TARGET - VirtualOutput definitions?

[krel]

I'm trying to use a button press to send a small amount of scrollwheel change, as follows:

 

int scrollup() { VirtualOutput(OUT_TYPE_MOUSE, OUT_ID_AXIS+2, 5); }

 

int scrolldn() { VirtualOutput(OUT_TYPE_MOUSE, OUT_ID_AXIS+2, -5); }

 

MapKey(&W1, H2U, EXEC("scrollup();"));

MapKey(&W1, H2D, EXEC("scrolldn();"));

 

This works well, except that every time I click the button, it moves the mouse to the center of my screen. I suspect it's a problem with the definitions, but I can't find where those are set, where OUT_ID_AXIS is defined. Any suggestions?

To answer my own question (in case anyone finds this particular question via google some day in the future) I had to make a copy of target.tmh and change

 

if(cfg & CREATE_MOUSE) PlugMouse(1);

 

to

 

if(cfg & CREATE_MOUSE) PlugMouse(0);

 

which if I understand it correctly, is absolute vs relative positioning.
