QT6 写一个诗词鉴赏、朗诵、阅读程序（智谱清言AI赏析接口）

实现了一个基于Qt框架的古诗词浏览应用。主要功能包括：通过PoemDatabase类管理诗词数据，首次运行时自动检查并导入Chinese-poetry目录中的数据；提供朝代筛选、关键词搜索和诗词浏览功能；双击诗词可查看详情和朗诵；界面采用qss样式表实现古风设计。核心类包括MainWindow、PoemDetailDialog和PoemPlayer，实现了数据管理、界面交互和语音朗诵功能。代码结构清晰，包含数据加载、UI初始化、样式应用和事件处理等模块。

使用网络上Chinese-poetry数据，github上有，gitee也有

以下是mainwindow.cpp
