Disposable helper class for managing BeginScrollView / EndScrollView.
BeginScrollView is called at construction, and EndScrollView is called when the instance is disposed. ScrollViews let you make a smaller area on-screen look 'into' a much larger area, using scrollbars placed on the sides of the ScrollView.
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 | Whether this ScrollView should handle scroll wheel events. (default: true). |
| scrollPosition | The modified scrollPosition. Feed this back into the variable you pass in, as shown in the example. |
