[QT学习]拷贝文件

sourceDir源绝对路径，toDir目标绝对路径

//拷贝文件：
bool FileOperation::copyFileToPath(QString sourceDir ,QString toDir, bool coverFileIfExist)
{
    toDir.replace("\","/");
    if (sourceDir == toDir){
        return true;
    }
    if (!QFile::exists(sourceDir)){
        return false;
    }
    QFileInfo fi(toDir);
    QString dirPath=fi.absolutePath();//取路径
    QDir *createfile = new QDir;
    bool exist=createfile->exists(dirPath);
    if(!exist)
    {
        createfile->mkdir(dirPath);
    }
    exist = createfile->exists(toDir);
    if (exist){
        if(coverFileIfExist){
            createfile->remove(toDir);
        }
    }//end if

    if(!QFile::copy(sourceDir, toDir))
    {
        return false;
    }
    return true;
}
