ScrollViewScope 滚动范围

class in UnityEngine

Description 描述

Disposable helper class for managing BeginScrollView / EndScrollView.

管理BeginScrollView / EndScrollView的可支配助手类。

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.

自动布局滚动范围将会获取它们内部的内容并正常显示。如果不合适,滚动条将会出现。BeginScrollView必须总是匹配EndScrollView。

JavaScript:

#pragma strict

public var scrollPosition: Vector2;

public var longString: String = "This is a long-ish string";

function OnGUI() {

	var scrollViewScope: var = new ScrollViewScope(scrollPosition, GUILayout.Width(100), GUILayout.Height(100));

	{

		scrollPosition = scrollViewScope.scrollPosition;

		// scrollbars will work correctly with wordwrap.

		GUILayout.Label(longString);

		// for the vertical scrollbar

		if (GUILayout.Button("Clear"))

			longString = "";

	}

	// the scrolling area.

	if (GUILayout.Button("Add More Text"))

		longString += "\nHere is another line";

}

C#:

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 =  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";

 

	}

}
