Qt实战：云曦Convert篇

(文章目录)

前言

云曦Convert软件主要采用C++、Python、Html等语言编写，以Qt5.11.1和Pycharm为编译器，运用DJANGO框架和相关QT模型与算法，以Python为后端，Qt为前端，前后端结合，为用户提供PDF文件合并，选择拆分，平均拆分以及语音导航等功能，实现用户对PDF编辑更加多样化的需求。

一、云曦Convert效果图

1. 回到首页：

在桌面上双击系统的图标就会出现以下的界面，这时候就会弹出了应用首页的界面，从这个界面中可以看到本软件所提供的相关功能和注意事项，如需在连网情况下适用等，如果不连接网络，将无法正常使用该软件，详情如下图1-1所示：

在这里插入图片描述

2. 选择拆分：

点击选择拆分按钮，将所需要拆分的文件拖入提示框中，如图2-1所示，然后输入要拆分的页数范围，点击拆分即可，详情见下图：

在这里插入图片描述

3. 平均拆分：

具体操作同选择拆分，点击平均拆分按钮，将所需要拆分的文件拖入提示框中，如图2-4所示，然后输入要平均拆分的页数，点击拆分即可，详情见下图：在这里插入图片描述

4. 文件合并：

同上述功能操作，点击文件合并按钮，将所要合并的文件拖入框中，输入合并后的文件名，点击合并，合并后打开即可，如图2-9所示。

5. 语音助手：

点击界面右上方类似于耳机的按钮，即可召唤出语音助手，来为您讲解我们的项目。如下图所示，该功能详细代码解析点击此处：在这里插入图片描述
