class in UnityEngine.UIElements
/
Inherits from:UIElements.VisualElement
/
Implemented in:UnityEngine.UIElementsModule
Creates a tab to organize content on different screens.
A Tab has a header that can respond to pointer and mouse events. The header can hold an icon, a label, or both.
The Tab content container can hold anything inside of it giving more flexibility to customize its layout.
For more information, refer to UXML element Tab.

| contentRect | The rectangle of the content area of the element, in the local space of the element. (Read Only) |
| customStyle | The custom style properties accessor of a VisualElement (Read Only). |
| dataSource | Assigns a data source to this VisualElement which overrides any inherited data source. This data source is inherited by all children. |
| dataSourcePath | Path from the data source to the value. |
| dataSourceType | The possible type of data source assignable to this VisualElement. This information is only used by the UI Builder as a hint to provide some completion to the data source path field when the effective data source cannot be specified at design time. |
| disablePlayModeTint | Play-mode tint is applied by default unless this is set to true. It's applied hierarchically to this VisualElement and to all its children that exist on an editor panel. |
| enabledInHierarchy | Returns true if the VisualElement is enabled in its own hierarchy. |

| layout | The position and size of the VisualElement relative to its parent, as computed by the layout system. (Read Only) |
| 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 rendered style values of a visual element, as it's rendered in the current frame.(Read Only) |
| scaledPixelsPerPoint | Return the resulting scaling from the panel that considers the screen DPI and the customizable scaling factor, but not the transform scale of the element and its ancestors. See Panel.scaledPixelsPerPoint. This should only be called on elements that are part of a panel. |
| schedule | Retrieves this VisualElement's IVisualElementScheduler |
| style | Sets the style values on a VisualElement. |
| styleSheets | Returns a VisualElementStyleSheetSet that manipulates style sheets attached to this element. |
| this[int] | Retrieves the child element at a specific index. |
| 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, such as tree expanded states, scroll position, or zoom level. |
| visible | Indicates whether or not this element should be rendered. |
| visualTreeAssetSource | Stores the asset reference, if the generated element is cloned from a VisualTreeAsset. |
| worldBound | Returns a Rect representing the Axis-aligned Bounding Box (AABB) after applying the world transform. |
| worldTransform | Returns a matrix that cumulates the following operations (in order): -Local Scaling -Local Rotation -Local Translation -Layout Translation -Parent worldTransform (recursive definition - consider identity when there is no parent) |
| HasBubbleUpHandlers | Return true if event handlers for the event propagation BubbleUp phase have been attached to this object. |
| HasTrickleDownHandlers | Returns true if event handlers, for the event propagation TrickleDown phase, are attached to this object. |
| RegisterCallback | Adds an event handler to the instance. If the event handler has already been registered for the same phase (either TrickleDown or BubbleUp) then this method has no effect. |
| RegisterCallbackOnce | Adds an event handler to the instance. If the event handler has already been registered for the same phase (either TrickleDown or BubbleUp) then this method has no effect. The event handler is automatically unregistered after it has been invoked exactly once. |
| UnregisterCallback | Remove callback from the instance. |
| Blur | Tell the element to release the focus. |
| Focus | Attempt to give the focus to this element. |
| Add | Add an element to this element's contentContainer |
| AddToClassList | Adds a class to the class list of the element in order to assign styles from USS. Note the class name is case-sensitive. |

| MarkDirtyRepaint | Triggers a repaint of the VisualElement on the next frame. This method is called internally when a change occurs that requires a repaint, such as when UIElements.BaseField_1.value is changed or the text in a Label. If you are implementing a custom control, you can call this method to trigger a repaint when a change occurs that requires a repaint such as when using generateVisualContent to render a mesh and the mesh data has now changed. |
| PlaceBehind | Places this element right before the sibling element in their parent children list. If the element and the sibling position overlap, the element will be visually behind of its sibling. |
