DrawIconEx info  Overview  Group

The DrawIconEx function draws an icon or cursor in the client area of the window of the specified device context, performing the specified raster operations, and stretching or compressing the icon or cursor as specified.

BOOL DrawIconEx(

    HDC hdc,

// handle to device context

    int xLeft,

// x-coordinate of upper left corner

    int yTop,

// y-coordinate of upper left corner

    HICON hIcon,

// handle to icon to draw

    int cxWidth,

// width of the icon

    int cyWidth,

// height of the icon

    UINT istepIfAniCur,

// index of frame in animated cursor

    HBRUSH hbrFlickerFreeDraw,

// handle to background brush

    UINT diFlags

// icon-drawing flags

   );

Parameters

hdc
Identifies the device context for a window.
xLeft
Specifies the logical x-coordinate of the upper-left corner of the icon or cursor.
yTop
Specifies the logical y-coordinate of the upper-left corner of the icon or cursor.
hIcon
Identifies the icon or cursor to be drawn. This parameter can identify an animated cursor. The icon or cursor resource must have been previously loaded by using the LoadImage function.
cxWidth
Specifies the logical width of the icon or cursor. If this parameter is zero and the diFlags parameter is DI_DEFAULTSIZE, the function uses the SM_CXICON or SM_CXCURSOR system metric value to set the width. If this parameter is zero and DI_DEFAULTSIZE is not used, the function uses the actual resource width.
cyWidth
Specifies the logical height of the icon or cursor. If this parameter is zero and the diFlags parameter is DI_DEFAULTSIZE, the function uses the SM_CYICON or SM_CYCURSOR system metric value to set the width. If this parameter is zero and DI_DEFAULTSIZE is not used, the function uses the actual resource height.
istepIfAniCur
Specifies the index of the frame to draw, if hIcon identifies an animated cursor. This parameter is ignored if hIcon does not identify an animated cursor.
hbrFlickerFreeDraw
Identifies a brush that the system uses for flicker-free drawing. If hbrBkgnd is a valid brush handle, the system creates an offscreen bitmap using the specified brush for the background color, draws the icon or cursor into the bitmap, and then copies the bitmap into the device context identified by hdc. If hbrBkgnd is NULL, the system draws the icon or cursor directly into the device context.
diFlags
Specifies the drawing flags. This parameter can be one of the following values:

Value

Meaning

DI_COMPAT

Draws the icon or cursor using the system default image rather than the user-specified image.

DI_DEFAULTSIZE

Draws the icon or cursor using the width and height specified by the system metric values for cursors or icons, if the cxWidth and cyWidth parameters are set to zero. If this flag is not specified and cxWidth and cyWidth are set to zero, the function uses the actual resource size.

DI_IMAGE

Draws the icon or cursor using the image.

DI_MASK

Draws the icon or cursor using the mask.

DI_NORMAL

Combination of DI_IMAGE and DI_MASK.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The DrawIconEx function places the iconís upper-left corner at the location specified by the xLeft and yTop parameters. The location is subject to the current mapping mode of the device context.
