Re: [flexcoders] Unable to Dynamically Changing BG image

Title: Re: [flexcoders] Unable to Dynamically Changing BG image





Okay, I confess, in the Flex Style Explorer I faked the dynamic application background switching.   It’s really the following (this is simplified, but should explain the point):

<mx:Application marginLeft=”0” marginTop=”0” marginRight=”0” marginBottom=”0”> 
    <mx:VBox width=”100%” height=”100%” id=”myBackground”>

    <mx:VBox>
</mx:Application>

With setStyle calls pointing to the VBox, not the application.  (e.g. myBackground.setStyle(‘backgroundColor’, 0xFF0000); )

Sorry for being so sneaky.

I've spent a lot of time researching this issue within flexcoders,
Google, and iteration::two book and still no luck.

I'm basically trying to replicate what the Flex Style Explorer
(http://weblogs.macromedia.com/mc/archives/FlexStyleExplorer.html)
does where a user can choose their own background and styles. 

I cannot get this to work for the life of me. I've read everywhere
that once you declare a theme, that's it. You can't dynamically swap
in a new one. In my code below, I'm basically trying to swap
background images but it won't work. Any ideas?

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" >
  <mx:Script>
  <![CDATA[            
  function changeStyle() : Void 
      {         
mx.styles.StyleManager.styles.global.setStyle("background-image",
'backgrounds/redStripe.swf');
                  }
  ]]>
 </mx:Script>
 <mx:Style> 
  global { background-image: 'backgrounds/industrial.swf';
font-family: Helvetica; font-size: 12pt}       
 </mx:Style>
 <mx:Panel>
  <mx:Button label="Change Image!" click="changeStyle();"></mx:Button>
 </mx:Panel>
</mx:Application>



I also tried in my method passing in the following 'myRedBG' embedded
image var and that didn't work either.

[Embed(source="backgrounds/redstripe.swf")]
var myRedBG:String;

Thanks in advance for any help. I even tried this with basic
background coloring changes and couldn't get it to work so I feel I'm
missing something fundamental here.
