+# [1008] 统一模板打开器重构
+
+## 1 相关文档
+- [dddd.md](dddd.md) - 任务文档模板
+
+## 2 任务相关的代码文件
+- `src/Plugins/Qt/QTMTemplateOpener.hpp`
+- `src/Plugins/Qt/QTMTemplateOpener.cpp`
+- `src/Plugins/Qt/QTMHomePage.cpp`
+- `src/Plugins/Qt/QTMHomePage.hpp`
+- `src/Plugins/Qt/QTMTemplatePage.cpp`
+- `src/Plugins/Qt/QTMTemplatePage.hpp`
+- `src/Plugins/Qt/qt_template_utils.hpp`
+- `src/Plugins/Qt/qt_template_utils.cpp`
+
+## 3 如何测试
+
+### 非确定性测试（文档验证）
+
+启动应用并验证以下功能：
+1. HomePage 点击模板卡片能否正常打开模板
+2. TemplatePage 预览后点击打开能否正常工作
+3. 本地模板和远程模板的打开流程是否正确
+4. 下载进度对话框是否正常显示
+5. 取消下载后是否无错误提示
+
+
+## 4 如何提交
+
+提交前执行以下最少步骤：
+
+```bash
+# 代码格式化
+./bin/format
+
+# 编译验证
+xmake build
+```
+
+## 5 What
+
+将 `QTMHomePage` 和 `QTMTemplatePage` 中分散的模板打开逻辑抽取为独立的 `QTMTemplateOpener` 类，实现统一的模板打开流程。
+
+1. 新增 `QTMTemplateOpener` 类（`QTMTemplateOpener.hpp/cpp`）
+   - 封装本地模板打开逻辑：复制到 Documents 并加载
+   - 封装远程模板下载逻辑：显示进度对话框、同步下载、错误处理
+   - 提供信号：`completed`、`failed`、`downloadProgress`
+   
+2. 重构 `QTMHomePage`
+   - 删除 `createDocumentFromTemplate` 方法
+   - 使用 `QTMTemplateOpener` 打开模板
+   
+3. 重构 `QTMTemplatePage`
+   - 删除重复的模板打开代码
+   - 使用 `QTMTemplateOpener` 打开模板
+
+4. 清理冗余 include
+   - 从 `QTMHomePage.cpp` 和 `QTMTemplatePage.cpp` 中移除不再需要的 `qt_template_utils.hpp`
+
+## 6 Why
+
+`QTMHomePage` 和 `QTMTemplatePage` 中各自维护了一套几乎相同的模板打开逻辑，存在以下问题：
+
+- **代码重复**：下载进度对话框、错误处理、本地/远程判断逻辑在两个类中重复实现
+- **维护困难**：修改模板打开流程需要在两个地方同步修改
+- **职责不单一**：页面类既负责 UI 展示又负责业务逻辑
+
+通过抽取 `QTMTemplateOpener` 类，实现单一职责原则，提高代码复用性和可维护性。
+
+## 7 How
+
+### 7.1 设计思路
+
+采用 QObject 子类封装模板打开逻辑，通过信号通知调用方结果：
+
+```
+QTMTemplateOpener (QObject)
+├── openTemplate(templateId)          // 主入口
+├── isAvailableLocally(templateId)    // 本地检查
+├── openLocalTemplate_()              // 本地打开（私有）
+├── startDownload_()                  // 远程下载（私有）
+└── 信号: completed / failed / downloadProgress
+```
+
+### 7.2 同步下载处理
+
+由于模板打开需要阻塞等待下载完成（同时保持 UI 响应），采用 `QProgressDialog` + `downloadTemplateSync` 的同步风格：
+
+1. 显示模态进度对话框
+2. 调用 `TemplateManager::downloadTemplateSync` 阻塞下载
+3. 通过信号更新进度对话框
+4. 下载完成后关闭对话框并打开模板
+
+### 7.3 错误处理策略
+
+- 本地模板不存在 → 显示错误 Toast，发射 `failed` 信号
+- 下载失败 → 显示错误 Toast（非用户取消时），发射 `failed` 信号
+- 用户取消下载 → 静默失败，发射空的 `failed` 信号
+
+### 7.4 使用方式
+
+```cpp
+QTMTemplateOpener opener(this);
+opener.openTemplate("template-id");
+```
+
+调用方可以选择连接信号处理结果，也可以直接调用（同步风格，结果在返回前已确定）。
