Re: [flexcoders] Take two: dynamic asset creation

[Arul]

Dear Ian,

Thanks for the links

Right now I'm stuck in the same place as Josh Tynjala . old school style 
Function prototypes are not treated as Class. since flex components expect a 
class it fails
But I'm going to dig further in the morning (now its 1 am in Singapore)

Regards,
Arul

  Thanks Arul,
    The more I delve in to this and experiment with it the more I'm beginning 
to think it's not possible.

  Ben Stucki has an interesting post on a similar solution:
  http://blog.benstucki.net/?p=42

  But it relies on you needing to know exactly which component container the 
resulting object is destined for, and that won't work in TileLists (because 
ItemRenderers get reused). 

  Josh Tynjala has a slightly different solution:
  
http://www.zeuslabs.us/2007/09/28/actionscript-3-bitmap-image-classes-with-functions-and-loaders
 

  But it hits the same issue that I did, which is that in AS3 Function!=Class 
any more.

  It feels like it _ought_ to be easy.

  If it's really true that we can't use runtime-created assets with the Flex 
framework without handrolling a load of different ItemRenderers or creating our 
own subclasses of the Flex components, then that's very depressing and seems 
ill-thought-out. :-( 

  Cheers,
      Ian

    Dear Ian,

    I understand your use-case, I also needed something similar

    Let me do a quick experiment and get back to you on this

      Here's an easier way to explain the problem I posted about earler.

      If I create some BitmapAssets manually rathern than using embed:

      var b1:BitmapAsset=new BitmapAsset(someBitmapData1);
      var b2:BitmapAsset=new BitmapAsset(someBitmapData2); 
      var b3:BitmapAsset=new BitmapAsset(someBitmapData3);

      How do I then pass them to something like a TileList, which expects an 
icon property of type Class:

      var rowData:Object={label:"Some Label",icon:WhatGoesHere}; 

      Where WhatGoesHere can't be BitmapAsset (that just produces an empty 
bitmap). Nor can it be b1, because that's not of type Class.

      The goal here is to achieve this without creating a new ItemRenderer. 

      Thanks in advance,
          Ian
