## 描述

在一个固定的屏幕区域中开始 GUI 控件的 GUILayout 块。

默认情况下，使用 GUILayout 创建的任何 GUI 控件都放置在屏幕的左上角。 若要在任意区域放置一系列自动布局的控件，请使用 GUILayout.BeginArea 为自动布局系统定义要使用的新区域。

另请参阅：[EndArea](https://docs.unity3d.com/cn/2019.4/ScriptReference/GUILayout.EndArea.html)

\ *说明示例区域。*

```
using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    void OnGUI()
    {
        // Starts an area to draw elements
        GUILayout.BeginArea(new Rect(10, 10, 100, 100));
        GUILayout.Button("Click me");
        GUILayout.Button("Or me");
        GUILayout.EndArea();
    }
}
```

在混合 GUILayout 代码时，该函数非常有用。它必须与 EndArea 调用配对使用。BeginArea/EndArea 不能嵌套。
