在窗口中创建动态按钮

我试图根据场景中存在的灯光数量在窗口中创建按钮。当我按创建按钮我得到这个错误（＃RuntimeError：没有指定对象名称＃。）：在窗口中创建动态按钮

Traceback (most recent call last): File "C:\Program Files\Autodesk\Maya2015\Python\lib\site-packages\pymel\internal\factories.py", line 779, in callback res = origCallback(*newargs)

我有点坚持了下来，我无法找到我问题的解答。这里是代码：

import maya.cmds as cmds 
import maya.mel as mel 
import pymel.core as pm 

class createWindowClass(object): 
    def __init__(self, *args): 
     pass 
    def show(self): 
     self.createWindow() 

    def turnOn(totalLgt, *args): 
     print "Enter turnOn" 

    def turnSolo(totalLgt, *args): 
     print "Enter turnSolo" 

    def updateList(name, totalLgt, *args): 
     print "update %s" % name 

     self.button = pm.button(label="ON", e=True, command = lambda *args: turnOn(totalLgt)) 
     self.button = pm.button(label="SOLO", e=True, command = lambda *args: turnSolo(totalLgt)) 

    def lightLst(*args): 
     totalLgt = 0 

     #list all lights in scene 
     lis = pm.ls(type='light') 
     print lis 
     for lgt in lis: 
      totalLgt += 1 
      nameLgt = lgt.longName() 
      name = nameLgt.split("|")[1] 
      print name 
      updateList(name, totalLgt) 

    #CREATE WINDOW 
    def createWindow(self): 
     windowID = 'Light Control' 
     if pm.window(windowID, exists = True): 
      pm.deleteUI(windowID) 

     pm.window(windowID, title = "Modify Lights", width = 100, sizeable = True) 
     pm.rowColumnLayout(numberOfColumns=1, columnWidth=[(10,120)], columnOffset=[10,"right",5]) 
     pm.text(label=" ******** Light list ******** \n") 
     pm.button(label="CREATE", command = lightLst) 
     pm.text(label= " \n ***************************** \n ") 
     window_obj = pm.window(windowID) 
     window_obj.show() 

cls = createWindowClass() 
cls.show()

如果有人可以带来一些光它，我真的会赞赏它！

你必须写pm.button(label="CREATE", command = self.lightLst)，你必须通过self作为在类中的方法，第一个参数。

谢谢！但不是真正的，如果我得到它的权利我加我自己的方法，但现在当它进入updateList我得到这个错误：＃RuntimeError：控件必须有布局。在窗口中找不到布局：＃ – Urd

在'lightLst'方法中，您还必须编写'self.updateList（name，totalLgt）' –

yes！已经这样做也<>（斯里我忘了说） – Urd
