I'd like to know if there is any way of enabling drag&drop of an object (i.e. a sprite) only after holding down a mouse button for a certain amount of time.
What I want to accomplish is:
1) Enable the sprite's drag&drop behavior after holding down left button for 2 seconds.
2) Move the sprite and drop it at the desired position.
3) When dropped, disable drag&drop (this is easy)
