Hello fellow programmers,

Obviously, I have a question.  :)

What I want to do is change the mouse cursor, not to a hand or anything, I
can do that, but rather to various LARGER objects than the standard
mouse pointer allows.  The easiest way to explain this would be your
standard joe-paint program...when you click on various icons, the mouse
cursor changes to say, a pencil, or some other paint-oriented object that
is larger than the standard 16x16 pixels.

I've been using int33, function 9 to change the cursor, but as you know,
that's limited to 16x16.

Is there some way to create larger cursors, or will I have to turn off
the regular mouse cursor and manually move a sprite by reading the mouse's
x-y coordinates and drawing/erasing it at that position?  (sprite
being my terminology for a small bitmapped image...from the C-64 days!)
I haven't tried doing that, but it's gotta be SLOW...

I'm programming in Borland C++ v3.0 using a 386-25, using the standard
VGA modes, running and programming for DOS, and using as a reference,
"Microsoft Mouse Programmer's Reference"

Any suggestions/ideas would be appreciated.  :)

Using a sprite is the only way I know in standard VGA modes.  XGA does support
larger mouse cursors, though.
