如何在我的PySide（Maya）脚本中解决“非序列迭代”问题

Question

I am trying to make PySide Ui in Maya looking at different examples of codes, but mine doesn't work, Problem is that I am getting

#Traceback (most recent call last):
#   File "maya console", line 69, in <module>
#   File "maya console", line 32, in create
#   File "maya console", line 61, in __init__
#   File "maya console", line 65, in set_items
# TypeError: iteration over non-sequence # 

I read few topics about this error and seems to be a problem when people try to iterate thru instance, but since my knowledge in Object-Oriented programming still lacking , I am confused why is it happening in my script.

 from PySide2 import QtGui, QtCore, QtWidgets from shiboken2 import wrapInstance import maya.OpenMaya as om import maya.OpenMayaUI as omui import maya.cmds as cmds import os, functools def getMayaWindow(): pointer = omui.MQtUtil.mainWindow() if pointer is not None: return wrapInstance(long(pointer), QtWidgets.QWidget) class testUi(): def __init__(self): self.window = 'vl_test' self.title = 'Test Remastered' self.size = (1000, 650) def create(self): if cmds.window(self.window, exists=True): cmds.deleteUI(self.window, window=True) self.parentWindow = getMayaWindow() self.mainWindow = QtWidgets.QMainWindow(self.parentWindow) self.mainWindow.setObjectName(self.window) self.mainWindow.setWindowTitle(self.title) self.mainWidget = QtWidgets.QWidget() self.mainWindow.setCentralWidget(self.mainWidget) self.mainLayout = QtWidgets.QFormLayout(self.mainWidget) testIk = test(self) self.mainLayout.addWidget(testIk) self.mainButton = QtWidgets.QPushButton() self.mainLayout.addWidget(self.mainButton) self.mainButton.clicked.connect(partial(self.load_selected)) self.mainWindow.show() class test(): def __init__(self, maya_transform_nodes=[]): qWid = QtWidgets.QWidget() self.setMinW = qWid.setMinimumWidth(300) self.setMinH = qWid.setMinimumHeight(300) self.sss = qWid.setStyleSheet("border:1px solid rgb(0, 255, 0);") self.items = [] self.transform_move = QtGui.QTransform() self.transform_scale = QtGui.QTransform() self.prev_mouse_pos = QtCore.QPoint(0, 0) self.color = QtGui.QColor(0, 255, 50, 50) self.clicked_color = QtGui.QColor(0, 255, 50, 150) self.right_clicked_color = QtGui.QColor(255, 0, 0, 150) if maya_transform_nodes: self.set_items(maya_transform_nodes) def set_items(self, maya_transform_nodes): for path in maya_transform_nodes: print path v = testUi() v.create() 

Expected result would be - I get window , with button which doesn't function and small widget which I wrote in test().

In testUi.create you have:

testIk = test(self)

But self is just the class instance of testUi . It is a class, not a list. But it is being passed as maya_transform_nodes in test , which expects a list or other iterable. So either pass it a list (or other iterable), or remove the argument and let it default to [] .
