Re: Passing data between components - should one use nsEvent ?

[Johnny Stenback]

Are you trying to pass data along with the page load event that's 
already fired there, or are you thinking of adding code to fire an 
additional event from nsDocumentViewer::LoadComplete()? If you're adding 
new code to fire a new event I'd suggest you write a DOM event 
implementation and make that object carry your data (see 
nsXMLHttpProgressEvent for an example of how to write a new DOM event 
implementation). But no matter what sort of event you fire there I don't 
see how that'll ever make it into an OnStateChage() implementation since 
that's not driven by event code, that's called from internal code that 
sees internal state changes etc...

(please cc me directly on any replies as I don't read this group that 
often).

I see from the comments that an OnLoad/OnError event gets fired and I
was hoping to use the same nsEvent based idiom to pass my data around
but have had no success - is this the right approach or should I be
looking for a different way?
