ScrollViewScope

説明

BeginScrollView / EndScrollView を管理する Disposable ヘルパークラス

自動的にレイアウトされるスクロールビューは、たとえどのようなコンテンツを持っていようとも正常に表示されるようになります。もしコンテンツがフィットしない場合は、スクロールバーが表示されます。BeginScrollView を呼び出した場合は常に最後に EndScrollView を呼び出す必要があります。


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";
    }
}
