flex - Is it possible to use outside "<mx:script>" in "<mx:canvas>"? -


i got new project. , part of it, flex exist.

<mx: application xmlns:mx=...>    <mx:script>           import...             function a() {             }     </mx:script>      <mx:linkbar...>     <mxviewstack ...>         <mx:canvas id="1st" ...>  **[here]**  </mx:canvas>        <mx:canvas id="2nd" ...>  ... </mx:canvas>        <mx:canvas id="3rd" ...>  ... </mx:canvas>

** when viewstack calls canvas sequentially, a() has work.

is possible use function a() in **here**]?

or please let me know possible function or tag can used.

below example may you: -
