Get cursor coordinates over tested object?

Thanks for the assistance everyone, I was able to get what I needed. Here's the script I wrote to get the current X & Y coordinates and double click the object at that point.

var screenMouseX, screenMouseY, controlPoint, onscreenObj;

function double_click()
{

//Gets current mouse cursor coordinates on screen
screenMouseX = Sys.Desktop.MouseX;
screenMouseY = Sys.Desktop.MouseY;

Log.Message("X: " + screenMouseX + " Y: " + screenMouseY);

//gets the object below the mouse cursor
onscreenObj = Sys.ObjectFromPoint(screenMouseX,screenMouseY); 

//converts the screen coordinates to coordinates relative to the object
controlPoint = onscreenObj.ScreenToWindow(screenMouseX,screenMouseY);

Log.Message("objX: " + controlPoint.X + " objY: " + controlPoint.Y);

//double clicks the object from the converted coordinates
onscreenObj.DblClick(controlPoint.X,controlPoint.Y);

}
