This method sets the shape of the pointer, the hot spot of the pointer, and the colors to use for the cursor if the cursor is multicolored. The GDI calls GPE::MovePointerseparately to move or hide the cursor.

Parameters

pMask
[IN] Pointer to a mask containing the cursor shape.
pColorSurf
[IN] Pointer to a surface specifying the colors to use for the cursor.
xHot
Horizontal location of the cursor's hot spot.
yHot
Vertical location of the cursor's hot spot.
cx
Width of the cursor.
cy
Height of the cursor.

Remarks

The pMaskparameter points to a 1-bpp surface with a width of cxand a height of (2 cy). The top half defines the ANDmask for the pointer, and the lower half defines the XORmask. Taken together, these masks provide 2 bits of information for each pixel of the pointer image. The following truth table shows display results for different values in the ANDand XORmasks.

AND mask value XOR mask value Result displayed on screen
0 0 Black.
0 1 White.
1 0 Transparent; pixel is unchanged.
1 1 Inverts the pixel color.

These masks provide for a black-and-white image and enable transparency and inversion of pointer pixels.

If pColorSurfis not NULL, use the colors for the corresponding pixels of the color surface instead of the XORmask value for pixels where the ANDmask value is 0.
