Best way to have check box click functionality on in checkbox region of QTreeView?

[deepal_de]

Hello,
This disables the complete row.How to disable single item in a row??

i have a QTreeWidgetItem* p, 'p' has about 12 items (12 Columns). i need to disable items in index 5,6 and 8. Other items should not be changed.
Any idea how to do that?

Thanks....
