DigitizePoint

[Jim OLeary]

How do you access the Point object in DigitizePoint()? The documentations says that you pass it a function as a handler, and it passes a Point parameter to that function.

The first problem is that my taskpane does not know what a point is, so I made one:

function Point(x,y) {
        this.x = x;
        this.y = y;
        }

Next I made a Point object named "o":

var o = new Point(1,0)

Next I made a handler for DigitizePoint:

    function digitizePointHandler(o)
    {
        
    }

Next I called the DigitizePoint function from another function:

    function getDigitizePoint()
    {
        f = new digitizePointHandler(o)
        parent.ViewerFrame.mapFrame.DigitizePoint(f)
        alert("o.x is" + o.x)
    }

Hopefully DigitizePoint() takes that o parameter and fills it with the x and y points that the user's mouse has clicked. However, the final alert shows that o.x is still the same as it was in the beginning.

Any help would be appreciated.
