Nope, that should be fine! I only mentioned the lambda way of dealing with it if you didn't want your callable to accept *args and/or **kwargs. I don't like to blanket add *args and **kwargs if it doesn't fit the design of my code. In a lot of situations the code I'm writing is being used in multiple places, calling via a menu just being one of those, so I don't like the menu influencing how I have to write the code.
In the above example you gave using a lambda it should have worked if you added parentheses after runThis: *cmds.menuItem(p=shotsMenu, l='Shot Setup', command=lambda *args, **kwargs: *runThis()*)* On Wed, Apr 23, 2014 at 9:36 AM, Tim Crowson <[email protected]> wrote: > Thanks guys!
