add the event listener to link

Jun 26, 2012 3:22 AM

I am trying to trigger an event as image link is modified in InDesign file, using action script API in csaw lib. But it's thowing the error:

 

invalid value for parameter 'handler' of method 'addEventListener'. Expected File or JavaScript Function, but received nothing.

 

here is my code to add and handle the event:

 

 

tempLink.addEventListenerLink("afterAttributeChanged", handleLinkModified);
 
 
 
private function handleLinkModified(event:com.adobe.indesign.Event):void
  {
  trace("From link handler: LINK modified");
  }
 

 

I got this idea from one of John Hawkinson Thread: http://forums.adobe.com/message/4049418

Can someone let me know what''s going wrong with my logic?

 

Thanks

Mac

    You cannot use Actionscript functions as event handlers directly.

     

    You'll need to use the IDScriptingEventAdapter.

    If you are using Extension Manager, right click on the project and select Properties. Select "CS Extension Builder Libraries" on the left side. Select the Host Adapters tab and check Adobe CSHA InDesign.

     

    You should then be able to import IDScriptingEventAdapter and then you do something like this:

     

    IDScriptingEventAdapter.getInstance().addEventListener(eventName,handl erFunction);

    Yeah, using that way I'm able to add event listener, but the point here is I need to add that event listener to specific image link which may be modified.

     

    But still I'm in testing process will get back to you soon.

     

    Thanks a lot for your valuable help

    You cannot attach events to specific objects. Not in JS and not is AS.

    Thanks Harbs, for your valuable update, Is there any work around to get the information if any image link get modified ?

     

    My objective is to update the link in InDesign file automatically, if any link is modified outside the InDesign.

    Attach the event listener to the document or application and check the links when it fires...
