Parameters: DevID
Index
Color
Return Value: ERR_OK
ERR_FAILED- returned if Index if other than 0 or 1
int seSetCursorPixel(int DevID, long x, long y, DWORD Color)
Description: Draws a single pixel into the hardware cursor. The pixel will be of color 'Color'
located at (x,y) pixels relative to the top left of the hardware cursor.
The value of 'Color' must be 0 to 3. Values 0 and 1 refer to the two user definable
colors. If 'Color' is 2 then the pixel will be transparent and if the value is 3 the pixel
will be an inversion of the underlying screen color.
Parameters: DevID
(x, y)
Color
Return Value: ERR_OK
int seDrawCursorLine(int DevID, long x1, long y1, long x2, long y2, DWORD Color)
Description: Draws a line between the two endpoints, (x1,y1) and (x2,y2), in the hardware cursor
display buffer using color 'Color'.
The value of 'Color' must be 0 to 3. Values 0 and 1 refer to the two user definable
colors. If 'Color' is 2 then the pixel will be transparent and if the value is 3 the pixel
will be an inversion of the underlying screen color.
Parameters: DevID
(x1,y1)
(x2,y2)
Color
Return Value: ERR_OK
int seDrawCursorRect(int DevID, long x1, long y1, long x2, long y2, DWORD Color,
BOOL SolidFill)
Description: This routine will draw a rectangle in hardware cursor memory. The upper left corner
of the rectangle is defined by the point (x1,y1) and the lower right is the point
(x2,y2). Both points are relative to the upper left corner of the cursor.
The value of 'Color' must be 0 to 3. Values 0 and 1 refer to the two user definable
colors. If 'Color' is 2 then the pixel will be transparent and if the value is 3 the pixel
result will be an inversion of the underlying screen color.
If 'SolidFill' is specified the interior of the rectangle will be filled with 'Color',
otherwise the rectangle is only outlined in 'Color'.
