dtkcompressor

dtk 文件压缩与压缩文件解压业务模块

项目介绍

dtkcompressor 是对 deepin/UOS 系统上的文件压缩与压缩文件解压业务接口的封装，为应用层开发者提供了文件的压缩、压缩文件解压的常见业务功能，其目的是在于方便第三方开发者轻松且快速的调用接口进行开发。

项目结构

对外暴露出 darchivemanager.h 这 1 个头文件。

如何使用项目

如果要使用此项目，可以阅读相关文档再参照以下示例进行调用。

使用示例

可以参考以下 Demo：

main.cpp

#include "compressortest.h"
 
#include <QApplication>
#include <QCommandLineParser>
#include <QCommandLineOption>
#include <QDir>
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    CompressorTest compressor;
 
    compressor.show();
    return app.exec();
}

compressortest.h
