== 实际案例 ==
=== GUI框架中的使用 ===
<mermaid>
classDiagram
    class Widget
    class Clickable {
        <<mixin>>
        +onClick()
    }
    class Draggable {
        <<mixin>>
        +onDrag()
    }
    Widget <|-- Button
    Clickable <|-- Button
    Widget <|-- Panel
    Draggable <|-- Panel
</mermaid>

=== 游戏开发示例 ===
<syntaxhighlight lang="cpp">
template<typename T>
class RenderableMixin {
public:
    void render() const {
        const auto& self = static_cast<const T&>(*this);
        // 调用具体类型的渲染逻辑
        self.drawMesh();
    }
};

class GameObject {
    // 基础属性...
};

class Enemy : public GameObject, public RenderableMixin<Enemy> {
public:
    void drawMesh() const { /* 渲染敌人模型 */ }
};
</syntaxhighlight>
