```cpp
|
|||
|
|
SceneViewPanel();
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 作用
|
|||
|
|
|
|||
|
|
创建标题固定为 `"Scene"` 的 Scene View 面板。
|
|||
|
|
|
|||
|
|
## 当前实现行为
|
|||
|
|
|
|||
|
|
当前构造函数非常薄：
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
SceneViewPanel::SceneViewPanel() : Panel("Scene") {}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
这意味着它只做一件事：
|
|||
|
|
|
|||
|
|
- 通过基类 `Panel` 把窗口标题初始化成 `"Scene"`
|
|||
|
|
|
|||
|
|
其余运行期状态都依赖成员默认值完成初始化，例如：
|
|||
|
|
|
|||
|
|
- `m_toolMode = Move`
|
|||
|
|
- `m_pivotMode = Pivot`
|
|||
|
|
- `m_transformSpaceMode = Global`
|
|||
|
|
- 三套 gizmo 对象
|
|||
|
|
- look / pan 拖拽标记
|
|||
|
|
|
|||
|
|
## 设计含义
|
|||
|
|
|
|||
|
|
这类构造方式说明 `SceneViewPanel` 的真正初始化成本不在 constructor，而在每帧 `Render()` 里对上下文、视口宿主和当前选择状态的编排。
