Question

怎样在QGraphicsView控件上动态的绘制图形QGraphicsItem的用法

Answer 1

大概是这样子的

其实就是直接调用addPixmap

QGraphicsScene *scene;
QGraphicsView *view = new QGraphicsView( scene,this );
QPixmap *pixmap = new QPixmap("xxx.png");
scene->addPixmap(pixmap );
view->show();

==================================

试下这样

scene->addPixmap( QPixmap("xxx.png") );
