Custom QHeaderView in Qt 4.1.1

[Tair]

Hi guys!

I'm using Qt 4.1.1 and have come across an unsolvable (at least to me) problem:
Normally text in sections of horizontal header view are drawn horizontally.
The question is - how to make that text drawn vertically, i.e. rotated by 90 degree? (see the attachment picture)
I've tried this:

class MyCustomDelegate : public QAbstractItemDelegate
{
     ....
public:
     void paint(...){
         doMyCustomPaint();
     }
};
...
// usage
tableView->setModel(myModel);
myCustomDelegate = new MyCustomDelegate(this);
tableView->getHorizontalHeader()->setItemDelegate(myCustomDelegate);

class MyCustomDelegate : public QAbstractItemDelegate
{
     ....
public:
     void paint(...){
         doMyCustomPaint();
     }
};
...
// usage
tableView->setModel(myModel);
myCustomDelegate = new MyCustomDelegate(this);
tableView->getHorizontalHeader()->setItemDelegate(myCustomDelegate);

To copy to clipboard, switch view to plain text mode 

But code above does not help. Have any idea?
