been fixed by a change in the SashFolder past M5.

Hi Ralf,
I checked against current CVS version and this issue seems to be fixed.

Thanks for your advice!

Björn
