图片放在QLabel上，注意设置QLable一些属性
QImage img("test.png"); img = img.scaledToWidth(400,Qt::SmoothTransformation); QLabel* label = new QLabel(this, Qt::FramelessWindowHint|Qt::Tool); label->setPixmap(QPixmal::fromImage(img)); label->setGeomtry(0,0,400,300); label->setAttribute(Qt::WA_TranslucentBackground); label->show();
