QIcon icon = QIcon("/home/work/QVFiles/style/localavatar.png");
QPixmap pixmap = icon.pixmap(60, QIcon::Disabled);
QLabel *label = new QLabel(this);
label->setGeometry(35,5, 60, 60);
label->setPixmap(pixmap);
label->setScaledContents(true);
这个显示出来的是黑白的图片；
QIcon icon = QIcon("/home/work/QVFiles/style/localavatar.png");
QPixmap pixmap = icon.pixmap(60, QIcon::Disabled);
QRect avatar = QRect(35,5,60,60);
p.drawPixmap(avatar, pixmap);
