Jörg,

I've not used it yet, but I think org.eclipse.swt.custom.TableCursor
would be used for that purpose.

There are multiple possibilities since 3.3. SWT-Tables and Trees don't
have the idea of a Cell. That's why JFace holds a bunch of code to make
such a feature available to you (although we don't support SWT.MULTI).

Take a look at the various snippets:

Thanks for your help. Both method does what i want. I have it now done
with the focusCellManager. But a little problem exist here, I got the
columnindex with this focusCellManager.getFocusCell().getColumnIndex(),
but how can i get the index of the row?

This is not possible. SWT doesn't has direct API to fetch the row-index
and for viewers it is most of the time not important because the
Model-Object should hold all the data but you could easily calculate it
from the Cell-Bounds or even better if you are in-single-select-mode
(which you must :-) query to the table for the current-selection-index.
