virtual void OnDraw(
CDC* pDC,
const CRect& rcBounds,
const CRect& rcInvalid
);
Параметры
pDC
The device context in which the drawing occurs.rcBounds
The rectangular area of the control, including the border.rcInvalid
The rectangular area of the control that is invalid.
Заметки
OnDraw is typically called for screen display, passing a screen device context as pDC. The rcBounds parameter identifies the rectangle in the target device context (relative to its current mapping mode). The rcInvalid parameter is the actual rectangle that is invalid. In some cases this will be a smaller area than rcBounds.
