Double Click on Graphic in Map is not Working

Hi,
I had created an application where the user can click on map and a marker will be created and it stores x y values and stored in database and user can also drag the marker and place it to appropriate position and after the user drag and drop the marker we have a confirm button to send the x y values to database. I need to remove that confirm button and replace that with the double click where user double clicks the marker parameters should pass.

For dragging marker i use mousedown event, but when i add doubleclick event its not working

gr.doubleClickEnabled = true;
gr.addEventListener(MouseEvent.DOUBLE_CLICK,registerComplaint);
gr.addEventListener(MouseEvent.MOUSE_DOWN,mousedownGraphic);

even when i comment the mouse down event double click on graphic marker is not working.

Help me out in this task as i need to do urgently.

Regards
Arun Mohan

Hi,

For  MouseEvent.MOUSE_DOWN the trace() method is working ,for DOUBLE_CLICK event there is no action.

While I can't possibly guess the cause your problem, there is an easy workaround for this.

...
// record the time for the last mouse down
private var _lastMouseDownTime:uint = new Date().time;
// how fast the second mouse down needs to be to qualify for double click
private var _doubleClickThreshold:uint = 500;
...
// traces mouse down and double click
private function mouseDown(e:MouseEvent):void {
            trace("mousedown");
            var mouseDownTime:uint = new Date().time;
            if(mouseDownTime - _lastMouseDownTime <= _doubleClickThreshold){
                trace("doubleclick");
            }
            _lastMouseDownTime = mouseDownTime;
}

I cannot tell why it's not working for you from the info you provided, but you certainly can listen to both MouseEvent.MOUSE_DOWN and MouseEvent.DOUBLE_CLICK to get both events registered. Can you trace() on MouseEvent.DOUBLE_CLICK?

But you get trace() on MouseEvent.MOUSE_DOWN, right? Can you comment your code out so that both functions for MOUSE_DOWN and DOUBLE_CLICK have only trace() in them and test?
