Re: WindowApplication.as edit / ApplicationDPI scaling bug ?

This code works for me (by scaling a group). I leave it you to determine a suitable calculation for newScale value. Custom runtimeDPIprovider not needed as default returns 160 (which is fine) 

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009";
xmlns:s="library://ns.adobe.com/flex/spark"
                       xmlns:mx="library://ns.adobe.com/flex/mx"
                       applicationDPI="160"
                       creationComplete="init()">

    <fx:Script>
        <![CDATA[
            import mx.events.FlexEvent;

            protected function init():void
            {
                var newScale:Number = 2;
                grp.scaleX = newScale;
                grp.scaleY = newScale;
            }
        ]]>
    </fx:Script>

    <s:Group id="grp"
             left="0" right="0" top="0" bottom="0">
<s:Label id="LeftMarker" left="0" verticalCenter="0" text="&lt;--- LEFT" fontSize="24"/>
<s:Label id="MiddleMarker" horizontalCenter="0" verticalCenter="0" text="&gt; &gt; &gt; MIDDLE &lt; &lt; &lt;" fontSize="24"/>
<s:Label id="RightMarker" right="0" verticalCenter="0" text="RIGHT ---&gt;" fontSize="24"/> 

    </s:Group>

</s:WindowedApplication>

I havent tested it but a possible workaround would be to avoid flex scaling completely and write your own... either set stage.scaleX/Y as appropriate (or maybe you will need to put all your content inside a group and scale the group).
Having said that, the more i think about it, i'm not sure scaling a desktop app is ideal (even if window cant be resized by user) - but i'm guessing your app is too far into development to change that?

Hi All,
I submitted a bug to the Jira system around how the application scaling using applicationDPI for desktop Air Apps seems to be broken. I've included screenshots, example code etc.. so I won't go into detail here, if you're interested and can help please do have a look. https://issues.apache.org/jira/browse/FLEX-34653
Anyway, I've checked out the source... and have been playing around but I can't seem to get any changes to the WindowedApplication.as (\frameworks\projects\airspark\src\spark\components) to do anything. Trace statements don't work, I've even put in deliberate errors... to no effect. Changes and trace statements in other parts of the framework such as systemManager.as appear so I know I'm compiling and using my edited source.
Is there something special about the WindowedApplication.as ... is it overridden somewhere in the build? 

Any help appreciated.

Jason :)
