The Flex snippet below listens for fullscreen events so that you can react and change layout, or whatever, when changing screen modes. One subtle tidbit to remember is that to set up the listeners you have to wait for applicationComplete. If you use creationComplete you’ll get a runtime error.

Note: I got most of this code off of some other tutorial and modified it. Now I don’t know where the source came from. If it’s you then please comment so that I can give you some credit.

Addendum: In the comments Jared was nice enough to point out the entry at FlexExamples.com that was the inspiration for this post.

To read the value of a FlashVar(s) use the following in your creationComplete handler.

_myNumber = Application.application.parameters.myNumber;

And the Javascript snippet would look like this if you using the default AC_FL_RunContent method.

"FlashVars", "myNumber=123",

Or for multiple variables:

"FlashVars", "myNumber=124&myString=polyGeek",

And if you’re using SWFObject then the Javascript would look something like this:


<script type="text/javascript">
var flashvars = {
myNumber: "123.456",
myString: "polyGeek" };

swfobject.embedSWF( '${application}.swf',
'${application}_div',
'${width}', '${height}',
'9.0.45',
'expressinstall.swf',
flashvars,
{bgcolor: '#ffffff', menu: 'false'}, {id: '${application}'});
</script>
