Isolateselect Toggle

[pixl]

Hi all:
I'm trying to write a simple isolateSelect toggle.
I have it partially working, but it doesn't update the selected geometry. While this could be a good feature to have (storing a set of visible objects/components), I'd like to get it working "normally".
Here's the proc. Based on using the viewport menus to do this, I don't think it should require the "loadselected" line.
CODE
     global proc pixl_isolateSelected() {
          string $curPanel = getPanel -up; //Get cam under pointer
          print ($curPanel+"\n");

          // If isolateSelect is 0, its disabled
          if (isolateSelect -q -state $curPanel) isolateSelect -state 0 $curPanel;
          else
          {
              isolateSelect -state 1 $curPanel;
              isolateSelect -loadSelected $curPanel;
          }

      }// end pixl_isolateSelected()
Anyone see what's wrong?
Thanks.

For anyone interested, here's the fix.
enableIsolateSelect is not in the manual...

CODE
global proc pixl_isolateSelected() {
       string $curPanel = getPanel -up; //Get cam under pointer

       // If isolateSelect is 0, its disabled
       if (isolateSelect -q -state $curPanel)
       {
           enableIsolateSelect $curPanel 0;
           isolateSelect -state 0 $curPanel;
       }
       else
       {
           enableIsolateSelect $curPanel 1;
           isolateSelect -state 1 $curPanel;
       }
   }// end pixl_isolateSelected()

or, more efficiently (thanks to JH at CGTalk):

CODE
global proc pixl_isolateSelected()
{
     string $curPanel = getPanel -up; //Get cam under pointer
     enableIsolateSelect $curPanel (!isolateSelect -q -state $curPanel);
}
