Determining if a mouse is currenty over a certain object


I’m trying to solve what seems to be pretty basic task. However, I was unable to find a solution.
Could you please tell me how can I determine if the mouse is already over a certain object? The this.addEventListener(MouseEvent.MOUSE_OVER, onOver); doesn’t work because it will fire only what the mouse moves over from not being over. I’m trying to be able to tell if the mouse is over even without moving mouse, something like “this.isMouseOver()”.

Is it possible with some generic command without comparing the coordinates of the mouse and the object?
