class in UnityEngine.UIElements
/
Inherits from:UIElements.VisualElement
/
Implemented in:UnityEngine.UIElementsModule
A vertically scrollable area that only creates visual elements for visible items while allowing the binding of many more items. As the user scrolls, visual elements are recycled and re-bound to new data items.
| itemSelectedVariantUssClassName | USS class name of item elements in elements of this type, when they are selected. |
| itemUssClassName | USS class name of item elements in elements of this type. |
| ussClassName | USS class name of elements of this type. |
| bindItem | Callback for binding a data item to the visual element. |
| itemHeight | ListView requires all visual elements to have the same height so that it can calculate a sensible scroller size. This property must be set for the list view to function. |
| itemsSource | The items data source. This property must be set for the list view to function. |
| makeItem | Callback for constructing the VisualElement that will serve as the template for each recycled and re-bound element in the list. This property must be set for the list view to function. |
| selectedIndex | Currently selected item index in the items source. If multiple items are selected, this will return the first selected item's index. |
| selectedItem | The currently selected item from the items source. If multiple items are selected, this will return the first selected item. |
| selectionType | Controls the selection state, whether: selections are disabled, there is only one selectable item, or if there are multiple selectable items. |
| Refresh | Clear, recreate all visible visual elements, and rebind all items. This should be called whenever the items source changes. |
| ScrollTo | Scroll to a specific visual element. |
| ScrollToItem | Scroll so that a specific item index from the items source is visible. |
| onItemChosen | Callback for when an item is chosen (double-click). This is different from just a selection. |
| onSelectionChanged | Callback for a selection change. |
| canGrabFocus | Return true if the element can be focused. |
| delegatesFocus | Whether the element should delegate the focus to its children. |
| focusable | True if the element can be focused. |
| focusController | Return the focus controller for this element. |
| 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 this element, usually this |
| customStyle | Returns the custom style properties accessor for this element. |
| enabledInHierarchy | Returns true if the VisualElement is enabled in its own hierarchy. |
| enabledSelf | Returns true if the VisualElement is enabled locally. |
| hierarchy | Access to this element physical hierarchy |
| pickingMode | Determines if this element can be pick during mouseEvents or IPanel.Pick queries. |
| resolvedStyle | Returns the VisualElement resolved style values. |
| schedule | Retrieves this VisualElement's IVisualElementScheduler |
| style | Reference to the style object of this element. |
| styleSheets | Returns a VisualElementStyleSheetSet that manipulates style sheets attached to this element. |
| this[int] | Access to this element physical hierarchy |
| tooltip | Text to display inside an information box after the user hovers the element for a small amount of time. |
| 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). |
| HandleEvent | Handle an event, most often by executing the callbacks associated with the event. |
| HasBubbleUpHandlers | Return true if event handlers for the event propagation BubbleUp phase have been attached on 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. |
| SendEvent | Sends an event to the event handler. |
| 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 |
| BringToFront | Brings this element to the end of its parent children list. The element will be visually in front of any overlapping sibling elements. |
| Children | Returns the elements from its contentContainer |
| Clear | Remove all child elements from this element's contentContainer |
| Contains | Returns true if the element is a direct child of this VisualElement |
| ElementAt | Retrieves the child element at position |
| EnableInClassList | Enables or disables the class with the given name. |
| FindAncestorUserData | Searchs up the hierachy of this VisualElement and retrieves stored userData, if any is found. |
| FindCommonAncestor | Finds the lowest commont ancestor between two VisualElements inside the VisualTree hierarchy |
| GetFirstAncestorOfType | Walks up the hierarchy, starting from this element's parent, and returns the first VisualElement of this type |
| GetFirstOfType | Walks up the hierarchy, starting from this element, and returns the first VisualElement of this type |
| IndexOf | Retrieves the child index of the specified VisualElement. |
| Insert | Insert an element into this element's contentContainer |
| MarkDirtyRepaint | Triggers a repaint of the VisualElement on the next frame. |
| 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. |
| PlaceInFront | Places this element right after the sibling element in their parent children list. If the element and the sibling position overlap, the element will be visually in front of its sibling. |
| Remove | Removes this child from the hierarchy |
| RemoveAt | Remove the child element located at this position from this element's contentContainer |
| RemoveFromHierarchy | Removes this element from its parent hierarchy |
| SendEvent | Sends an event to the event handler. |
| SendToBack | Sends this element to the beginning of its parent children list. The element will be visually behind any overlapping sibling elements. |
| SetEnabled | Changes the VisualElement enabled state. A disabled VisualElement does not receive most events. |
| Sort | Reorders child elements from this VisualElement contentContainer. |
| ToggleInClassList | Toggles between adding and removing the given class name from the class list. |
