FillRect
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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
