unity 扩展编辑器二 新建窗体

using UnityEngine;
using UnityEditor;
public class MyEditor : EditorWindow 
{
 
    [MenuItem ("GameObject/window")]
    static void AddWindow ()
	{       
		//创建窗口
		Rect  wr = new Rect (0,0,500,500);
        MyEditor window = (MyEditor)EditorWindow.GetWindowWithRect (typeof (MyEditor),wr,true,"widow name");	
		window.Show();
 
    }
}

EditorWindow.GetWindowWithRect() 和 EditorWindow.GetWindow()都可以创建一个窗口。前者可以规定窗口的区域，后者可通过鼠标动态的延伸窗口。参数1表示窗口的对象，参数2表示窗口的区域，参数3表示窗口类型true表示窗口不会被别的窗口覆盖，参数4表示窗口的名称。

public class MyEditor : EditorWindow {

	[MenuItem("GameObject/window")]
	static void AddWindow()
	{
		//创建窗口
		Rect wr=new Rect(0,0,500,500);
		MyEditor window =(MyEditor)EditorWindow.GetWindowWithRect(typeof(MyEditor),wr,true,"window name");
		window.Show();
	}

	//输入文字到内容
	private string text;

	//选择贴图的对象
	private Texture texture;


	public void Awake()
	{
		//在资源中读取一站贴图
		texture = Resources.Load("1") as Texture;
	}

	void OnGUI()
	{
		//输入框控件
		text = EditorGUILayout.TextField("输入文字：",text);

		if(GUILayout.Button("打开通知",GUILayout.Width(200)))
		{
			//打开通知栏
			this.ShowNotification(new GUIContent("this is a notification"));
		}

		if(GUILayout.Button("关闭通知",GUILayout.Width(200)))
		{
			//关闭通知栏
			this.RemoveNotification();
		}

		//文本框显示鼠标再窗口的位置
		EditorGUILayout.LabelField("鼠标在窗口的位置",Event.current.mousePosition.ToString());

		//选择贴图
		texture = EditorGUILayout.ObjectField( "添加贴图" , texture , typeof ( Texture ) , true ) as Texture;


		if(GUILayout.Button("关闭窗口"))
		{
			//关闭窗口
			this.Close();
		}
