[Chameleon] How do you set/get what tool is active with JSAPI?

[Ken Sanderson]

Thanks for the reply. Still struggling with the best approach and how to
go about it.

I could put a check in my click function that uses what you provided
below, and then use the cooresponding JSAPI function to do the action.
So for example:

if (document.forms[0].NAV_CMD.value == "ZOOM_IN"){
  oMap.ZoomInPos( goCWCJSAPI.mouseclick[0], goCWCJSAPI.mouseclick[1] );
}

I can do that for ZOOM_OUT, ZOOM_IN, and RECENTER. ZOOM_IN might be
tricky as I have to handle the rectangle drawing as well, but I think
doable. How would you do this for QUERY though, I don't see a JSAPI
method for that? Also do the functions like ZoomInPos() currently work?
I have them implimented, no errors, but also nothing happens.

Are there any other options that I should be looking at? Really all I
want is to add my own tool that will give me the coords from the map to
use in my own script.

Thanks again,

Ken

There isn't really a mechanism in the CWC JSAPI for determining which 
tool is active, but you can check:

if (document.forms[0].NAV_CMD.value == "ZOOM_IN")
{
}

Cheers,
