[mapguide-users] gain access to mapFrame divs for javascript drawing?

[Jonathan Manafi]

I have some javascript that initializes a jsGraphics object when my 
taskPane loads. Currently, it loads in a div within the taskPane. And 
before the page loads, I have a document.onkeydown and 
parent.parent.mapFrame.onkeydown set to a function to capture key 
presses and then do something. I have gotten the taskPane to recognize 
mouse movements and mouse clicks that are within the mapFrame, and 
currently, I use those to draw in the taskPane. I had tried what you 
said already, and I found the map table and inserted my own div. To test 
at first, I had put some text inside to see where(if at all) it would 
show up, and within the 'map' table, it showed up on top of the map. 

However, if I try to access it dynamically, after everything has loaded 
it seems, I cannot. I have something like
<code>
var map;
var divID;
var jg;
.
.
.
function init() {
  map = parent.parent.document.getElementsByTagName('frame')[1];
  divID = map.contentDocument.getElementById("mapSpace");
  jg = new jsGraphics(divID);
}</code>

And when my code gets executed, the taskPane turns to a blank page, and 
firebug throws numerous errors when I mouseover the map. The error it 
seems to be giving me is 'clicked is not defined', which is a global 
variable that has been declared and initialized.

Am I unable to draw in the mapFrame once it has already been loaded?

Also, somewhat unrelated, is IE7 not able to capture mouse movement or 
key presses within the mapFrame from the taskPane? It doesn't seem to 
react the same way as Firefox.

Thanks for any help.
