[提问]“intersect”: 不是“QRegion”的成员 [复制链接]

QT5.1中QRegion没有了 intersect。请问下面的代码如何调试：


    for (int i = 0; i < image.width(); ++i) {
        for (int j = 0; j < image.height(); ++j) {
            QRect rect = pixelRect(i, j);
           if (!event->region().intersect(rect).isEmpty()) {
                QColor color = QColor::fromRgba(image.pixel(i, j));
                if (color.alpha() < 255)
                    painter.fillRect(rect, Qt::white);
                painter.fillRect(rect, color);
            }
        }
    }

有空没空，多看看帮助文档。首先，它他告诉你Qt5有这个东西，其次告诉你用什么可以替代它。

The following members of class QRegion are part of the Qt compatibility layer. We advise against using them in new code.

QRegion QRegion::intersect(const QRect & rect) const
Use intersected(rect) instead.
