Grid row headers [message #46954] Thu, 17 January 2008 20:09 Go to next message

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

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

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.
