一直想通過切換按鈕實(shí)現(xiàn)編輯器上某些部分顯示或者隱藏的功能。今天無意中實(shí)現(xiàn)了這個(gè)功能。原理很簡(jiǎn)單，編輯器面板上看到的都是繪制上去的，那么只要在特定時(shí)候不繪制就實(shí)現(xiàn)了這功能。

using UnityEditor;
using UnityEngine;

public class TestEditorWindow : EditorWindow
{
    [MenuItem ("EditorWindow/TestEditorWindow")]
    static void Init ()
    {
        EditorWindow.GetWindow<TestEditorWindow> ();
    }

    string mNotification = "通知消息";
    bool mNotificationShow = false;

    void OnGUI ()
    {
        #region 檢測(cè)鼠標(biāo)事件
//      wantsMouseMove = EditorGUILayout.Toggle ("Recive Movment : ", wantsMouseMove);
        wantsMouseMove = EditorGUILayout.BeginToggleGroup ("鼠標(biāo)移動(dòng)", wantsMouseMove);
        if (wantsMouseMove) {
            EditorGUILayout.Vector2Field ("    鼠標(biāo)位置", Event.current.mousePosition);
            if (Event.current.type == EventType.MouseMove && wantsMouseMove) {
                Repaint ();
            }
        }
        EditorGUILayout.EndToggleGroup ();
        #endregion

        #region 顯示通知消息
        mNotificationShow = EditorGUILayout.BeginToggleGroup ("通知消息", mNotificationShow);
        if (mNotificationShow) {
            mNotification = EditorGUILayout.TextField (mNotification);
            if (GUILayout.Button ("顯示消息")) {
                this.ShowNotification (new GUIContent (mNotification));
            }
            if (GUILayout.Button ("隱藏消息")) {
                RemoveNotification ();
            }
        }
        EditorGUILayout.EndToggleGroup ();
        #endregion
    }
}

效果如下:
