Detailed Description

template<typename ManagerT, typename AssistantT>
class MANAGED_DRAW_BEHAVIOR< ManagerT, AssistantT >

Template base for SHAPE_DRAW_BEHAVIOR implementations that wrap a MULTISTEP_GEOM_MANAGER and an assistant.

Provides the standard pass-through methods (IsStarted, AddPoint, etc.) so that concrete classes only need to supply ApplyToShape() and any shape-specific geometry accessors.

Template Parameters

ManagerT	the geometry-manager type (e.g. ARC_GEOM_MANAGER).
AssistantT	the visual-assistant type (e.g. ARC_ASSISTANT).
