CDrawingManager::GrayRect
Fills a rectangle with a specified gray color.
BOOL GrayRect(
CRect rect,
int nPercentage = -1,
COLORREF clrTransparent = (COLORREF)-1,
COLORREF clrDisabled = (COLORREF)-1
);
Parameters
[in] rect
The rectangular area to fill.[in] nPercentage
The percentage of gray you want in the rectangle.[in] clrTransparent
The transparent color.[in] clrDisabled
The color that this method uses for de-saturation if nPercentage is set to -1.
Return Value
TRUE if the method was successful; otherwise FALSE.
Remarks
For the parameter nPercentage, a lower value indicates a darker color.
The maximum value for nPercentage is 200. A value larger than 200 does not change the appearance of the rectangle. If the value is -1, this method uses clrDisabled to limit the saturation of the rectangle.
