To test if a VisualElement is connected to a root, you can test for the panel property of this element ( null if not connected). Note: to prevent accidental usage of this property while UIElements is experimental, it’s necessary to go through the extension method GetRootVisualContainer() from the namespace. You usually add elements to an existing container object, such as EditorWindow.rootVisualContainer, to attach your UI to the panel. ConnectivityĪ newly created element is ignored until connected to the root object, called the “panel”. Note: UIElements classes are currently inside of the namespace. The VisualContainer class has several methods to work with its list of children. However, it is not strictly required to derive from any class to work with UIElements, as built-in classes should contain most of the required functionality.Ī VisualContainer object contains VisualElement child objects. VisualElement has several subclasses, including VisualContainer and specialized controls, which define additional behaviour or functionality. The VisualElement base class contains properties for styles, layout data, local transformations, event handlers, and so on. VisualElement is the common base class for all nodes of the visual tree. More info See in Glossary loading in the future. You can also create some asset types in Unity, such as an Animator Controller, an Audio Mixer or a Render Texture. An asset may come from a file created outside of Unity, such as a 3D model, an audio file or an image. These nodes are allocated on the C# heap, either manually or via asset Any media or data that can be used in your game or Project. This is a graph that can be traversed for event processing, layout and painting. The visual tree is an object graph made of lightweight nodes called “visual elements”. This was our motivation to start working on UIElements, a retained-mode UI system that opens the door to improved performance and new features such as stylesheets, dynamic/contextual event handling, accessibility and much more. While IMGUI shines in some contexts it has some serious design limitations which are affecting the productivity of everyone working on Editor features. So far the Unity editor user interface has been mostly built around the immediate mode UI (User Interface) Allows a user to interact with your application. While we appreciate any feedback, please remember that UIElements is still in active development.Īlso, please note that changes introduced in 2017.2 won’t be backported to 2017.1.* Introduction It is recommended that you look at the example project as you read through this document.ĭisclaimer: *this experimental feature is incomplete and subject to API changes. UIElements is a new experimental feature introduced in Unity 2017.1.
