Styling the tear-off handle of a QMenu?

[dictoon]

Is it actually possible to customize the look of the "tear-off" handle of a QMenu with stylesheets? The documentation (http://doc.qt.nokia.com/4.6/stylesheet-reference.html) seems to indicate it's possible: "The tear-off is styled using the ::tear-off" (on styling QMenu).

Here's what I've tried:

QMenu::tear-off
{
    background-color: green;
    color: red;
    border: 10px solid yellow;
}

QMenu::tear-off
{
    background-color: green;
    color: red;
    border: 10px solid yellow;
}

To copy to clipboard, switch view to plain text mode 

However this has no effect whatsoever, neither on Windows (Vista) nor on Mac OS X (10.4). I also tried "QMenu::tear-off::item".

I'm using Qt 4.6.2, latest stable.

Cheers,
