Change disabled QCalendarWidget weekends color

Question

I want to customize QCalendarWidget and I can't change the weekends colors for the disabled state. This is how it looks right now:

I would like to gray out the red. I know that you can set the weekends colors with:

QTextCharFormat weekendFormat;
weekendFormat.setForeground(QBrush(Qt::green, Qt::SolidPattern));
m_ui->calendarWidget->setWeekdayTextFormat(Qt::Saturday, weekendFormat);
m_ui->calendarWidget->setWeekdayTextFormat(Qt::Sunday, weekendFormat);

but this doesn't affect the disabled state. How can I affect the disabled state and set different disabled colors for the weekend?

Thanks!

If you want to get different colors for enabled and disabled states, you can subclass and reimplement the change event handler:

void MyCalendar::changeEvent(QEvent *event)
{
    QCalendarWidget::changeEvent(event);
    if (event->type() == QEvent::EnabledChange)
    {
        QColor color;

        if (isEnabled())
        {
            color = Qt::blue;
        }
        else
        {
            color = Qt::yellow;
        }

        QTextCharFormat weekendFormat;
        weekendFormat.setForeground(QBrush(color, Qt::SolidPattern));
        setWeekdayTextFormat(Qt::Saturday, weekendFormat);
        setWeekdayTextFormat(Qt::Sunday, weekendFormat);
    }
}
