Need upgrade guide for UIElements 2019.2.

Hi, I implemented my own Tabs control for mimicking Tabs on Unity's Lighting Window and it works well with Unity 2018.3.

Here is source code:

Code (CSharp):

1. using System.Collections.Generic;
2. using UnityEngine;
3. using UnityEngine.Experimental.UIElements;
4. using UnityEngine.Experimental.UIElements.StyleEnums;
5.  
6. namespace UIElementsEx
7. {
8.     public class Tabs : VisualElement
9.     {
10.         class Tab
11.         {
12.             public Button HeaderButton { get; set; }
13.             public VisualElement Element { get; set; }
14.  
15.             public void SetVisibility(bool value)
16.             {
17.                 if (value)
18.                 {
19.                     this.HeaderButton.style.fontStyleAndWeight = FontStyle.Italic;
20.                     this.Element.visible = true;
21.                     this.Element.style.positionType = PositionType.Relative;
22.                 }
23.                 else
24.                 {
25.                     this.HeaderButton.style.fontStyleAndWeight = FontStyle.Normal;
26.                     this.Element.visible = false;
27.                     this.Element.style.positionType = PositionType.Absolute;
28.                 }
29.             }
30.         }
31.  
32.         public override VisualElement contentContainer => base.contentContainer;
33.  
34.         VisualContainer headerContainer;
35.         VisualElement tabElementContainer;
36.         List<Tab> tabs;
37.  
38.         public Tabs()
39.         {
40.             this.headerContainer = new VisualContainer();
41.             this.headerContainer.style.flexDirection = FlexDirection.Row;
42.             this.headerContainer.style.justifyContent = Justify.Center;
43.             this.shadow.Add(this.headerContainer);
44.  
45.             this.tabElementContainer = new VisualElement();
46.             this.tabElementContainer.clippingOptions = ClippingOptions.ClipContents;
47.             CompatibilityHelper.SetFlex(this.tabElementContainer, 1.0f);
48.             this.shadow.Add(tabElementContainer);
49.  
50.             this.tabs = new List<Tab>();
51.         }
52.  
53.         public void AddTab(string text, VisualElement element)
54.         {
55.             Tab tab = new Tab();
56.             tab.Element = element;
57.             tab.HeaderButton = new Button(() =>
58.             {
59.                 foreach (Tab otherTab in this.tabs)
60.                 {
61.                     otherTab.SetVisibility(false);
62.                 }
63.  
64.                 tab.SetVisibility(true);
65.             })
66.             {
67.                 text = text,
68.             };
69.  
70.             this.tabs.Add(tab);
71.             this.headerContainer.Add(tab.HeaderButton);
72.             this.tabElementContainer.Add(tab.Element);
73.  
74.             if (this.tabs.Count == 1)
75.             {
76.                 tab.SetVisibility(true);
77.             }
78.             else
79.             {
80.                 tab.SetVisibility(false);
81.             }
82.         }
83.     }
84. }
85.  

But this code does not work with 2019.2, because the stable version of VisualElement does not have shadow, clippingOptions properties and type VisualContainer. Also AddStyleSheetPath() is missing too.

Is there any documentation for upgrading guide for stable version of UIElements?

 

Hi, Im using Unity 2018.3 and I need to have a slider that has two values instead of just one. The slider should have a min value and a max value (a range) instead of just one value in the same slider.

I saw ths slider:

https://docs.pumachen.xyz/unity-doc/ScriptReference/Experimental.UIElements.MinMaxSlider.html

But It doesnt say how to use it? How do I get this minMaxslider into my game canvas? I dont see it when i right click in the hierarchy and select UI. It only has the usual slider, button etc. How do i get the MinMaxSlider slider to show up, so that i can put on into my canvas?

Thanks

 

Im using 2018.3.14f1 doesn't seem to have it.

 

Indeed, this tool was add from 19.2
