menuItem calling modules

[vilkdage]

Hi, 

I have a pm.menu in which holds menuItems. In one of them I would like to call a QtWidget which was written inside the class:

def CreateMenu():
    ...
    toolUI = fileName.className()
    pm.menuItem(label="Tool", command=toolUI.run)

menuItem does not accept a function which calls class as it considers class as an argument (as far as I understand). The function inside the class that I want to run does not have any arguments.

the main menu was written in function, not as a class. I cannot change that. Is there a way to run a module inside menuItem?

Try this.

pm.menuItem(label="Tool", command=lambda _=None: toolUI.run())

What happens is, the menuItem will try and call your function with an argument (the index of the menu item itself? I forget), and this lambda will simply intercept and discard it. You could have written lambda: toolUI.run() but by having the lambda take an argument you allow the call to be repeated via the g key, like it normally would without the lambda.

Another option is to accept the argument in the run() function, something you discard.

Yet another option is to make a second “wrapper” function that you use solely for menus.

def run(_):
  return toolUI.run()

pm.menuItem(label="Tool", command=run)
