问题遇到的现象和发生背景
需要构建一个小程序用于pdf文件模糊搜索，搜到的结果合并成一个pdf文件。
窗的左边做搜索以及项目复选框（用户可直接勾选），勾选/搜索出的结果在窗的右边直接生成pdf合并版文件，用户可直接下载。
问题相关代码，请勿粘贴截图
代码请见下方
运行结果及报错内容
目前运行结果为小程序窗口的弹出，左侧内容设计了几个项目类别及复选框，尚未实现用户可直接勾选触发后续操作。
我的解答思路和尝试过的方法
使用tkinter designer直接生成了小程序布局的代码。
我想要达到的结果
用户点击左侧窗口的项目类别可直接查看相关文件分类，右侧窗口能够生成用户所选中pdf文件的合并版并可直接下载。
