QToolButton prevent from moving

Is there a way to prevent QToolButton from being "pressed in" when clicked? I read somewhere that setting

button->setCheckable(false);

should do the trick, but it doesn't.

There is a way to do it via a QProxyStyle:

class ButtonProxyStyle : public QProxyStyle
{
public:
    const int pixelMetric(PixelMetric metric, const QStyleOption *option = 0, const QWidget *widget = 0) 
    {
        int ret = 0;
        switch (metric) 
        {
        case QStyle::PM_ButtonShiftHorizontal:
        case QStyle::PM_ButtonShiftVertical:
            ret = 0;
            break;
        default:
            ret = QProxyStyle::pixelMetric(metric, option, widget);
            break;
        }
        return ret;
    }
};

And then, with your button:

myToolButton->setStyle(new ButtonProxyStyle);
