These constants are used as return values by a control in response to an NM_CUSTOMDRAW notification code.

Constant/value Description
CDRF_DODEFAULT
0x00000000

CDRF_NEWFONT
0x00000002
 The application specified a new font for the item; the control will use the new font. For more information about changing fonts, see Changing fonts and colors. This occurs when the dwDrawStage of the NMCUSTOMDRAW structure equals CDDS_ITEMPREPAINT.
CDRF_SKIPDEFAULT
0x00000004
 The application drew the item manually. The control will not draw the item. This occurs when the dwDrawStage of the NMCUSTOMDRAW structure equals CDDS_ITEMPREPAINT.
