I am trying to know how much the mouse moves when clicking down on a certain widget, but I can't figure out how. I noticed only a mouse wheel delta property and nothing for the mouse pointer x,y deltas since the click. I am looking to do something such as

if(e.lbutton().isDown() && !e.rbutton().isDown()) {
    pitch -= e.dy();
}

I am currently handling it like this:

>current = e.pos();
>xdelta = current.x - previous.x;
>ydelta = current.y - previous.y;
>previous = current;
I'm just wondering if there is a built in solution that I missed.

There is only information about coordinates where mouse button down event occured.

event.lbutton.downX, event.lbutton.downY - stores coordinates of button down event.
