Description 描述

Make a vertical scrollbar.

创建垂直滚动条。

A scrollbar control returns a float value that represents the position of the draggable “thumb” withtin the bar. You can use the value to adjust another GUI element to reflect the scroll position. However, most scrollable views can be handled more easily using a scroll view control.

滚动条是能通过滚动来浏览文档，大多数情况下，你可以使用scrollView代替。

JavaScript:

	var vSbarValue : float;
 
	function OnGUI () {
		vSbarValue = GUILayout.VerticalScrollbar(vSbarValue, 1.0, 10.0, 0.0);
	}

The styles of the scroll buttons at the end of the bar can be located in the current skin by adding “upbutton” and “downbutton” to the style name. The name of the scrollbar thumb (the thing you drag) is found by appending “thumb” to the style name.

滚动条两端的按钮的样式是在当前皮肤中搜索 “upbutton”和“downbutton”样式名字确定。滚动条滑块的样式是搜索 “thumb”的样式名。

JavaScript:

var scrollPos : float = 0.5;
	// This will use the following style names to determine the size / placement of the buttons
	// MyVerticalScrollbarupbutton    - Name of style used for the up button.
	// MyVerticalScrollbardownbutton - Name of style used for the down button.
	// MyVerticalScrollbarthumb         - Name of style used for the draggable thumb.
	function OnGUI() {
		scrollPos = GUILayout.HorizontalScrollbar (scrollPos, 1, 0, 100, "MyVerticalScrollbar");
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public float vSbarValue;
    void OnGUI() {
        vSbarValue = GUILayout.VerticalScrollbar(vSbarValue, 1.0F, 10.0F, 0.0F);
    }
}

The styles of the scroll buttons at the end of the bar can be located in the current skin by adding “upbutton” and “downbutton” to the style name. The name of the scrollbar thumb (the thing you drag) is found by appending “thumb” to the style name.

滚动条两端的按钮的样式是在当前皮肤中搜索 “upbutton”和“downbutton”样式名字确定。滚动条滑块的样式是搜索 “thumb”的样式名。
