EdirotGUILayout / EdirotGUI 方法的简单使用

EdirotGUILayout / EdirotGUI 方法的简单使用

1:编写一个EditorWindow并展示一个label

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

        void OnGUI()
        {
            EditorGUILayout.LabelField("Example Label");
        }
    }

2:Toggle

  bool showBtn = true;
  void OnGUI()
  {
      showBtn = EditorGUILayout.Toggle("Show Button",showBtn);
      if(showBtn){  //开关点开
          if(GUILayout.Button("Close")){ //绘制按钮
              this.Close(); //关闭面板
          }
      }
  }

  void OnGUI()
  {
      EditorGUI.BeginChangeCheck();

      toggleValue = EditorGUILayout.ToggleLeft("Toggle", toggleValue);

      //toggleValue 值每次改变时,EditorGUI.EndChangeCheck()都返回true
      if (EditorGUI.EndChangeCheck())
      {
          if (toggleValue)
          {
              Debug.Log("toggleValue:" + toggleValue);
          }
          else
          {
              Debug.Log("toggleValue:" + toggleValue);
          }
      }
      bool on = GUILayout.Toggle(on, on ? "on" : "off", "button");
  }

    bool toggleValue;

    Stack<bool> stack = new Stack<bool> ();

    void OnGUI ()
    {
        {
            stack.Push (GUI.changed);
            GUI.changed = false;
        }
        toggleValue = EditorGUILayout.ToggleLeft ("Toggle", toggleValue);
        {
            bool changed = GUI.changed;

            GUI.changed |= stack.Pop ();
        }
        if (changed) {
            Debug.Log ("toggleValue");
        }
    }

    bool toggleValue;

    Stack<bool> stack = new Stack<bool>();

    void OnGUI()
    {
        stack.Push(GUI.changed);
        GUI.changed = false;

        toggleValue = EditorGUILayout.ToggleLeft("Toggle", toggleValue);

        bool changed = GUI.changed;
        Debug.Log("changed:" + changed);

        GUI.changed |= stack.Pop();

        if (changed)
        {
            Debug.Log("toggleValue");
        }
    }

    private bool groupEnabled; //区域开关
    void OnGUI()
    {
        groupEnabled = EditorGUILayout.BeginToggleGroup("Optional Settings", groupEnabled);
        ///其他编辑代码
        EditorGUILayout.EndToggleGroup();
    }

3:ObjectField

  void OnGUI ()
  {
      EditorGUILayout.ObjectField (null, typeof(Object), false);

      EditorGUILayout.ObjectField (null, typeof(Material), false);

      EditorGUILayout.ObjectField (null, typeof(AudioClip), false);

      var options = new []{GUILayout.Width (64), GUILayout.Height (64)};

      EditorGUILayout.ObjectField (null, typeof(Texture), false, options);

      EditorGUILayout.ObjectField (null, typeof(Sprite), false, options);
  }

4:EditorGUI.MultiFloatField

  float[] numbers = new float[] {
      0,
      1,
      2
  };

  GUIContent[] contents = new GUIContent[] {
      new GUIContent ("X"),
      new GUIContent ("Y"),
      new GUIContent ("Z")
  };

  void OnGUI()
  {
      EditorGUI.MultiFloatField(
          new Rect(30, 30, 200, EditorGUIUtility.singleLineHeight),
          new GUIContent("Label"),
          contents,
          numbers);
  }

5: EditorGUI.indentLevel 层级表现

void OnGUI ()
{
  EditorGUILayout.LabelField ("Parent");

  EditorGUI.indentLevel++;

  EditorGUILayout.LabelField ("Child");
  EditorGUILayout.LabelField ("Child");

  EditorGUI.indentLevel--;

  EditorGUILayout.LabelField ("Parent");

  EditorGUI.indentLevel++;

  EditorGUILayout.LabelField ("Child");
}

6:EditorGUILayout.Knob,一个圈圈表现

  float angle = 270;

  void OnGUI()
  {
      angle = EditorGUILayout.Knob(Vector2.one * 64,
          angle, 0, 360, "度", Color.gray, Color.red, true);
  }

7:Scope排版

  public class HorizontalScope : GUI.Scope
  {

      public HorizontalScope()
      {
          EditorGUILayout.BeginHorizontal();
      }

      protected override void CloseScope()
      {
          EditorGUILayout.EndHorizontal();
      }        
  }

  void OnGUI()
  {

      using (new EditorGUILayout.HorizontalScope())
      {
          GUILayout.Button("Button1");
          GUILayout.Button("Button2");
      }
      using (new EditorGUILayout.HorizontalScope ()) {
          one = GUILayout.Toggle (one, "1", EditorStyles.miniButtonLeft);
          two = GUILayout.Toggle (two, "2", EditorStyles.miniButtonMid);
          three = GUILayout.Toggle (three, "3", EditorStyles.miniButtonRight);
      }     
  }

{
    selected = GUILayout.Toolbar(selected, new string[] { "1", "2", "3" });
    selected = GUILayout.Toolbar(selected, new string[] { "1", "2", "3" }, EditorStyles.toolbarButton);
    selected = GUILayout.SelectionGrid(selected,new string[] { "1", "2", "3" }, 1, "PreferencesKeysElement");
}

    if (showBtn)
    {
        EditorGUILayout.LabelField("密码:", text);
    }
}

* 11:Slider 滑动条 IntSlider 整数滑动条 MinMaxSlider 最小最大滑动条

float maxLimit = 20.0f;
void OnGUI()
{
    EditorGUILayout.LabelField("Min Val:", minVal.ToString());
    EditorGUILayout.LabelField("Max Val:", maxVal.ToString());
    EditorGUILayout.MinMaxSlider(ref minVal,ref  maxVal, minLimit, maxLimit);

}

* 12:Popup弹出选择菜单

    CUBE = 0,
    SPHERE = 1,
    PLANE = 2
}
public class myEditor3 : EditorWindow {
    OPTIONS op=OPTIONS.CUBE;
    [MenuItem("cayman/tempShow")]
    static void newWelcome()
    {
        EditorWindow.GetWindow(typeof(myEditor3), true, "Eam");
    }
    void OnGUI()
    {
    op = (OPTIONS)EditorGUILayout.EnumPopup("Primitive to create:", op)  ;
    }
}

int selectedSize = 1;
string[] names = { "Normal","Double","Quadruple"};
int[] sizes = { 1,2,4};
void OnGUI()
{
    selectedSize = EditorGUILayout.IntPopup("Resize Scale: ", selectedSize, names, sizes);
    if (GUILayout.Button("Scale"))
        ReScale();
}
void ReScale()
{
    if (Selection.activeTransform)
        Selection.activeTransform.localScale =new Vector3(selectedSize, selectedSize, selectedSize);
    else Debug.LogError("No Object selected, please select an object to scale.");

    Rect rect = EditorGUILayout.GetControlRect(GUILayout.Width(600));
    //将上面的框作为文本输入框  
    path = EditorGUI.TextField(rect, path);

    //如果鼠标正在拖拽中或拖拽结束时，并且鼠标所在位置在文本输入框内  
    if ((Event.current.type == EventType.DragUpdated
      || Event.current.type == EventType.DragExited)
      && rect.Contains(Event.current.mousePosition))
    {
        //改变鼠标的外表  
        DragAndDrop.visualMode = DragAndDropVisualMode.Generic;
        if (DragAndDrop.paths != null && DragAndDrop.paths.Length > 0)
