RE: [Flashcoders] dispatching events from a class = HELP
Hi, I'm also having problems with Events. Could someone give me a little
help on this issue?
The EventListener is firing fine, but its associated method CAN NOT call
another Class method. Why?
Here is the Main Class: (Here is the Problem)
import com.ultrafactor.LblButton;
class com.ultrafactor.TabBox extends MovieClip
{
private var tab_0:LblButton;
public function TabBox()
{
main();
}
private function main():Void
{
setButtonListeners();
}
// don't know why it takes so long...
// is there any other elegant way to do it??
private function setButtonListeners():Void
{
i=0;
this.onEnterFrame = function()
{
this.i++;
if(this.i==20)
{
delete this.onEnterFrame;
}
else
{
tab_0.addEventListener(release,this.clickTab);
}
}
}
private function clickTab(evtObj:Object):Void
{
trace(click);// WORK
this.test();// DO NOT WORK
}
//Can't call this Method!!!
private function test():Void
{
trace(test);
}
}
The used Classes:
import mx.core.UIObject;
import mx.core.UIComponent;
class com.ultrafactor.Button extends mx.core.UIComponent
{
private var initializing:Boolean = true;
private var autoRepeat:Boolean;

function Button()
{
super.init();
useHandCursor = true;
}
private function size(Void):Void
{

}
private function draw(Void):Void
{
if (initializing)
{

}
size();

You need to use a Delegate. As this is a question which comes up about one a week on this mailing list (not your, fault, I know!) I'm afraid I'm going to direct you to the Flashcoders Wiki page about the problem rather than answer you in full here... http://www.osflash.org/flashcoders/as2 Hope that helps, Ian On 11/13/05, Bruno Mosconi [EMAIL PROTECTED] wrote: Hi, I'm also having problems with Events.

Why delegate if the method is inside the same Class? thanks -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ian Thomas Sent: domingo, 13 de novembro de 2005 15:46 To: Flashcoders mailing list Subject: Re: [Flashcoders] dispatching events from a class = HELP You need to use a Delegate.

Re: [Flashcoders] dispatching events from a class = HELP
You need to use the Delegate in your addEventListener line - because you're passing clickTab to a completely different object, which will later call back to clickTab, but doesn't have the correct context. Passing this.clickTab isn't enough - passing Delegate.create(this,clickTab) should be enough. I know it's odd. This is changed in AS3.

Thanks!
