Signal function on complete of another function

Question

Argh.. This seems pretty easy but I cannot find information about this anywhere.  I might just be searching wrong..
Anyway, I'd like to signal a function to run when another function completes.
I am filling a scrollPane with some dynamic content and want it to resize once the content has filled in some dynamic text boxes.
I'd like to signal a resize function once the function that fills in the scrollPane completes.  I tried something like this but it does not seem I can add this sort of listener to a funciton.
scrollPanePopulate.addEventListener(Event.COMPLETE, scrollPaneResize);
I might be missing something obvious or just be headed down the wrong path.  Thanks in advance..

Answer 1

function scrollPanePopulate(event:Event):void{
//show scroll pane
     scrollPane.visible=true;
//create the temp variables
     var calledMarkerIndex=pntxml.row[pointindex].ID;
     var calledMarkerDate=pntxml.row[pointindex].DATE;
     var calledMarkerDescription=pntxml.row[pointindex].DESC;
     var calledMarkerContent=pntxml.row[pointindex].URL_OF_CONTENT;
     var imgSource:String = "<img src="+"'"+calledMarkerContent+"'"+"width='405'"+"height='280'"+"/>";
//fill in the text
     scrollPaneContent.scrollPaneImage.htmlText=imgSource;
     scrollPaneContent.scrollPaneText.htmlText="<font size='12' color='#ffffff'>"+calledMarkerDescription;
     scrollPane.update();
     scrollPane.verticalScrollPosition=(0);
and something like this would size my scrollPane to a reasonable size
function scrollPaneResize(event:Event):void{
//resize the scrollpane to content's size
     var imgHeight=scrollPaneContent.scrollPaneImage.height;
     var txtHeight=scrollPaneContent.scrollPaneText.height;
     var contentHeight=(imgHeight+txtHeight);
     scrollPane.setSize(510,(contentHeight+50));
Finally..  What I'll ultimatley do is set this up so that if the two componenent in my scrollPane are too large (height+height) then I'll have a maximum size that the scrollPane can attain
