I think you should change the way you define the main class, so you keep
references to the class attributes;
it looks like your main class fires up a Tk() window, so it's probably best to
subclass Tk() :
class Main(Tk):# this doesn't really matter, but upper case letters are
generally preferrred for class names
def __init__(self, *args, **kw):
Tk.__init__(self, *args, **kw)
# at this point the Main() class practically is a Tk(), so it can be
handled just like a regular
# Tk() window from the outside; the "*args, **kw" construct allows to
pass an arbitrary amount of
# arguments and keyword arguments to the parent class. "self" is a
placeholder for the class instance
# that will be actually used in the code.
# To get a benefit over a normal Tk() window you can now start adding
attributes:
self.showquote = Label(self, text=random.choice(quotes.quote))
self.showquote.pack()
< etc. >
# of course you can use the parent classes methods on "self", too:
self.title("Quoter %s" % (about.ver))
self.minsize(300, 50)
# now you can add a button which uses a "class-specific" command:
self.switchbutton = Button, text="Switch quote",
command=self.switch_quote)
self.switchbutton.pack()
# finally the class method has to be defined:
def switch_quote(self):
newquote = get_the_new_quote()# it's up to you how to do this of course
self.showquote.configure(text=newquote)
Now the Main() class can be used like a regular Tk() :
root = Main()
root.mainloop()
And for something completely different:
be careful mixing pack(side = LEFT / RIGHT) with pack(side = BOTTOM / TOP),
you might not get the results you expected. For complex layouts you are
probably better off
using grid() ( or you will find that you have to use extra Frames to pack()
your widgets in.
I hope this helps
