TSharedPtr< SDo... CursorDecoratorStackNode Decorator widget where we add temp doc tabs to
FVector2D DecoratorOffsetFromCursor Where the user grabbed the UI measured in screen space from its top-left corner
FOnInViewportUI... DropDelegate  
FVector2D LastContentSize What the size of the content was when it was last shown.
TSharedPtr< cla... UIBeingDragged What is actually being dragged in this operation

Constructors

Type Name Description
  FInViewportUIDragOperation ( const TSharedRef< class SWidget >&..., const FVector2D InDecoratorOffsetFr..., const FVector2D& OwnerAreaSize, FOnInViewportUIDropped& InDropDele... ) The constructor is protected, so that this class can only be instantiated as a shared pointer.

Destructors

Type Name Description
  ~FInViewportUIDragOperation ()  

Functions

Type Name Description
void BroadcastDropEvent ( const FVector2D InLocation )  
const FVecto... GetDecoratorOffsetFromCursor ()  
const FStrin... GetTypeId ()  
TSharedRef< ... New ( const TSharedRef< class SWidget >&..., const FVector2D InDecoratorOffset, const FVector2D& OwnerAreaSize, FOnInViewportUIDropped& InDropDele... ) Create this Drag and Drop Content
void OnDragged ( const FDragDropEvent& DragDropEven... ) Called when the mouse was moved during a drag and drop operation

Overridden from FDragDropOperation
