Adding a button in the header of a QTreeWidget

How is it possible to add a button in the header of a QTreeWidget?

A minimal example is more than welcome... :)

Did you try something like:

Code:

---

QHeaderView *header = myTreeWidget->header();
QPushButton *button = new QPushButton("PushMe", header);
QHBoxLayout *layout = new QHBoxLayout(header);
layout->addStretch();
layout->addWidget(button);

---

I don't know if this works, I'm just spitballing here :)
