rowCount() is calling for all the top level items

[prasad_N]

I report a bug in Qt bug tracker for this.

You can hide the original header and replace it with your own instance of QHeaderView that is not tied to the model as I understand you want your header to reflect the current view state rather than the model's data.

I want my header to be changed depends on the row I clicked (for ex: if I click on a even row (index.row()%2 == 0 ) I put one header set & for odd row I put another header set).
in this case how a customized header can help me ?
And I could not see any function for setting data (if I customize QHeaderView) rather than QHeaderView::setRootIndex(QModelIndex);

Thanks.
