Unity Inspector Custom Tabbar

效果类似于 Terrain Inspector 的顶层 Tabbar，不过按钮之间有间距，这个如果需要完全一样也可以改 GUIStyle 实现。

public class JZSpaceShipControllerEditor : Editor
	{
		/// <summary>
		/// 飞船控制器编辑器 Tab 类别枚举
		/// </summary>
		enum JZSpaceShipControllerEditorTab
		{
			General,
			Control,
			Weapon
		};

		/// <summary>
		/// Tab Button Inactive State 样式
		/// </summary>
		private static GUIStyle ToggleButtonStyleNormal = null;
		/// <summary>
		/// Tab Button Active State 样式
		/// </summary>
		private static GUIStyle ToggleButtonStyleToggled = null;
		/// <summary>
		/// 飞船控制器编辑器当前选中的 Tab
		/// </summary>
		private JZSpaceShipControllerEditorTab currentTab;

		public override void OnInspectorGUI()
		{
			JZSpaceShipController spaceShipController =
				(JZSpaceShipController) target;

			if (ToggleButtonStyleNormal == null || ToggleButtonStyleToggled == null)
			{
				ToggleButtonStyleNormal = "Button";
				ToggleButtonStyleToggled = new GUIStyle(ToggleButtonStyleNormal);
				ToggleButtonStyleToggled.normal.background = ToggleButtonStyleToggled.active.background;
			}

			GUILayout.BeginHorizontal();
			foreach (JZSpaceShipControllerEditorTab tab in Enum.GetValues(typeof(JZSpaceShipControllerEditorTab)))
			{
				if (GUILayout.Button(tab.ToString(),
					currentTab == tab ? ToggleButtonStyleToggled : ToggleButtonStyleNormal))
				{
					currentTab = tab;
				}
			}
			GUILayout.EndHorizontal();

			switch (currentTab)
			{
				case JZSpaceShipControllerEditorTab.General:
				{
					EditorGUILayout.HelpBox("Space Ship Controller",MessageType.Info);
				}
					break;
				case JZSpaceShipControllerEditorTab.Control:
				{
				}
					break;
				case JZSpaceShipControllerEditorTab.Weapon:
				{
				}
					break;
			}
		}
