[Chameleon] Window focus

[Paul Spencer]

Scott,

Chameleon does not do this (yet) although I think it would be a decent 
enhancement to the way all popups work in chameleon.

The way to do it is to preserve a handle to the open window.  In the 
code that opens the popup, you should have something like:

wh = window.open( .... );

The code should probably read something like:

//globally defined unique handle
var whMyPopup = null;

function myPopup()
{
     if (whMyPopup != null)
     {
         //raise existing window
         whMyPopup.focus();
     }
     else
     {
         //open new window
         whMyPopup = window.open( ... );
         whMyPopup.onclose = "window.opener.whMyPopup = null;";
     }
}


without some experimentation, I'm not sure if the onclose thing will 
work.  There are other ways to do that, though ...

Cheers,

Paul
