The standard order of events is:

  1. The shutter item's button sends a SEL_COMMAND message
     to the shutter;

  2. The shutter opens the correct shutter item;

  3. The shutter sends a SEL_COMMAND message to its (the
     shutter's) message target.

So if you're just wanting to be notified when the user clicks on a 
particular shutter item to open it you should just catch the SEL_COMMAND 
message from the shutter directly, i.e.

     shutter = FXShutter.new(...)
     shutter.connect(SEL_COMMAND) do |sender, sel, which|
       puts "just opened shutter item no. #{which}"
     end

Hope this helps,
