1、测试代码
void MyDrawWindow::paintEvent(QPaintEvent *event) {
int width = this->width();
int height = this->height();
QPainter painter(this);
QColor color(0, 0, 265);
QPen pen(color);
QBrush brush(QColor(255, 0, 0));
painter.setPen(pen);
painter.setBrush(brush);
painter.drawRect(20, 20, 50, 90);
painter.drawEllipse(QPoint(width/2,height/2),20,20);
painter.drawLine(QPoint(80,80),QPoint(100,100));
}
效果图
