Static Variables

defaultFocusIndexThe default focus index for newly created elements.

Variables

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.
capabilitiesThe GraphElement's capabilities.
elementTypeColorThe color used for the MiniMap view.
layerThe GraphElement's layer in the graph.
selectedTrue if the GraphElement is currently selected.
titleThe GraphElement'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

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

Public Functions

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.
GetGlobalCenterGet the GraphElement's center point.
GetPositionGet the GraphElement position.
HitTestSee if point is over the GraphElement.
IsAscendableChecks if the GraphElement is automatically brought to front when selected.
IsDroppableThe GraphElement is drag&droppable.
IsMovableThe GraphElement is movable.
IsResizableThe GraphElement is resizable.
IsSelectableThe GraphElement is selectable.
IsSelectedThe GraphElement is currently selected in specific container.
OnSelectedCalled when the GraphElement is selected.
OnUnselectedCalled when the GraphElement is unselected.

UnselectDeselect the GraphElement.
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
IndexOfRetrieves the child index of the specified VisualElement.
InsertInsert an element into this element's contentContainer
MarkDirtyRepaintTriggers a repaint of the VisualElement on the next frame.
OnPersistentDataReadyCalled when the persistent data is accessible and/or when the data or persistence key have changed (VisualElement is properly parented).

PlaceBehindPlaces 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.
PlaceInFrontPlaces 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.
RemoveRemoves this child from the hierarchy
RemoveAtRemove the child element located at this position from this element's contentContainer
RemoveFromHierarchyRemoves this element from its parent hierarchy
RemoveStyleSheetPathRemoves this stylesheet file from this element list of applied styles
