Grid row headers [message #46954] |

I called setRowHeaderVisible(true) and I get a row header. Now how can I
specify what the values for the row headers are? I don't want numbers, I
want text labels that I can specify.
Thanks,
- Jason

Just tried it and for me it works but I think the naming is not 100%
correct and we should rename it to RowLabelProvider?
I've attached my test-snippet.

Ah...I think I found it. I extended GridColumnLabelProvider and used
GridViewerColumns to add the label provider to each column. Not very
intuitive this way since the row header isn't really a column, but it
seems to work.
Should GridViewer.setRowHeaderLabelProvider() do this as well? I tried
that but it didn't seem to work for me. Might have been something I did
wrong though - I've only been using the Grid API for 30 minutes or so... :)

Hi Jason,
setRowHeaderLabelProvider should work. Alternately you can do as you
did (although you should only need to actually implement
getRowHeaderText on one provider).
Tom - do you know why this might not be working?
regards,
-Chris
