ScrollViewScope

설명

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";
    }
}
