python - 在 PySide2 应用程序中，如何获取 QWindow 的 ID？

Question

在 Maya2017 附带的 PySide2 版本中，winIdQWindow 类上的方法似乎丢失了：

w.winId()
Error: AttributeError: file <maya console> line 1: 'PySide2.QtGui.QWindow' object has no attribute 'winId' # 

有没有办法从现有的 QWindow 实例中获取这个值？

Answer 1

Andy's example works for me in both Maya2018 and the latest release of Maya2017, but throws an exception in at least the initial release of Maya 2017.

I expect the problem was caused by a bug in PySide2 that got fixed along the way.

Answer 2

我将 Maya 2018 用于 macOS 10.11.6。试试这个代码。有用。

from maya import OpenMayaUI as omui 

try:
  from PySide2.QtCore import * 
  from PySide2.QtGui import * 
  from PySide2.QtWidgets import *
  from PySide2 import __version__
  from shiboken2 import wrapInstance 
except ImportError:
  from PySide.QtCore import * 
  from PySide.QtGui import * 
  from PySide import __version__
  from shiboken import wrapInstance 

mayaMainWindowPtr = omui.MQtUtil.mainWindow() 
mayaMainWindow= wrapInstance(long(mayaMainWindowPtr), QWidget) 

w = QLabel("Hello, Window", parent=mayaMainWindow) 
w.setObjectName('Label1') 
w.setWindowFlags(Qt.Window)
w.show() 

输入后：

w.winId()

你会得到这样的东西：
