Dear Mirko,

use a lambda function as command for the button and pass a name or
number to that function,
this is a way to identify the clicked button:

  for file in os.listdir( dir ):
        tmp_func_load = lambda index=0, obj=self: obj.load(file)
        Button( load_dlg_frame, text=file, relief=GROOVE,
                command=tmp_func_load).pack()

def  load(self, filename):
    pass

I pack the whole stuff into a class, that's the reason for the selfs,
but
it works without it, too.

Markus
