图片按钮 [复制链接]

图片按钮咋么实现啊？？
大侠再赐教下

搜索一下，很多这方面的帖子

    搜所的加了这个
  QIcon icon;
    icon.addPixmap(QPixmap(QString::fromUtf8(":/car_ctrl.png")), QIcon::Normal, QIcon::Off);
    alarm_light_b->setIcon(icon);
    make时

QIcon: No such file or directory
no matching function for call to `QPushButton::setIcon(<unknown
   type>)'
   不知道哪里错了。。。

1楼的大哥，赐教下吧啊

    QPushButton *pushButton;
    //QIcon icon;
    //icon.addPixmap( QPixmap("/home/tsuibin/qtapps/emenu/images/dish_food/2.jpg"), QIcon::Normal, QIcon::Off);
    pushButton = new QPushButton();
    pushButton->setIcon(QIcon("/home/tsuibin/qtapps/emenu/images/dish_food/2.jpg"));
    pushButton->setIconSize(QSize(480,360));
    pushButton->setObjectName(QString::fromUtf8("pushButton"));
    pushButton->setGeometry(QRect(20, 20, 480, 360));
    pushButton->show();
