TextViewer and revealRange [message #24028]

Hello.

I want to make a selection in a text viewer visible. The selection itself works fine, but the reveal
not.

I set up my text viewer with textViewer = new TextViewer(form.getBody(), SWT.WRAP | SWT.V_SCROLL);
and then just call textViewer().revealRange(600, 5); (the text has more than 3000 chars), but
nothing happen. I want that the viewer automatically scrolls to that 600 offset.
Do I need to do something further to accomplish that?

Regards,
Kai

My text consists of two lines (one line break), but is quite long and is wrapped multiple times by
the text widget. If I try to reveal a range in the first line everything works fine. If I try to
reveal a range in the second it fails. Maybe because the revealRange of the TextViewer doesn't pay
attention to wrapped only lines?
