  fireEvent is useful for sending data between js files and windows.
  you need to do something like this…
  to fire an event:

  Ti.App.fireEvent('foo', {name:'bar'});
  

  and to listen for that event and recieve the data:

  Ti.App.addEventListener('foo', function(data) 
  { 
       var name = data.name; 
  });
  

  var name will be equal to 'bar'.

• Too bad I'm not at my Mac right now. My Win machine here at work ran it nicely in the Android emulator. I got the "someEvent" message in the Titanium Developer console.

  The only difference is that I used var win=Ti.UI.currentWindow() instead of creating and opening a new window.

• (Ignore the parens at end of currentWindow in my prev post.)

• @Steve: Yes I happen to know how to call fireEvent from the Ti.App module. And yes it's useful when sending messages between windows, webviews, etc. But the docs is actually saying a lot more.

  Under Ti.UI module, there are 3 common methods across all objects: addEventListener, removeEventListener and fireEvent. So does that mean I can call fireEvent in any view? UIView? TableView? ScrollView?

  @Bill: My code above is for the app.js file that is why I do not need to access Ti.UI.currentWindow. But following your suggestion still throws an error.

  Here's what I'm trying to do:

  • create a view as a container
  • create more views as children of the container above
  • depending on what happens inside the container, i want to manually dispatch a custom event from the container so a window-level listener can listen to that custom event

  I hope I made it clearer. Thanks Steve and Bill! :)

• Sorry. My unordered list did not show as bullets. This formatting sucks.

• So I'm at my Mac now, and the code runs without error (I pasted exactly your code into an empty app.js). So no error, BUT it also doesn't fire the event.

  Apparently this is a known issue, with a ticket opened 2 days ago.

  The problem seems to be with custom events on views – exactly what you want to do. :( Hopefully they'll get to it soon. If you create an account at lighthouseapp, you can "watch" the ticket.

• Bill, glad you found the ticket to this issue. It seems like it works in Android but not in iPhone. I'll should start watching that ticket.

  Cheers!
