| class MFormCustomDraw |
An abstract class which specifies the protocol for customising the way text and its background are drawn.
Common uses for this are to implement custom highlighting or to draw a background bitmap. You must create an object of a class derived from this class and call CTextLayout::SetCustomDraw(), passing a pointer to the object. All of these functions have default implementations. Your class can override any of the virtual functions listed below.
