今天在重写QListView的 paintEvent方法时
运行时遇到了如下问题（并且文字并没有显示）：
QWidget::paintEngine: Should no longer be called
QPainter::begin: Paint device returned engine == 0, type: 1
其解决思路是：
将QPainter painter(this);这一句改成QPainter painter(this->viewport());
我的问题就解决了
QPainterpainter(this);
painter.drawText(rect(),Qt::AlignCenter,tr("Draganddropfile(s)here"));运行时遇到了如下问题（并且文字并没有显示）：
QWidget::paintEngine: Should no longer be called
QPainter::begin: Paint device returned engine == 0, type: 1
其解决思路是：
将QPainter painter(this);这一句改成QPainter painter(this->viewport());
我的问题就解决了
