UCLASS (MinimalAPI)  
class UMultiButtonClickDragBehavior :  
    public UClickDragInputBehavior,  
    public IClickDragBehaviorTarget

Remarks

MultiButtonClickDragBehavior is an implementation of UClickDragInputBehavior that can manage several mouse buttons at once and also implements IClickDragBehaviorTarget directly, via a set of local lambda functions. To use/customize this class the client replaces the lambda functions with their own and enables/disables the buttons to capture.
