QCheckBox通过qss实现状态切换显示不同图标

QString qss = "QCheckBox::indicator:unchecked{ \
        image:url(:/resources/status_close.png); \
        } \
        QCheckBox::indicator:checked { \
        image: url(:/resources/status_open.png); \
        }";

    ui->checkBox->setStyleSheet(qss);
    ui->checkBox->setChecked(true);
