Is there a way to capture the direction that the mouse wheel is turning and how much it has turned?

Thanks,

I can capture if the mouse wheel is turning by doing this...

  
  
//Check for right clicks and middle wheel clicks  
  win->MouseDragStart(button,mx,my,MOUSEDRAGFLAGS_DONTHIDEMOUSE|MOUSEDRAGFLAGS_NOMOVE);  
  while (win->MouseDrag(&dx,&dy,&device)==MOUSEDRAGRESULT_CONTINUE)  
  {  
        
          GeSyncMessage(EVMSG_ASYNCEDITORMOVE);  
          BaseContainer bc = BaseContainer();  
            
          win->BfGetInputEvent(BFM_INPUT_MOUSE, &bc);  
          if (bc.GetLong(BFM_INPUT_CHANNEL) == BFM_INPUT_MOUSEWHEEL)  
          {  
              GePrint("MOUSE WHEEL SPINNING");  
          }  
  
  }

I am unsure how to determine which direction the mouse is spinning and how much it has spun. :)

Any help would be greatly appreciated.

Some code direct from the liquidtool.cpp example :wink:

  
bc=BaseContainer();  
win->BfGetInputEvent(BFM_INPUT_MOUSE,&bc);  
if (bc.GetLong(BFM_INPUT_CHANNEL)==BFM_INPUT_MOUSEWHEEL)  
{  
  rad+=bc.GetReal(BFM_INPUT_VALUE)/120.0;  
  rad=FCut(rad,RCO 0.1,RCO MAXRANGE);  
  GePrint(RealToString(rad));  
}

cheers,
