PySimpleGUI搜索GUI Listbox右键Open/Save事件触发报错求助

已定位的错误点 #

• 语法错误：主事件循环while True代码块缩进错误，多了前置空格，运行直接报错
• 事件逻辑错误：右键菜单的Open/Save选项触发的事件值就是字符串Open/Save，原代码把对应逻辑写在了if event == '-RESULTS-'分支下，永远无法触发
• 路径存储错误：搜索结果只存储了文件名，没有拼接完整路径，后续打开/保存操作无法定位到真实文件
• 计数逻辑错误：仅在CONTAINS匹配模式下会累加匹配数matches，其余两种匹配模式无计数，搜索结果统计不准
• 空函数问题：open_file/save_file无实现逻辑，无法完成对应操作

修复后完整可运行代码 #

功能说明 #

• 修复了所有语法和逻辑错误，可直接运行
• 支持多选文件后右键打开、右键保存，也可点击下载按钮批量保存
• 搜索过程放到子线程运行，不会卡住GUI界面
• 增加了操作结果提示，所有操作完成后都会弹出统计结果
• 搜索完成弹窗会显示扫描总文件数和匹配文件数
• 打开/保存都增加了异常处理，不会因为单个文件报错导致程序崩溃
