+2. 在 `MainWindow.h` 中添加图表成员变量 +3. 在 `MainWindow.cpp` 中实现图表绘制逻辑 + +### 自定义样式 + +可以在 `MainWindow::setupUI()` 中修改界面样式： + +```cpp +// 修改表格样式 +m_tableWidget->setStyleSheet("QTableWidget { background-color: #f0f0f0; }"); + +// 修改按钮样式 +m_refreshButton->setStyleSheet("QPushButton { background-color: #4CAF50; color: white; }"); +``` + +## 🐛 故障排除 + +### 问题1: 找不到CSV文件 + +**现象**: 提示"找不到考勤数据文件" + +**解决方案**: +1. 确认CSV文件路径是否正确 +2. 检查 `../server/attendance_database.csv` 是否存在 +3. 手动修改 `getDefaultCsvPath()` 函数中的路径 + +### 问题2: Qt Charts模块找不到 + +**现象**: 编译错误 `Could not find a package configuration file provided by "Qt5Charts"` + +**解决方案**: +```bash +# Ubuntu/Debian +sudo apt-get install libqt5charts5-dev + +# 或从CMakeLists.txt中移除Charts（如果不需要图表功能） +find_package(Qt5 REQUIRED COMPONENTS Core Widgets) # 删除Charts +``` + +### 问题3: 自动刷新不工作 + +**现象**: 数据不会自动更新 + +**解决方案**: +1. 检查文件权限，确保程序有读取权限 +2. 某些网络驱动器可能不支持文件监视 +3. 手动点击"刷新数据"按钮 + +## 📈 性能优化 + +- 使用 `QVector` 存储数据，高效访问 +- 表格按需更新，避免全量刷新 +- 文件监视避免频繁读取磁盘 +- 筛选操作在内存中进行，速度快 + +## 🎓 扩展功能建议 + +- [ ] **图表统计** - 添加签到趋势图、人员统计图 +- [ ] **数据库支持** - 支持SQLite/MySQL数据库 +- [ ] **Excel导出** - 使用QXlsx库导出真正的Excel格式 +- [ ] **打印功能** - 支持打印考勤报表 +- [ ] **多语言支持** - 中英文切换 +- [ ] **主题切换** - 明暗主题切换 + +## 📄 许可证 + +本项目与主项目使用相同的许可证，仅供学习和研究使用。 + +## 🙏 致谢 + +感谢使用本考勤系统Qt查看器！ + +--- + +**开始使用**： +1. 确保服务器端已生成 `attendance_database.csv` 文件 +2.
