class CMvcVisualPart: public _Base
A CMvcVisualPart is a type of visual component that keeps track of its container. Knowledge of its parent allows a visual part to perform invalidation and establish its own size based on the size of its container.Because of its extra member variables, a visual part is a slightly heavier object than the CMvcVisualComponent class. If you require many instantiations of a display object, you should probably derive each from CMvcVisualComponent and the container from CMvcVisualPart, CMvcLogicalPart or CMvcViewport.
