DrvMovePointer moves the pointer to a new position and ensures that GDI
does not interfere with the display of the pointer.
Parameters
-
pso
-
Points to a SURFOBJ structure that describes the
surface of a display device.
-
x,y
-
Specify the x and y coordinates on the display where the hot
spot of the pointer should be positioned. An x value of -1 indicates that the pointer should be removed from
the display because drawing is about to occur where it is presently located.
If the pointer has been removed from the display and the x value is
nonnegative, the pointer should be restored.
-
prcl
-
Points to a RECTL structure defining an area that bounds all pixels affected
by the pointer on the display. GDI will not draw in this rectangle without
first removing the pointer from the screen. This parameter can be null.
Comments
DrvMovePointer will not be called while any thread is drawing in the
display driver unless the GCAPS_ASYNCMOVE flag is set in the flGraphicsCaps
member of the DEVINFO structure.
DrvMovePointer is required for display drivers only if DrvSetPointerShape
is also supported.
If a driver has registered the specified pointer using DrvSetPointerShape,
DrvMovePointer must not fail.
