Maya API/ PySide2 ，wrapInstance 中的参数错误

Question

尝试学习一些PySide2 for Maya，但是PySide2还没有明确的文档，所以在网上搜索后再次来这里寻求帮助......

我会直奔问题——

from PySide2 import QtWidgets, QtGui
import maya.cmds as cmds
import maya.OpenMayaUI as mui
import shiboken2

def getMayaWindow():
    pointer  = mui.MQtUtil.mainWindow()
    if pointer is not None:
        return shiboken2.wrapInstance(long(pointer), QtWidgets)

错误：TypeError：文件第 9 行：使用错误的参数类型调用了“wrapInstance”：

wrapInstance(long, module)

支持的签名：

wrapInstance(size_t, PyType) #

最好的问候！

Answer 1

您应该尝试通过以下方式导入模块：

import maya.cmds as cmds
from PySide2.QtCore import * 
from PySide2.QtGui import *
from PySide2.QtWidgets import *
import maya.OpenMayaUI as omui

try:
    from shiboken import wrapInstance
except:
    from shiboken2 import wrapInstance


def getMayaWindow():    
    pointer = omui.MQtUtil.mainWindow()
    if pointer is not None:
        return shiboken2.wrapInstance(long(pointer), QWidget)

getMayaWindow()
