![]() ![]() In Unity, select PlanetsListView.cs in the Project window, and then drag PlanetsListView.uxml into the Uxml field in the Inspector.įrom the menu, select Planets > Standard List to see a list of planets. ListView.bindItem = (VisualElement element, int index) => Set ListView.bindItem to bind an initialized entry to a data item. Set ListView.makeItem to initialize each entry in the list. Set emsSource to populate the data in the list. Public class PlanetsListView : PlanetsWindow Replace the contents of PlanetsListView.cs with the following: using UnityEditor Your PlanetsListView.uxml should look like the following: In the Inspector window, set Fixed Item Height to 20. Select the ListView control in the Hierarchy window. In the Hierarchy window, delete the Label control and add the ListView control. This creates two files: PlanetsListView.uxml and PlanetsListView.cs.ĭouble-click PlanetsListView.uxml to open it in the UI Builder. In the C# box, enter PlanetsListView and clear the USS checkbox. Select Create > UI Toolkit > Editor Window. Finally, reference the UXML file to the C# script. Then, create a custom Editor window with the ListView and define where to get data for the list in a C# script. To create a list view, first use the UI builder to create a ListView UI control. Roots.Add(new TreeViewItemData(id++, group, planetsInGroup)) PlanetsInGroup.Add(new TreeViewItemData(id++, planet)) Var roots = new List>(planetGroups.Count) Needed for TreeView and MultiColumnTreeView. Expresses planet data as a list of TreeViewItemData objects. Needed for ListView and MultiColumnListView. Expresses planet data as a list of the planets themselves.

Public Planet(string name, bool populated = false) Nested class that represents a planet. Nested interface that can be either a single planet or a group of planets. Public class PlanetsWindow : EditorWindow Base class for all windows that display planet information. Replace the contents of PlanetsWindow.cs with the following: using In the Editor folder, create a C# script named PlanetsWindow.cs. In your Project window, create a folder named Editor. Before you start, get familiar with the following:Ĭreate data in a C# script that’s made up of two groups of planets and the root nodes for the tree view.Ĭreate a project in Unity with any template. This guide is for developers familiar with the Unity Editor, UI Toolkit, and C# scripting. You can find the completed files that this example creates in this GitHub repository. A tree view of planets with two columns.This example creates four Editor windows that display the following: You configure the structure of lists and trees with UXML and then dynamically populate them in your C# script. This example demonstrates how to create list and tree views inside a custom Editor window. You can use UI Toolkit to create list and tree views inside a custom Editor window or runtime. color_selected ¶īackground color of the node when the node is selected.List and tree views are common features in UI design.
