Mouse position on screen in flex

Question

I am trying to obtain the actual mouse co-ordinates on the screen so I can create a Native Window at that position but I dont seem to be able to find the right way to do this correctly.

I have tried various things, the closest thing I have at the moment is:

this.contentMouseX and this.contentMouseY

This gives me the coords on the current stage which is fine, then I add to that the:

NativeApplication.nativeApplication.activeWindow.x and activeWindow.y

Which is close, but this doesnt take into account the application title bar.

There must be an easier and more straightforward way of doing this I am sure, can anyone give advice cos I fail to find it on google?

I have tried localToGlobal which doesnt work, it seems that 'global' means within the application and not global to the screen which is of no use to me. Here is an example that shows the failure...

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <mx:Script>
        <![CDATA[
            import mx.core.Application;

            private function click(evt:MouseEvent):void
            {
                var pt:Point = new Point( this.contentMouseX, this.contentMouseY );
                var global:Point = Application.application.localToGlobal( pt );

                trace( "local_x: " + pt.x + " x " + pt.y );
                trace( "global_x: " + global.x + " x " + global.y );
            }
        ]]>
    </mx:Script>

    <mx:HBox horizontalAlign="center" width="100%">
        <mx:Button id="butt" label="Click" click="click(event)" />
    </mx:HBox>
</mx:WindowedApplication>

Solution

After a false start... Sorry about that...

You can use stage.nativeWindow.globalToScreen - this will do what you need.

In terms of position of the window (for completeness) - you can also look into stage.nativeWindow.x and stage.nativeWindow.y --- this will give you the position for the application on the desktop - from there - you can position relative to that point.

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import mx.core.Application;

private function click(evt:MouseEvent):void
{
  var pt:Point = new Point( this.butt.x, this.butt.y );
  var global:Point = Application.application.localToGlobal( pt );

  trace( "local_x: " + pt.x + " x " + pt.y );
  trace( "global_x: " + global.x + " x " + global.y );

  var p:Point = stage.nativeWindow.globalToScreen(new Point(this.butt.x, this.butt.y));

  trace(p.x + " x " + p.y);
  var na:NativeWindow = new NativeWindow(new NativeWindowInitOptions());
  na.visible = true;
  na.width = 100;
  na.height = 100;
  na.x = p.x;
  na.y = p.y;
  na.activate();

}
]]>
</mx:Script>


<mx:Button x="10" y="10" id="butt" label="Click" click="click(event)" />

</mx:WindowedApplication>

Nope, doesnt work. This is the problem I was getting, after localToGlobal it is the same value. 'global' is within the application, not related to the screen from what I have read and the experience I was getting using these functions

[Dan]

As Rick's comment, I have tried these functions and they dont work as I expected. They dont convert to screen co-ords at all.

[Dan]

Nope, evt.local is position of mouse within the button I clicked, stagex is position of mouse within the stage (same as the example in my post), I want the screen co-ords of the mouse.

Bummer, sorry I couldn't help - don't have a copy of FB3 to test on at work. Good luck.

gotta head to lunch - but when I get back - I'll check this again - thanks for the follow up and sorry if these guys didn't help. Now I'm interested - ha - let me get a little grub and I'll look into this. Fun.

[Mikosz]

Back - checking into this now.

[Dan]

Brilliant, thats all I needed was the "stage.nativeWindow.globalToScreen" function ... great thanks.

[Mikosz]

:D - no worries happy to help.
