QT 中设置按钮图片和文字的两种方法

void setIcon(const QIcon &icon)

void setText(const QString &text)

QLabel* label = new QLabel();
    QLabel* label2 = new QLabel();
    label2->setStyleSheet(QString("border:1px solid red;"));
    label->setStyleSheet(QString("border:1px solid red;"));
    label2->setPixmap(QPixmap("E:/QtCode/QPushbuttonPaintIcon/upgrade.png"));
    label->setText("升级工具");
    label->setFixedWidth(80);
    QHBoxLayout* myLayout = new QHBoxLayout();
    myLayout->addSpacing(10);
    myLayout->addWidget(label2);
    myLayout->addSpacing(30);
    myLayout->addWidget(label);
    myLayout->addStretch();
    ui->pushButton->setLayout(myLayout);
