Subject: ginput modifications --- How?

My problem is based on ginput which returns the (x,y) coordinates of a large cross-hair when the left-button mouse is clicked. The modified ginput would use a vertical line as a pointer (not a crosshair), and it would return the x-coordinate of the position of the vertical line when the left mouse-button is clicked. How can I modify ginput to accomplish this?
