Qt-QProcess:啟動外部程序失敗

使用QProcess啟動外部exe文件：

​QString exepath = QApplication::applicationDirPath() + "/Series/loads.exe";            
if (QFileInfo(exepath).exists())
{
    if (m_acouProcess == nullptr)
    {
        m_process = new QProcess(this);
    }
    m_process->start(exepath);
}

軟件總是起不來，查資料發現是沒有設置工作目錄，加上下面兩句就可以了：

​QString workpath = QApplication::applicationDirPath() + "/Series";                
m_process->setWorkingDirectory(workpath);
