Hierarchical Header View

[skebanga]

I need to display hierarchical headers in a table.

I found HierarchicalHeaderView from qt-apps.org, which works, to a degree.

The problem I'm having is that QHeaderView::saveState() and QHeaderView::restoreState(const QByteArray&) don't work, and as such, my users can't save their column widths for subsequent runs of the program.

• Is there a better hierarchical header view / table view available?
• Is there a way to easily implement hierarchical headers in a QTableView such that I can leverage the existing saveState / restoreState?
• How would I go about implementing saveState / restoreState in HierarchicalHeaderView?

For the qt-apps.org version of HierarchicalHeaderView, the source code, updated for Qt 5, can be downloaded from here

Further investigation into the issue has revealed that HiearchicalHeaderView re-implements the header views sections, and there is no relationship between the QHeaderView notion of sections, and the HiearchicalHeaderView notion of sections.

As a result, the following calls are available, but return incorrect data.

QHeaderView::count() returns 0
QHeaderView::sectionSize(int) returns 0
QHeaderView::logicalIndex(int) returns -1
etc...

The upshot of this is that there is a significant amount of work required in HierarchicalHeaderView in order to make in feature complete, and that the way it is currently implemented is not symbiotic with QHeaderView

That essentially leaves 2 questions.

• Does an open source feature-complete hierarchical header view exist?
• Is there a way to easily implement hierarchical headers in a QHeaderView?
