Thanks for aamer4yu's reply!!! He suggested me to subclass QHeaderView and implement my own checkbox. but I want to know whether there is an easyier way to reach this.

Could you give me some helps?Thans a lot!!

QTreeWidgetItem::setCheckState

EDIT: Sorry,, didnt realise fast that it was header .
For that I guess you will need to subclass QHeaderView and implement your own checkbox.
