[PyQt] Fwd: How can i know that there are no rows in QTreeView??

[Jeba raj]

Hello all.

I'm using QTreeView with QDirModel to list the contents of a directory..
When a user selects an item(or a row) i'm removing it from the tree view
using the below method

setRowHidden (self, int, QModelIndex, bool)

How can i know that the tree view is empty or all rows are hidden?? Rowcount
and Columncount doesn't seem to help.. Expecting your answers.. Thanks
