Is adding this support somewhere in the pipeline?

Hi,

looking at the current architecture of the NatTable, this doesn't make sense. JFace ColumnLabelProvider is working with ViewerCell objects, which aren't used by the NatTable as it has its own ILayerCells. The JFace IContentProvider is used with JFace Viewer objects. And the NatTable is not a JFace viewer.

So, no it is not in the pipeline and IMHO it doesn't make sense to do this. I'm not quite sure if it is possible.

But it wasn't discussed with the project team already. Maybe I'm seeing things wrong and it will be added in the future.

Greez,
Dirk

I'm sure an adapter layer could be created to make this work, but Dirk is right in that the concepts are a bit different so a decent amount of translation would be required. Personally I'd need to become more familiar with the JFace api to do this properly. If this is important to you and/or if you have JFace development expertise you can bring to bear on this please let us know.

Thanks,
Edwin

I think it wouldn't be too much of a problem to write a viewer that can use an IStructuredContentProvider to populate the rows of a NatTable. The big difference with the regular JFace table-like viewers is that they are row/column based, whereas NatTable is a grid. So one would have to introduce some kind of column model which which works with the content provider to populate the cells and provides configuration. Also, selections, actions (see, for example StructuredViewer.addDoubleClickListener()), etc. should be translated into a row/column based vocabulary. It's certainly a couple of weeks work, though.
