Get rid of the stupid frustrating focus rectangle in QTreeWidget

[Carlsberg]

Now what beautiful the life would have been if every widget had a function like this

void setFocusRectangleVisible(bool status)

But no, there is none. So after looking over the entire google, I found this example:

http://qt.nokia.com/developer/faqs/736

which works fine. I took that example and replaced some things in there to use it on my QTreeWidget.

Now I have this

void Style::drawControl(ControlElement element, const QStyleOption * option, QPainter * painter, const QWidget * widget ) const
{
	if(element == CE_ItemViewItem)
	{
		const QStyleOptionViewItem *b = qstyleoption_cast<const QStyleOptionViewItem *>(option);
		QStyleOptionViewItem *btn = (QStyleOptionViewItem *)b;
 
		if (btn)
		{
			if (btn->state & State_HasFocus)
			{
				btn->state = btn->state ^ State_HasFocus;
			}
		}
 
		QWindowsStyle::drawControl(element, btn, painter, widget);
 
	}
	else
	{
		QWindowsStyle::drawControl(element, option, painter, widget);
	}
}

void Style::drawControl(ControlElement element, const QStyleOption * option, QPainter * painter, const QWidget * widget ) const
{
	if(element == CE_ItemViewItem)
	{
		const QStyleOptionViewItem *b = qstyleoption_cast<const QStyleOptionViewItem *>(option);
		QStyleOptionViewItem *btn = (QStyleOptionViewItem *)b;

		if (btn)
		{
			if (btn->state & State_HasFocus)
			{
				btn->state = btn->state ^ State_HasFocus;
			}
		}

		QWindowsStyle::drawControl(element, btn, painter, widget);

	}
	else
	{
		QWindowsStyle::drawControl(element, option, painter, widget);
	}
}

To copy to clipboard, switch view to plain text mode 

This is not working as expected because this test is NEVER true

if (btn->state & State_HasFocus)

if (btn->state & State_HasFocus)

To copy to clipboard, switch view to plain text mode 

Can someone please help me? What am I missing? Is the problem the fact that the focus is not on the item itself, but on the tree widget?

I'm using Qt 4.5
