zhengtianzuo系列-Qt写入卸载信息

[weixin_38113797]

Qt的QSettings提供了非常方便的注册表读写写入:```//写入注册表void setRegValue(    QString strPath, QString strItemName, QString strItemData){    QSettings reg(strPath, QSettings::NativeFormat);    reg.setValue(strItemName, strItemData);}```读取:```//获取注册表QString getRegValue(    QString &strPath, QString strItemName){    QSettings reg(strPath, QSettings::NativeFormat);    return (reg.value(strItemName).toString());}```删除:```//删除注册表void delRegValue(    QString strPath, QString strItemName){    QSettings reg(strPath, QSettings::NativeFormat);    if (strItemName != nullptr)    {        reg.remove(strItemName);    }    else    {        reg.remove(strPath);    }}```Windows上程序的卸载信息在注册表的这个位置:"HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\我们直接向这个位置写入注册表信息即可需要完整代码请访问 QtReleaseExamples
