| tabIndex | An integer used to sort focusables in the focus ring. Must be greater than or equal to zero. |
| childCount | Number of child elements in this object's contentContainer. |
| contentContainer | Child elements are added to it, usually this is the same as the element itself. |
| contentRect | The rectangle of the content area of the element, in the local space of the element. |
| customStyle | The custom style properties accessor of a VisualElement (Read Only). |
| enabledInHierarchy | Returns true if the VisualElement is enabled in its own hierarchy. |

| experimental | Returns the UIElements experimental interfaces. |
| generateVisualContent | Called when the VisualElement visual contents need to be (re)generated. |
| hierarchy | Access to this element physical hierarchy |
| languageDirection | Indicates the directionality of the element's text. The value will propagate to the element's children. |
| layout | The position and size of the VisualElement relative to its parent, as computed by the layout system. |
| localBound | Returns a Rect representing the Axis-aligned Bounding Box (AABB) after applying the transform, but before applying the layout translation. |
| name | The name of this VisualElement. |
| paddingRect | The rectangle of the padding area of the element, in the local space of the element. |
| panel | The panel onto which this VisualElement is attached. |
| parent | The parent of this VisualElement. |
| pickingMode | Determines if this element can be pick during mouseEvents or IPanel.Pick queries. |
| resolvedStyle | The final computed style values on a VisualElement (Read Only). |
| schedule | Retrieves this VisualElement's IVisualElementScheduler |
| style | Sets the style values on a VisualElement. |

| tooltip | Text to display inside an information box after the user hovers the element for a small amount of time. This is only supported in the Editor UI. |
| transform | Returns a transform object for this VisualElement. ITransform |
| usageHints | A combination of hint values that specify high-level intended usage patterns for the VisualElement. This property can only be set when the VisualElement is not yet part of a Panel. Once part of a Panel, this property becomes effectively read-only, and attempts to change it will throw an exception. The specification of proper UsageHints drives the system to make better decisions on how to process or accelerate certain operations based on the anticipated usage pattern. Note that those hints do not affect behavioral or visual results, but only affect the overall performance of the panel and the elements within. It's advised to always consider specifying the proper UsageHints, but keep in mind that some UsageHints might be internally ignored under certain conditions (e.g. due to hardware limitations on the target platform). |
| userData | This property can be used to associate application-specific user data with this VisualElement. |
| viewDataKey | Used for view data persistence (ie. tree expanded states, scroll position, zoom level). |
| visible | Indicates whether or not this element should be rendered. |
