The FillRect function fills a rectangle by using the specified brush. This function includes the left and top borders, but excludes the right and bottom borders of the rectangle.
int FillRect(
| HDC hDC, | // handle to device context |
| CONST RECT *lprc, | // pointer to structure with rectangle |
| HBRUSH hbr | // handle to brush |
| ); |
Parameters
hDC
Identifies the device context.
lprc
Points to a RECT structure that contains the logical coordinates of the rectangle to be filled.
hbr
Identifies the brush used to fill the rectangle.
Return Values
If the function succeeds, the return value is TRUE.
If the function fails, the return value is FALSE. To get extended error information, call GetLastError.
Remarks
The brush identified by the hbr parameter may be either a handle to a logical brush or a color value. If specifying a handle to a logical brush, call one of the following functions to obtain the handle: CreateHatchBrush, CreatePatternBrush, or CreateSolidBrush. Additionally, you may retrieve a handle to one of the stock brushes by using the GetStockObject function. If specifying a color value for the hbr parameter, it must be one of the standard system colors (the value 1 must be added to the chosen color). For example:
FillRect(hdc, &rect, (HBRUSH) (COLOR_ENDCOLORS+1));
For a list of all the standard system colors, see GetSysColor.
When filling the specified rectangle, FillRect does not include the rectangle's right and bottom sides. GDI fills a rectangle up to, but not including, the right column and bottom row, regardless of the current mapping mode.
