Creates a monochrome cursor having the specified size, bit patterns, and hot spot.
To create a colored cursor at run time you can use the CreateIconIndirect function, which creates a cursor based on the content of an ICONINFO structure.
Syntax
HCURSOR CreateCursor(
[in, optional] HINSTANCE hInst,
[in] int xHotSpot,
[in] int yHotSpot,
[in] int nWidth,
[in] int nHeight,
[in] const VOID *pvANDPlane,
[in] const VOID *pvXORPlane
);
Parameters
[in, optional] hInst
Type: HINSTANCE
A handle to the current instance of the application creating the cursor.
[in] xHotSpot
Type: int
The horizontal position of the cursor's hot spot.
[in] yHotSpot
Type: int
The vertical position of the cursor's hot spot.
[in] nWidth
Type: int
The width of the cursor, in pixels.
[in] nHeight
Type: int
The height of the cursor, in pixels.
[in] pvANDPlane
Type: const VOID*
An array of bytes that contains the bit values for the AND mask of the cursor, as in a monochrome bitmap. See remarks.
[in] pvXORPlane
Type: const VOID*
An array of bytes that contains the bit values for the XOR mask of the cursor, as in a monochrome bitmap. See remarks.
Return value
Type: HCURSOR
If the function succeeds, the return value is a handle to the cursor.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
Remarks
To determine the nominal size of a cursor, use the GetSystemMetrics function, specifying the SM_CXCURSOR or SM_CYCURSOR value. Also, you can use the DPI-aware version of this API, see GetSystemMetricsForDpi. For more information see High DPI Desktop Application Development on Windows.
For more information about pvANDPlane and pvXORPlane parameters see description of lpBits parameter of CreateBitmap function.
CreateCursor applies the following truth table to the AND and XOR bitmasks:
| AND bitmask | XOR bitmask | Display |
|---|---|---|
| 0 | 0 | Black |
| 0 | 1 | White |
| 1 | 0 | Screen |
| 1 | 1 | Reverse screen |
Before closing, an application must call the DestroyCursor function to free any system resources associated with the cursor.
DPI Virtualization
This API does not participate in DPI virtualization. The output returned is in terms of physical coordinates, and is not affected by the DPI of the calling thread. Note that the cursor created may still be scaled to match the DPI of any given window it is drawn into.Examples
For an example, see Creating a Cursor.
