How to edit QTreeWidget item?

[chaltier]

Hi, i am using QTree Widget to display some number values..

Whenever an object is added to the scene, I wan the child of the Qtree widget to count the total number of object..

So i need the child to be able to update by itself..

How do i access the child and modify its value?

thanks..

Like usually in C++ -- through a pointer to an instance (object).
