Hide Mouse Pointer in Display Driver

NTDEV
1

Hi,

Is it possible to hide the mouse pointer in the display driver so that
the mouse cursor doesn’t get drawn? I am thinking if there could be a
way to set some flags or something so that the call to draw the mouse
surface doesn’t get called or if it could be handled in copybits to
detect it’s a mouse surface and ignore it.

If you implement DrvSetPointerShape and DrvMovePointer, then GDI will
call your driver handle all of the cursor drawing. You can do what you
like.

Tim,

Would this apply to mirror driver as well?

To be honest, I don’t know, but it’s certainly a very easy experiment to
try.
