Your callback function will be inside the event listener and not inside the MlEditmanager class. E.g. if you're listening for events in the Main class, you can have a function defined inside Main any way you want. Whenever that event is triggered, your function will be called.
You do not need any functions other than the ones declared in IEventListener to dispatch events from MlEditmanager. .p On Thu, Sep 30, 2010 at 12:31 PM, Harish Vardhan <[email protected]>wrote: > can i use call back function for example.. private var xyz:Function; > > how to use this? > > ------------------------------ > *From:* Pranav Negandhi <[email protected]> > *To:* [email protected] > *Sent:* Thu, September 30, 2010 5:34:52 AM > *Subject:* Re: [flex_india:31604] Call back functions in flex > > You can do this using composition.
