Hi All,

I want's to use RowHideShowLayer given in the org.eclipse.nebula.widgets.nattable.core , so i have created the instance of RowHideShowLayer and then created an object of SelectionLayer and passed the RowHideShowLayer object into it's constructor then used some of the functions of row hiding, it worked but there were two problems.

1. Rows were hided but index and positions were not updated.
2. ColumnHideShowLayer stopped working because it works when it becomes the underlying layer of SelectionLayer but as described above i also wants to use RowHideShowLayer.

So now how i can use both the layers that is ColumnHideShowLayer and RowHideShowLayer at the same time? as both wants to become the underlying layer of SelectionLayer to work properly.

Why the indexes and row positions are not updating when using row hiding functions, in my opinion most probably event list is not updated and may be RowReorderLayer is not working properly also, how to get it work ?

Any help will be appreciated,

Thanks,
Safdar Khan

If you use GlazedLists you should consider using GlazedListsRowHideShowLayer because of issues regarding GlazedLists handling in combination with hiding rows

There is no such constraint that the hide show layers need to be directly the underlying layer of SelectionLayer. The SelectionLayer needs to be on top of both for the index transformation of the selection, that's all. And the transformation is done on handling the corresponding events.

I don't understand why you are thinking there is such a constraint.
