GUI building troubles

Maya
1

I am trying to make the switch from MEL to python. I am trying to build a simple UI for one of my scripts and I am having some trouble.

import maya.cmds as m
from functools import partial
 
 
def createCtrl():
    print "hello world"
 
 
class ui():
 
    def __init__(self, winName="ctrlLibWin"):
        self.winTitle = "Controller Library"
        self.winName = winName
 
    def create(self):
        if m.window(self.winName, exists=True):
            m.deleteUI(self.winName)
        m.window(self.winName, title=self.winTitle)
        self.mainCol = m.columnLayout()
        self.btnA = m.button(l = "Create Controller", c = partial(createCtrl, self))
        self.rBox = m.checkBox(l = "Red", v = 1, onc = self.rOn)
        self.gBox = m.checkBox(l = "Green", v = 0, onc = self.gOn)
        self.bBox = m.checkBox(l = "Blue", v = 0, onc = self.bOn)
        self.yBox = m.checkBox(l = "Yellow", v = 0, onc = self.yOn)
        m.showWindow( self.winName )
        m.window(self.winName)
 
    def rOn(self):
        print "hi"
        #m.checkBox(self.gBox, v= 0, e=True) 
        #self.gBox = m.checkBox(e=True, v = 0)
        #ui.create.bBox(e=True, v=0)
        #ui.create.yBox(e=True, v=0)
 
    def gOn(self):
        print "hello"
        #ui.create.yBox(e=True, v=0)
        #ui.create.bBox(e=True, v=0) 
        #ui.create.rBox(e=True, v=0)
 
    def bOn(self):
        print "hello"
        #ui.create.gBox(e=True, v=0)
        #ui.create.yBox(e=True, v=0)
        #ui.create.rBox(e=True, v=0)
 
    def yOn(self):
        print "hello"
        #ui.create.gBox(e=True, v=0)
        #ui.create.bBox(e=True, v=0)
        #ui.create.rBox(e=True, v=0)
 
 
inst = ui()
inst.create()

When I run the script and toggle the "Red" checkbox, i get the following error:

# Error: rOn() takes exactly 1 argument (2 given) #

I am not giving the rOn() method any arguments as far as I can tell.

I am also getting the error:

# Error: RuntimeError: file <maya console> line 26: Object's name 'ctrlLibWin' is not unique. #

The script deletes the window if there is already one active, so I don't think I should be getting that error?
Any assistance would be appreciated.

I editted your post a bit, the indentation got lost so i needed to recreate the scripts indent too. So please check that ist like you intended.

I am not giving the rOn() method any arguments as far as I can tell.

Its a callback, they have rules and in this case they pass the name of the event caller. So yes you ARE calling it with many arguments by inference that maya does, even if yoou think you do not. Make your events accept the extra variable input

  # Error: RuntimeError: file line 26: Object's name 'ctrlLibWin' is not unique.

Well you are callintg window a second time on line 26 and you should not

PS you have other bugs too.
