Exemple #1

void QMultiScreen::setDirty(const QRect &rect)
{
    const int n = d_ptr->screens.size();
    for (int i = 0; i < n; ++i) {
        QScreen *screen = d_ptr->screens.at(i);
        const QRegion r = screen->region() & rect;
        if (r.isEmpty())
            continue;
        screen->setDirty(r.boundingRect());
    }
