JavaScript

var hSbarValue : float;

function OnGUI () {
    hSbarValue = GUILayout.HorizontalScrollbar (hSbarValue, 1.0, 0.0, 10.0);
                GUILayout.Label("This is a text that makes space");
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public float hSbarValue;
    void OnGUI() {
        hSbarValue = GUILayout.HorizontalScrollbar(hSbarValue, 1.0F, 0.0F, 10.0F);
        GUILayout.Label("This is a text that makes space");
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    public hSbarValue as single

    def OnGUI():
        hSbarValue = GUILayout.HorizontalScrollbar(hSbarValue, 1.0F, 0.0F, 10.0F)
        GUILayout.Label('This is a text that makes space')

Finding extra elements:

The styles of the buttons at then end of the scrollbar are searched for in the current skin by adding "leftbutton" and "rightbutton" to the style name. The name of the scrollbar thumb (the thing you drag) is found by appending "thumb" to the style name.var scrollPos : float = 0.5;
// This will use the following style names to determine the size / placement of the buttons
// MyScrollbarleftbutton - Name of style used for the left button.
// MyScrollbarrightbutton - Name of style used for the right button.
// MyScrollbarthumb - Name of style used for the draggable thumb.
function OnGUI() {
scrollPos = GUILayout.HorizontalScrollbar (scrollPos, 1, 0, 100, "MyScrollbar");
