Hierarchical TreeView

[cia.michele]

GoodMorning to all,
thanks to the suggest by this forum, I built a component to show data in two-level table, created by two QTreeView.

It's work fine but it is not so pretty on the code style; more than this, it causes some SEGMENTATION FAULT to application, especially when I request the contextMenu.

This component is made by an outher QTreeView, and an inner QTreeView. It's work fine when I use the outher one, but when I request the contextMenu of the inner one, it create problem and show a message like

ASSERT failure in QMutexLocker: "QMutex pointer is misaligned", ...

ASSERT failure in QMutexLocker: "QMutex pointer is misaligned", ...

To copy to clipboard, switch view to plain text mode 

It make my application not so stable. How can I fix this problem?

I attach the files about this my component.

Thanks for your time.
