Hi

I would like to know if for u the sort of rows works in a VIRTUAL
table, in an application of your own or in the demo application.

Thanks,
Val

with VIRTUAL, you have to reorder your data source (i.e SQL) and redisplay
the data.
When using static loading of data, use comperators as shown in the Demo.

Hi

Thanks for the answer, I have reordered my data from sql.
However, after sorting I refresh the data with tableViewer.refresh();
but still the table contains stale data and only when selecting a row
from the table the new data is show on all visual rows of the table.
Then when scrolling down the same thing old data is shown and only
when selecting some row it is refreshed.
I keep my data in a cache in pages of 40 elements but I clear the
cache when doing the sort and I can see that the update method of the
ILazyContentProvider fills up with new data which however is not show
until selecting some row.

Thanks
Val

Hi,

sorry for the late reply. I just added sorting for the VIRTUAL
TableViewer in the ControlsDemo (tab TableViewer) the way I think it
should be done - and it works. There are no stale rows or similar.
You could check out the code from CVS HEAD and have a look what's
different from your implementation. The actual sorting is done in
CTableViewer#sort, line ~382.
If you still think there is a bug feel free to file a BugZilla entry.

Cheers,
Rüdiger

Hi

using RAP 1.0.1 sort on virtual table viewer works better :)
However there is still a problem when the amount of data showed in the
table can not be displayed at once (is more thant the visible part of
the table)
for this I have created bug no. 211790 it contains the steps and patch
to reproduce on demo application

Cheers,
Val
