Mike,
Sorry I should have provided some doc strings ;) The magic in my
example is here:-
## this function is called when you create the Button widget
def launchit(external, filename):
external_short = os.path.split()[1]
## this inner function has access to the outer functions
## namespace
def real_launchit():
os.spawnl(os.P_NOWAIT, external, external_short, filename)
## return a reference to the inner function
## this 'reference to a function' will be called when the button
## is pressed
return real_launchit
on re-reading the example I noticed I had made a couple of typoes
Cheers
Martin
