Syntax
UCLASS&40;&41;
class URectangleMarqueeInteraction :
public UObject,
public IClickDragBehaviorTarget
Remarks
URectangleMarqueeInteraction is a simplified version of URectangleMarqueeMechanic that is not a UInteractionMechanic, which requires a base Tool/ToolManager. This variant does not create it's own InputBehavior, but is still a ClickDragBehaviorTarget.
DrawHUD() must be called by the owning code.
