public void BeginWindows ();

描述

标记所有弹出窗口的开始区域。

GUI.Window 在编辑器中的行为与在游戏中略有不同。在游戏中,GUI.Window 会在屏幕上弹出一个窗口。而在编辑器中, GUI.Window 会在其中一个编辑器窗口中显示一个子窗口。Begin/EndWindows 用于确定这些窗口的目标位置。 您需要为 BeginWindows/EndWindows 对中的 GUI.WindowGUILayout.Window 执行所有调用。如下所示:


Simple editor Window with a window and a button inside.

using UnityEditor;
using UnityEngine;
using System.Collections;

public class GUIWindowDemo : EditorWindow { // The position of the window public Rect windowRect = new Rect(100, 100, 200, 200); void OnGUI() { BeginWindows();

// All GUI.Window or GUILayout.Window must come inside here windowRect = GUILayout.Window(1, windowRect, DoWindow, "Hi There");

EndWindows(); }

// The window function. This works just like ingame GUI.Window void DoWindow(int unusedWindowID) { GUILayout.Button("Hi"); GUI.DragWindow(); }

// Add menu item to show this demo. [MenuItem("Test/GUIWindow Demo")] static void Init() { EditorWindow.GetWindow(typeof(GUIWindowDemo)); } }

BeginWindows/EndWindows 对的位置决定了弹出窗口的显示位置;所有窗口都会裁剪到 由 GUI.BeginGroupGUI.BeginScrollView 定义的裁剪区域。下面是该情况的一个小示例


Simple editor window with a window and a button inside using scroll bars.

using UnityEditor;
using UnityEngine;
using System.Collections;

public class GUIWindowDemo2 : EditorWindow { // The position of the window public Rect windowRect = new Rect(100, 100, 200, 200);

// Scroll position public Vector2 scrollPos = Vector2.zero;

void OnGUI() { // Set up a scroll view scrollPos = GUI.BeginScrollView(new Rect(0, 0, position.width, position.height), scrollPos, new Rect(0, 0, 1000, 1000));

// Same code as before - make a window. Only now, it's INSIDE the scrollview BeginWindows(); windowRect = GUILayout.Window(1, windowRect, DoWindow, "Hi There"); EndWindows(); // Close the scroll view GUI.EndScrollView(); }

void DoWindow(int unusedWindowID) { GUILayout.Button("Hi"); GUI.DragWindow(); }

[MenuItem("Test/GUIWindow Demo 2")] static void Init() { EditorWindow.GetWindow(typeof(GUIWindowDemo2)); } }
