disable clicked() signal

Hello,
I have a QTreeWidget with some QTreeWidgetItem in and i'd like to know if there is a way to disable the "clicked()" signal for a specified item.

item1
item2
item3
|___subItem3 --> i want to disable(just for subItem3) the clicked() signal emitted when the item is clicked

thx

Why do you want to do that?

You could try making it non-selectable.
