RE: [Flashcoders] Where to add eventListners in UIComponent classes?

2006-11-07 Thread Ben Smeets 
I might be getting it wrong but the following might help:

In working with components and using "placed onscreen in editor"
components, I always find myself needing to wait 1 frame before adding
the component event listeners. It seems the v2 components need 1
enterframe to fully initialize themselves.

The way I do it (very crude code, in no sense useable in a copy paste
sense)


Private function onEnterFrame() {
// Create this handler, which if all goes well
// will be called only once, but we know 100% sure
// we had at least 1 frame interval.
addHandlers();
} 

Private function addHandlers() {
// Clean up the onEnterFrame
delete this.onEnterFrame;

// Add all listeners here
myComponent.addEventListener("click", this);
}

Subject: [Flashcoders] Where to add eventListners in UIComponent
classes?

I have a component that has a couple Macromedia UI components used
inside of it. I have found that if I add my event listeners inside of
createChildren after I have added the UI components the events are not
added. I have also tried to add the events inside of the draw method. In
order to get the events to work properly I have to add them into my
onLoad() method. However this makes it so when I load the component I do
not get an accurate onLoad event from the component as the event
handlers have yet to be registered. Is there someplace that I am missing
that I should be placing all of my event registration in anything that
extends UIComponent? 

 

Thanks;

Wade Arnold

This seems to work reliably for simple decoration and composition into 
homemade widgets. Don't know if it will help you with building Adobe 
style 'components'...


function makeBtn():Void
{
   btnV2 = Button(btn_mc.attachMovie("Button", "btnV2", 0));
   if (btnV2.initializing == true){
   btnV2.watch("initializing", handleWatch, this);
   } else {
   onInt();
   }
}

private static function handleWatch(prop, oldVal, newVal, instance):Boolean
{
   if (newVal == false) instance.onInt();
   return newVal;
}

private function onInt():Void
{
   btnV2.addEventListener('click', doStuff);
   btnV2.setSize(WIDTH, HEIGHT);
   btnV2.enabled = true;
   ...
   btnV2.unwatch("initializing");
}
