Description

Disposable helper class for managing BeginScrollView / EndScrollView.

Automatically laid out scrollviews will take whatever content you have inside them and display normally. If it doesn't fit, scrollbars will appear. A call to BeginScrollView must always be matched with a call to EndScrollView.


Scroll View in the Game View..

using UnityEngine;
using UnityEditor;
public class ExampleClass : MonoBehaviour
{
    // The variable to control where the scrollview 'looks' into its child elements.
    public Vector2 scrollPosition;

// The string to display inside the scrollview. 2 buttons below add & clear this string. public string longString = "This is a long-ish string";

void OnGUI() { // Begin a scroll view. All rects are calculated automatically - // it will use up any available screen space and make sure contents flow correctly. // This is kept small with the last two parameters to force scrollbars to appear. using (var scrollViewScope = new ScrollViewScope(scrollPosition, GUILayout.Width(100), GUILayout.Height(100))) { scrollPosition = scrollViewScope.scrollPosition;

// We just add a single label to go inside the scroll view. Note how the // scrollbars will work correctly with wordwrap. GUILayout.Label(longString);

// Add a button to clear the string. This is inside the scroll area, so it // will be scrolled as well. Note how the button becomes narrower to make room // for the vertical scrollbar if (GUILayout.Button("Clear")) longString = ""; }

// Now we add a button outside the scrollview - this will be shown below // the scrolling area. if (GUILayout.Button("Add More Text")) longString += "\nHere is another line"; } }
