实现DropDown

传统的gui in Editor并没有editor

或者有我不知道

但确实明显没有

但是有menu

左右布局实现

实现不了docker，就将就用用

void OnGUI()
{
    if (EditorGUILayout.DropdownButton(new GUIContent("11"), FocusType.Passive))
        {
            Debug.LogError("fff");
            GenericMenu menu = new GenericMenu();

            // forward slashes nest menu items under submenus
            AddMenuItemForColor(menu, "RGB/Red", Color.red);
            AddMenuItemForColor(menu, "RGB/Green", Color.green);
            AddMenuItemForColor(menu, "RGB/Blue", Color.blue);
            
            menu.AddSeparator("");

            AddMenuItemForColor(menu, "White", Color.white);

            // display the menu
            menu.ShowAsContext();
        }


}
    void AddMenuItemForColor(GenericMenu menu, string menuPath, Color color)
    {
        // the menu item is marked as selected if it matches the current value of m_Color
        menu.AddItem(new GUIContent(menuPath), m_Color.Equals(color), OnColorSelected, color);
    }
    // the GenericMenu.MenuFunction2 event handler for when a menu item is selected
    void OnColorSelected(object color)
    {
        m_Color = (Color)color;
    }

gui rect定位的秘密

关键还是Style,某个小弟的分析给了我启发

原来搞这么多年，都没搞懂

label的style简单，是GUI.sytle.label

  public class GUILayout
  {
    /// <summary>
    ///   <para>Make an auto-layout label.</para>
    /// </summary>
    /// <param name="text">Text to display on the label.</param>
    /// <param name="image">Texture to display on the label.</param>
    /// <param name="content">Text, image and tooltip for this label.</param>
    /// <param name="style">The style to use. If left out, the label style from the current GUISkin is used.</param>
    /// <param name="options">An optional list of layout options that specify extra layouting properties. Any values passed in here will override settings defined by the style.&lt;br&gt;
    /// See Also: GUILayout.Width, GUILayout.Height, GUILayout.MinWidth, GUILayout.MaxWidth, GUILayout.MinHeight,
    /// GUILayout.MaxHeight, GUILayout.ExpandWidth, GUILayout.ExpandHeight.</param>
    public static void Label(Texture image, params GUILayoutOption[] options)
    {
      GUILayout.DoLabel(GUIContent.Temp(image), GUI.skin.label, options);
    }

objectField的style是.layerMaskField

  /// <summary>
    ///   <para>Get a rect for an Editor control.</para>
    /// </summary>
    /// <param name="hasLabel">Optional boolean to specify if the control has a label. Default is true.</param>
    /// <param name="height">The height in pixels of the control. Default is EditorGUIUtility.singleLineHeight.</param>
    /// <param name="style">Optional GUIStyle to use for the control.</param>
    /// <param name="options">An optional list of layout options that specify extra layout properties. Any values passed in here will override settings defined by the style.
    /// See Also: GUILayout.Width, GUILayout.Height, GUILayout.MinWidth, GUILayout.MaxWidth, GUILayout.MinHeight,
    /// GUILayout.MaxHeight, GUILayout.ExpandWidth, GUILayout.ExpandHeight.</param>
    public static Rect GetControlRect(
      bool hasLabel,
      float height,
      params GUILayoutOption[] options)
    {
      return EditorGUILayout.GetControlRect(hasLabel, height, EditorStyles.layerMaskField, options);
    }
