backgroundColor with showFlexChrome=”false”
February 5th, 2009
I came across a scenario that I wanted an AIR app to have a background color set while systemChrome="true" but showFlexChrome="false". Here is another post describing the problem. I tried to figure out what was going on and how the green-greyish background shows up (or white background in Flex 4) but couldn't figure out where that is created. But I did notice that when showFlexChrome="false" that the backgroundAlpha style was set to 0. So the workaround for the problem is to set the backgroundAlpha back to 1 after the application has created it self (on creationComplete event).
-
<?xml version="1.0" encoding="utf-8"?>
-
<mx:WindowedApplication
-
xmlns:mx="http://www.adobe.com/2006/mxml"
-
layout="vertical"
-
backgroundColor="0x0000FF"
-
creationComplete="setBG()"
-
showFlexChrome="false"

<mx:Script>

<![CDATA[
-
private function setBG():void
-
{
-
this.setStyle("backgroundAlpha", 1);
-
}

]]>
-
</mx:Script>
-
</mx:WindowedApplication>
Is there an easy way to do this? So the easier way of setting a background color withe showFlexChrome="false" is to set the background color of the SWF.
