Static Properties

defaultFocusIndexThe default focus index for newly created elements.


canGrabFocusReturn true if the element can be focused.
focusControllerReturn the focus controller for this element.
focusIndexAn integer used to sort focusables in the focus ring. A negative value means that the element can not be focused.
capabilitiesGraph element's capabilities.
elementTypeColorColor used for the MiniMap view.
layerElement's layer in the graph.
selectedTrue if element is currently selected.
titleThe element's title.
childCount Number of child elements in this object's contentContainer
clippingOptionsShould this element clip painting to its boundaries.
contentContainer child elements are added to this element, usually this
dataWatchAccess to this element data watch interface.
enabledInHierarchyReturns true if the VisualElement is enabled in its own hierarchy.
enabledSelfReturns true if the VisualElement is enabled locally.
persistenceKeyUsed for view data persistence (ie. tree expanded states, scroll position, zoom level).
scheduleRetrieves this VisualElement's IVisualElementScheduler
shadow Access to this element physical hierarchy

userDataThis property can be used to associate application-specific user data with this VisualElement.

Public Methods

HandleEventHandle an event, most often by executing the callbacks associated with the event.
HasBubbleUpHandlersReturn true if event handlers for the event propagation BubbleUp phase have been attached on this object.
HasTrickleDownHandlersReturns true if event handlers, for the event propagation TrickleDown phase, are attached to this object.
RegisterCallbackAdds 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.
SendEventSends an event to the event handler.
UnregisterCallbackRemove callback from the instance.
BlurTell the element to release the focus.
FocusAttempt to give the focus to this element.
GetPositionGet element position.
HitTestSee if point is over element.
IsAscendableChecks if the Element is automatically brought to front when selected.
IsDroppableElement is drag&droppable.
IsMovableElement is movable.
IsResizableElement is resizable.
IsSelectableElement is selectable.
IsSelectedElement is currently selected in specific container.
OnSelectedCalled when element is selected.
OnUnselectedCalled when element is unselected.
ResetLayerReset the element to its original layer.
SelectSelect element.
SetPositionSet element position.
UnselectDeselect element.
AddAdd an element to this element's contentContainer
AddStyleSheetPathAdds this stylesheet file to this element list of applied styles
BringToFrontBrings this element to the end of its parent children list. The element will be visually in front of any overlapping sibling elements.
ChildrenReturns the elements from its contentContainer
ClearRemove all child elements from this element's contentContainer
ContainsReturns true if the element is a direct child of this VisualElement
ElementAtRetrieves the child element at position
EnableInClassListEnables or disables the class with the given name.
FindAncestorUserDataSearchs up the hierachy of this VisualElement and retrieves stored userData, if any is found.
FindCommonAncestorFinds the lowest commont ancestor between two VisualElements inside the VisualTree hierarchy
GetEnumeratorAllows to iterate into this elements children
GetFirstAncestorOfTypeWalks up the hierarchy, starting from this element's parent, and returns the first VisualElement of this type
GetFirstOfTypeWalks up the hierarchy, starting from this element, and returns the first VisualElement of this type
GetFullHierarchicalPersistenceKeyCombine this VisualElement's VisualElement.persistenceKey with those of its parents to create a more unique key for use with VisualElement.GetOrCreatePersistentData.
GetOrCreatePersistentDataTakes a reference to an existing persisted object and a key and returns the object either filled with the persisted state or as-is.
HasStyleSheetPathChecks if this stylesheet file is in this element list of applied styles
