Sets the specified paint properties.

Parameters

PAINTGROUP nGroup

Indicates the paint properties to get and the structure pointed to by pProperty. Possible values are:

Value	Meaning
PAINT_GROUP_BRUSH	Set the Paintbrush properties. pProperty points to a PAINTBRUSH structure.
PAINT_GROUP_SHAPE	Set the Paint shape properties. pProperty points to a PAINTSHAPE structure.
PAINT_GROUP_REGION	Set the Paint region properties. pProperty points to a PAINTREGION structure.
PAINT_GROUP_FILL	Set the Paint fill properties. pProperty points to a PAINTFILL structure.
PAINT_GROUP_TEXT	Set the Paint fill properties. pProperty points to a PAINTTEXT structure.

const L_VOID * pProperty

Pointer to a PAINTXXX structure that contains the property values to set. The type of structure that this parameter points to is indicated by the nGroup parameter. The user should set the nSize and dwMask of any of the PAINTXXX structures with proper values before calling this function.
