How do i add “addEventListener” to this custom class?  
i want to add Two addEventListener,

1. when the 'calculateProgress is function is modifying ‘p’ property, i want the flash document to get that number for each update.

2. when the loading is complete, i want to trigger the oncomplete function. i did this by passing the function to the object parameter, but i would like to use addEventListener.  
here the following code is the way i achieved this.

[COLOR=#000000] **var** [/COLOR] [COLOR=#0000FF]list[/COLOR]:[COLOR=#0000FF]Array[/COLOR] = [COLOR=#000000][[/COLOR][COLOR=#FF0000]“pastelar.swf”[/COLOR],[COLOR=#FF0000]“frankGothicBook.swf”[/COLOR][COLOR=#000000]][/COLOR];  
[COLOR=#000000] **var** [/COLOR] loader:FontLoader = [COLOR=#000000] **new** [/COLOR] FontLoader[COLOR=#000000]([/COLOR][COLOR=#0000FF]list[/COLOR], [COLOR=#000000]{[/COLOR]onComplete:done[COLOR=#000000]}[/COLOR][COLOR=#000000])[/COLOR];  
loader.[COLOR=#0000FF]load[/COLOR]COLOR=#000000[/COLOR];

addEventListener[COLOR=#000000]([/COLOR]Event.[COLOR=#000080]ENTER\_FRAME[/COLOR], loop[COLOR=#000000])[/COLOR];  
[COLOR=#000000] **function** [/COLOR] loopCOLOR=#000000[/COLOR]:[COLOR=#0000FF]void[/COLOR]  
[COLOR=#000000]{[/COLOR]  
[COLOR=#0000FF]trace[/COLOR]COLOR=#000000[/COLOR];  
[COLOR=#000000]}[/COLOR]

[COLOR=#000000] **function** [/COLOR] doneCOLOR=#000000[/COLOR]:[COLOR=#0000FF]void[/COLOR][COLOR=#000000]{[/COLOR]  
removeEventListener[COLOR=#000000]([/COLOR]Event.[COLOR=#000080]ENTER\_FRAME[/COLOR], loop[COLOR=#000000])[/COLOR];  
[COLOR=#000000]}[/COLOR]

but instead doing that, i wanna be able to this.
