QTreeWidget::itemAt() returns a pointer to an item in a specific point relative to the widget's top-left corner. Remember the widget is probably the view's viewport and not the view itself.

I don't understand. If you click outside any item then the returned pointer will be null.

found i think the answer
QModelIndex index = this->indexAt(pos);
then in the code..
if(index.isValid()) .....

You're using item based approach, so:
QTreeWidgetItem *item = indexAt(pos);
if(item) {
// item is valid
}
