Are any of the images showing up as there
are no embed calls. ?
What about just setting the styles in a
css file externally and changing the styleName on the fly by binding the
bgimage to a variable?
Someone can correct me here, but isn’t
setStyles one of the most intensive processes due to the notifications to each
item. Going to the global, I would suspect wouldn’t be as bad – but
I really could just be talking out of my ass. Its been known to happen.
Also, I’ve done the below in 2- not
sure about 1.5.
Or you could do something like( I did
these recently for a cell rendered and worked like a charm)
<<mx:Application
xmlns:mx="http://www.macromedia.com/2003/mxml"
backgroundImage=”{sourceItem}” >
<mx:Script>
<![CDATA[
[Embed(source="assets/image.png")]
var
graphicImage:Class;
[Embed(source="assets/image2.png")]
var
graphicImage2:Class;
[Bindable]
public var sourceItem:Class;
function changeStyle() : Void
{
sourceItem=graphicImage2
}
]]>
</mx:Script>

Subject: [flexcoders] Unable to
Dynamically Changing BG image
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.
