[ka-Map-users] Does there exist any plotting funtions yet?

[Paul Spencer]

Clark, its just an image.  You can add an onclick if you like, its  
nothing to do with ka-Map specifically.

img.onclick = myOnClick;

function myOnClick( e )
{
     e = window.event?window.event:e;
     alert( 'img clicked' );
}

other tricks would be:

img.style.cursor = 'help';
img.onmouseover = myMouseOver;
img.onmouseout = myMouseOut;
etc ...

If you want to make it work with partially transparent images, you  
will need to create an imagemap and put the onclick in the imagemap.   
That's just normal HTML stuff, I'm sure there are good tutorials on  
the web for it.

re dialog boxes, you can design your own in a div and in the onclick  
call the addobjectgeo to put it on the map. One thing I didn't  
mention is that you can define an offset value to correctly align  
images or other html elements

img.xOffset = -10;
img.yOffset = -10;

would anchor an image 10 pixels from the left and top edge.  This is  
important depending on your image design.

Cheers

Paul
