用于管理 BeginScrollView/EndScrollView 的可处置的 Helper 类。
BeginScrollView 在构造时调用,EndScrollView 在处置实例时调用。 使用放置在其侧面的滚动条,滚动视图能够在屏幕上的一个较小区域内显示更大的区域。
using UnityEngine;
public class ExampleClass : MonoBehaviour { // The position of the scrolling viewport public Vector2 scrollPosition = Vector2.zero; void OnGUI() { // An absolute-positioned example: We make a scrollview that has a really large client // rect and put it in a small rect on the screen. using (var scrollScope = new GUI.ScrollViewScope(new Rect(10, 300, 100, 100), scrollPosition, new Rect(0, 0, 220, 200))) { scrollPosition = scrollScope.scrollPosition;
// Make four buttons - one in each corner. The coordinate system is defined // by the last parameter to the ScrollScope constructor. GUI.Button(new Rect(0, 0, 100, 20), "Top-left"); GUI.Button(new Rect(120, 0, 100, 20), "Top-right"); GUI.Button(new Rect(0, 180, 100, 20), "Bottom-left"); GUI.Button(new Rect(120, 180, 100, 20), "Bottom-right"); } // Now the scroll view is ended. } }
handleScrollWheel | 该滚动视图是否应处理滚轮事件。(默认值:true)。 |
scrollPosition | 修改后的 scrollPosition。将其反馈到您传入的变量中,如示例所示。 |
GUI.ScrollViewScope | 创建一个新的 ScrollViewScope 并开始相应的滚动视图。 |
