Python 如何将“模型”面板添加到maya PySide中在designer中创建的布局

我正在中创建脚本，我想在QtDesigner中创建的grig布局中放置模型面板

模型面板必须放置在红色区域。我试过了

cmds.setParent(self.LAY_grid_modelEditor)
cmds.modelPanel('testEditor', cam='persp')
cmds.setParent('..')

但是得到了错误

运行时错误：未找到setParent:对象“”

我在Maya 2015中使用PySide

任何帮助…

此代码实际上是我从中获取的，它将显示如何在pyqt中嵌入maya gui。同样的方法也可以用于pyside。我修改了这个示例代码，现在它将加载一个modelPane

import maya.OpenMayaUI as apiUI
from PyQt4 import QtGui, QtCore
import sip

def getMayaWindow():
    ptr = apiUI.MQtUtil.mainWindow()
    return sip.wrapinstance(long(ptr), QtCore.QObject)

def toQtObject(mayaName):
    '''
    Given the name of a Maya UI element of any type,
    return the corresponding QWidget or QAction.
    If the object does not exist, returns None
    '''
    ptr = apiUI.MQtUtil.findControl(mayaName)
    if ptr is None:
        ptr = apiUI.MQtUtil.findLayout(mayaName)
    if ptr is None:
        ptr = apiUI.MQtUtil.findMenuItem(mayaName)
    if ptr is not None:
        return sip.wrapinstance(long(ptr), QtCore.QObject)

class MayaSubWindow(QtGui.QMainWindow):
    def __init__(self, parent=getMayaWindow()):
        super(MayaSubWindow, self).__init__(parent)
        self.modelPne = cmds.modelPanel('testEditor', cam='persp')
        qtObj = toQtObject(self.modelPne)
        self.setCentralWidget(qtObj)

myWindow = MayaSubWindow()
myWindow.show()
