[Chameleon] Widgets or JSAPI

[Seiple, Timothy E]

I'm starting to see the light... For clarification though:

The order of events will be 1) Use the customized Query widget to get
and store the {x,y} in variables rather than display results.  Then use
a Link widget to get back to the calling application, taking along the
x,y variables somewhere in the http header.  Is this right?

I did not see ON_QUERY in the event details section of the chameleon
documentation.  How did you know about this event?  Are there more that
I am missing?

After some deep Chameleon soul searching I remembered the Customizing
Query Results:

This is a relatively simple method of accomplishing your task without
having to create a widget.  Basically, you will have a link widget
which, when used, gets intercepted by the Global Event Manager.  At this
point you can call anything you want in javascript.

You shouldn't have to get e or event for this IF you include the
CursorPos widget (for X & Y).  In your js callback you will be able to
get the coordinates via the form variables:

document.formname.CursorPos_X.value
document.formname.CursorPos_Y.value

So, let's say that in your body onload you specify:

goEventManager.registerForEvent( 'ON_QUERY', 'cbLocation' );

so that when you perform a 'query' the following gets called:

function cbLocation()
{
      var nX = document.formname.CursorPos_X.value;
      var nY = document.formname.CursorPos_Y.value;
      window.opener.document.formname.nXLocation.value = nX;
      window.opener.document.formname.nYLocation.value = nY;
      self.close();
}

Although I haven't tested this code it should work.  CursorPos_X and
CursorPos_Y do all the work for you in getting the coords.  You just
have to reference them and pass them back to your opener.

Make sense?
