[Maya-Python] Re: Maya UI - I'm sure it's easy once one knows how.
Just to add a bit more: The below block of code is one I just stick
on my shelf, and drag it down to the script editor any time I want to
start a new window. Like Seth, I just modified it to add a button to
close the window as well.
The finicky bit are button commands, or any command executed from a
control: They only expect to execute a string, or a function *name*,
without args. Things get more complex if you want want to pass args
from your button to your command/method, and like Seth showed you can
use *args to help capture them on the method side. Furthermore, even
if you don't want to capture args from your command execution, Maya
likes to pass out a default value upon execution which your command
must be able to intercept, again, via *args. If you're interested in
the specifics of that, I have a couple tutorials\notes here:

I have not seen it posted so I thought I would mention there are other
options for passing callable functions as well. You can use a partial
function to create a callable function to a command.
Example:
from functools import partial
def myfunc(does, some=1, stuff='test'):
print does
print some
print stuff
part = partial(myfunc, 10, some=10, stuff='ten')
part()
# Result #
10
10
ten
# End Result #
By using the partial function you can pass a button a partial function
with whatever arguments you need to pass:
self.button = mc.button(label=Close Window, command=partial
(self.buttonCmd, 'pass', my='arguments', into='something')

[Maya-Python] Re: Maya UI - I'm sure it's easy once one knows how.
Yeh, you know, lambdas work often, but not always. I've found that if
I have a procedurally generated UI... say, looping to make a lot of
buttons, and each should have some unique argument passed into the
executed command, lambda will assign the same args to every button
(bad), but functools.partial will pass in the uniqe args (good). So I
sort of use a mix of the two depending on the situation. I haven't
tried troubleshooting why that is though ;)

I guess you can use a lambda also which I didnt know Eric. I gave you
