Actually I don't intend to.
Maybe another example will help.
Suppose I need to draw a line between 2 "linked" elements. The usual way is:
1. move your mouse over first element (OnHover is animated denoting possible selection),
2. press mouse down and hold (OnDragStart for example)
3. move your mouse over second element holding the mouse down (would like to know where am I now, what element is under the mouse to animate it like in point 1)
4. you release your mouse over second element to finish the link. (event?)
Advices what event I could use are much appreciated.
