Subject RE: [FlexJS] PopUp implementation
Date Thu, 24 Oct 2013 17:56:46 GMT
Hi Alex,

Sorry I missed the inline responses. Reading your response & Peter's I am better enlightened
:D 
I will refractor the code & advice when it's in a state where its near ready, I guess
popup class would vanish now.

Tabcatcher is for catching the tab key & distributing focus to the popup children rather
than the background stuff, it's a more vanity thing but I need it for something I am trying
to do.

Thanks,
Pratyoosh

Subject: Re: [FlexJS] PopUp implementation 

Hi Pratyoosh,

I had replied to various portions of your email in my previous reply.  Not sure if you saw
that or not.

Are you ok with my checking in everything except for the change to Alert?

What is a "tabcatcher"?

Thanks,
-Alex
