QT compressed folder

Adopted QZipWriter Of addFile To achieve .
First step ：pro Add... To the file QT += gui-private
The second step ： Add... To the header file ：

#include <QtGui/private/qzipreader_p.h>
#include <QtGui/private/qzipwriter_p.h>

The third step ：cpp Implementation in file ：

bool zipDir(const QString& dirPath,QString SavePath)
{
    
    bool  ret;
    QZipWriter *writer = new QZipWriter(SavePath);
    if(QZipWriterEx(writer,dirPath,dirPath))
        ret=true;
    else
        ret=false;

    writer->close();
    delete writer;
    return  ret;
}

bool  QZipWriterEx(QZipWriter *writer, QString tmpPath, QString basePath)
{
    
    QDir dir(tmpPath);
    foreach (QFileInfo info, dir.entryInfoList())
    {
    
        if (info.fileName() == "." || info.fileName() == "..")
            continue;
        if (info.isFile())
        {
    
            QFile upfile(info.filePath());
            upfile.open(QIODevice::ReadOnly);
            QString fileName = info.filePath().mid(basePath.size()+1,info.filePath().size());
            writer->addFile(fileName,upfile.readAll());
            qDebug()<<fileName<<tmpPath<<basePath;
            upfile.close();
        }
        else if (info.isDir())
        {
    
            QZipWriterEx(writer,info.filePath(),basePath);
        }
    }
    return true;
