Best Practices

最佳实践

Choose the Right Mode: Use Tabbed mode for document-centric apps, Normal mode when tabs are secondary navigation
Enable Drag-Drop: Set
```
AllowDragDrop="True"
```
for intuitive reordering and tear-off functionality
Handle NewTabRequested: Always implement this event handler when
```
EnableNewTabButton="True"
```
MVVM Pattern: Use
```
ItemsSource
```
binding for data-driven scenarios with clean separation of concerns
Validate Merges: Use
```
PreviewTabMerge
```
to control which tabs can be moved between windows
Keyboard Support: Document keyboard shortcuts for users (Ctrl+Tab, Ctrl+Shift+Tab, Ctrl+T)
Visual Feedback: Ensure drag-drop operations have clear visual indicators for user guidance

选择合适模式： 文档中心类应用使用Tabbed模式，标签为次要导航时使用Normal模式
启用拖拽功能： 设置
```
AllowDragDrop="True"
```
以支持直观的重排与拖离功能
处理NewTabRequested事件： 当设置
```
EnableNewTabButton="True"
```
时，务必实现该事件处理程序
采用MVVM模式： 数据驱动场景使用
```
ItemsSource
```
绑定，实现关注点分离
验证合并操作： 使用
```
PreviewTabMerge
```
控制可跨窗口移动的标签范围
支持键盘快捷键： 为用户提供键盘快捷键文档（Ctrl+Tab、Ctrl+Shift+Tab、Ctrl+T）
提供视觉反馈： 确保拖拽操作有清晰的视觉提示，引导用户操作
