public ref T GetOrAddComponent<T>() where T : struct, IVisualElementComponent
Returns
Type | Description |
|---|---|
| T | A reference to the live component data. Like VisualElement.GetComponent, the reference is valid until a component is added to or removed from this element. |
Remarks
When the component is already attached, this method behaves exactly like VisualElement.GetComponent and the component data is not changed. When it is not attached, a new component is created and added the same way as VisualElement.AddComponent. The new component is created with the type's UxmlCreateInstanceMethodAttribute method when the type has one, otherwise with default values.
