PHP Code:

new GuiShowImgCtrl( "InvItem_0" )
{
  image = "x.png";
  width = 32;
  height = 32;
  x = 10;
  y = 10;
  
  this.itemName = "Guns/KABOOM!!!111!!";
  thiso.catchevent( name, "onMouseDown", "onItemSelected" );
} 


and later something like this:

PHP Code:

function onItemSelected( obj )
{
    for(temp.i=0;temp.i<player.weapons.size();temp.i++;)
    {
      if(player.weapons[temp.i].name == obj.itemName)
      {
        player.selectedweapon = temp.i;
        return;
      }
    }
} 


I believe that will work.
