not in Tk at present AFAIK, but there's certainly carbon events 
generated for minimization, c.f. CarbonEvents.h:

   /*
    * Notification that the window is about to collapse. Available in
    * Mac OS X 10.1 and later.
    */
   kEventWindowCollapsing        = 86,

   /*
    * Notification that the window has successfully collapsed.
    */
   kEventWindowCollapsed         = 67,

   /*
    * Notification that the window is about to expand. Available in Mac
    * OS X 10.1 and later.
    */
   kEventWindowExpanding         = 87,

   /*
    * Notification that the window has successfully expanded.
    */
   kEventWindowExpanded          = 70,

It should be possible to implement Tk access to these via a small C 
extension, e.g. it wouldn't be hard to add handlers that pass these 
carbon events along as Tk events (probably best to use virtual events). 
The -ing events can prevent collapse/expand, I don't know if that would 
be useful/usable in Tk.

There are all sorts of other events in CarbonEvents.h that would be 
interesting to have access to from Tk, maybe we should think about some 
type of generic script level access to InstallEventHandler(), to enable 
us to create e.g. additional virtual events that can be bound to?
I think this could also be implemented in an extension in a first 
instance, and maybe moved into the core if it turns out to be useful.

Cheers,

Daniel
