#### 1.3 配置与设置
|
|||
|
|
|
|||
|
|

|
|||
|
|
// 设置加载流程
|
|||
|
|
- 语言代码规范化处理
|
|||
|
|
- 时区解析（支持 "China Standard Time" 等）
|
|||
|
|
- 颜色方案动态切换
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 2. 功能修复：白板组件
|
|||
|
|
|
|||
|
|
#### 2.1 视口布局同步问题
|
|||
|
|
|
|||
|
|
**问题描述**
|
|||
|
|
- 白板组件在附加到视觉树或大小变化时，存在视口布局同步不及时的问题
|
|||
|
|
|
|||
|
|
**解决方案**
|
|||
|
|
|
|||
|
|
1. **新增视口大小解析记录结构**
|
|||
|
|
```csharp
|
|||
|
|
internal readonly record struct WhiteboardViewportSizeResolution(
|
|||
|
|
Size Size,
|
|||
|
|
string Source,
|
|||
|
|
bool IsFallback
|
|||
|
|
);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2. **多层回退机制**
|
|||
|
|
- 第一层：使用 `ViewportRoot.Bounds.Size`
|
|||
|
|
- 第二层：使用 `CanvasBorder.Bounds.Size`
|
|||
|
|
- 第三层：使用基于单元格大小的计算值
|
|||
|
|
|
|||
|
|
3. **异步队列同步**
|
|||
|
|
```csharp
|
|||
|
|
private void QueueViewportLayoutSync(string reason)
|
|||
|
|
{
|
|||
|
|
Dispatcher.UIThread.Post(
|
|||
|
|
() => SynchronizeViewportLayout(reason),
|
|||
|
|
DispatcherPriority.Loaded);
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
4. **新增事件处理器**
|
|||
|
|
- `OnViewportRootSizeChanged`
|
|||
|
|
- `OnColorPickerPopupClosed`
|
|||
|
|
|
|||
|
|
#### 2.2 墨迹颜色透明度修复
|
|||
|
|
|
|||
|
|
**问题描述**
|
|||
|
|
- 用户选择的颜色通过颜色选择器后，透明度设置不正确
|
|||
|
|
|
|||
|
|
**修复代码**
|
|||
|
|
```csharp
|
|||
|
|
// 修复前
|
|||
|
|
InkColorPicker.Color = new Color(
|
|||
|
|
_selectedInkColor.Alpha, // 不正确的透明度来源
|
|||
|
|
_selectedInkColor.Red,
|
|||
|
|
_selectedInkColor.Green,
|
|||
|
|
_selectedInkColor.Blue);
|
|||
|
|
|
|||
|
|
// 修复后
|
|||
|
|
InkColorPicker.Color = new Color(
|
|||
|
|
byte.MaxValue, // 强制使用完全不透明
|
|||
|
|
_selectedInkColor.Red,
|
|||
|
|
_selectedInkColor.Green,
|
|||
|
|
_selectedInkColor.Blue);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
#### 2.3 墨迹输入恢复机制
|
|||
|
|
|
|||
|
|
**新增方法**
|
|||
|
|
```csharp
|
|||
|
|
private void RestoreInkInputAfterToolPopup(string reason, int attempt = 0)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**重试策略**
|
|||
|
|
- 最多尝试 3 次
|
|||
|
|
- 使用 `DispatcherPriority.Background` 延迟执行
|
|||
|
|
- 异常处理与日志记录
|
|||
|
|
|
|||
|
|
### 3. AirApp 集成更新
|
|||
|
|
|
|||
|
|

#### 3.2 世界时钟交互改进
|
|||
|
|
|
|||
|
|
**WorldClockWidget.axaml.cs 变更**
|
|||
|
|
```csharp
|
|||
|
|
// 新增日志记录
|
|||
|
|
AppLogger.Info(
|
|||
|
|
"AirAppLauncher",
|
|||
|
|
$"World clock component clicked. ComponentId='{_componentId}'; PlacementId='{_placementId}'.");
|
|||
|
|
|
|||
|
|
// 修改了方法签名
|
|||
|
|
AirAppLauncherServiceProvider.GetOrCreate().OpenWorldClock(
|
|||
|
|
_componentId, // 新增参数
|
|||
|
|
_placementId);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 4. 组件系统更新

|||
|
|
|
|||
|
|
**BuiltInComponentIds.cs**
|
|||
|
|
```csharp
|
|||
|
|
// 新增待机数字时钟组件 ID
|
|||
|
|
public const string DesktopStandbyDigitalClock = "...";
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**ComponentRegistry.cs**
|
|||
|
|
- 更新了组件注册表
|
|||
|
|
|
|||
|
|
#### 4.2 布局规则
|
|||
|
|
|
|||
|
|
**MainWindow.ComponentSystem.cs**
|
|||
|
|
```csharp
|
|||
|
|
// 新增待机数字时钟的缩放规则（与现有世界时钟一致）
|
|||
|
|
if (string.Equals(componentId, BuiltInComponentIds.DesktopStandbyDigitalClock, ...))
|
|||
|
|
{
|
|||
|
|
// 保持 2:1 宽高比
|
|||
|
|
return SnapSpanToScaleRules(span,
|
|||
|
|
new ComponentScaleRule(WidthUnit: 2, HeightUnit: 1, MinScale: 2));
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
#### 4.3 删除旧代码
|
|||
|
|

|||
|
|
|
|||
|
|
### 5. 测试覆盖
|
|||
|
|
|
|||
|
|

## 代码审查要点
|
|||
|
|
|
|||
|
|
### ✅ 优点
|
|||
|
|
|
|||
|
|
1. **良好的日志记录**
|
|||
|
|
- 使用 `AppLogger.Info` 记录关键操作
|
|||
|
|
- 包含丰富的上下文信息（ComponentId, PlacementId 等）
|
|||
|
|
|
|||
|
|
2. **完善的错误处理**
|
|||
|
|
- 白板墨迹恢复机制包含重试逻辑
|
|||
|
|
- 异常捕获和降级处理
|
|||
|
|
|
|||
|
|
3. **响应式设计**
|
|||
|
|

|
|||
|
|
- 主题自适应支持
|
|||
|
|
|
|||
|
|
4. **向后兼容性**
|
|||
|
|
- 保留了现有世界时钟的布局规则
|
|||
|
|
|
|||
|
|
### ⚠️ 建议关注
|
|||
|
|
|
|||
|
|
1. **视口同步频率**
|
|||
|
|
- `DispatcherPriority.Loaded` 可能导致频繁重绘
|
|||
|
|
- 建议监控性能影响
|
|||
|
|
|
|||
|
|
2. **颜色透明度处理**
|
|||
|
|
- 修改为强制不透明可能会影响某些使用场景
|
|||
|
|
- 建议添加配置选项
|
|||
|
|
|
|||
|
|
3. **时区解析**
|
|||
|
|
- 使用 "China Standard Time" 作为默认时区
|
|||
|
|
- 考虑添加用户可配置的默认时区
|
|||
|
|
|
|||
|
|
4. **测试覆盖**
|
|||
|
|
- 新增测试文件内容需要进一步验证
|
|||
|
|
- 建议添加集成测试
