我想在Maya中制作一些代码，如果它会在下面的脚本示例中引起任何混淆，我很抱歉。问题是我想制作我的自定义PyQt类，后来在我的布局中用作Widget，但是我对这个东西缺乏知识，导致错误
# RuntimeError: '__init__' method of object's base class (test) not called. #
我读了几个关于该错误的主题，人们建议用super（）修复它。我试图把“super（）”，然后我收到这个错误：
# TypeError: PySide2.QtCore.QObject isn't a direct base class of test #
有人能为我清楚这件事吗？

当你创建一个类时，你可以选择继承另一个对象，在这种情况下可能是QDialog，因为它是你工具的主窗口。仅仅继承它是不够的，你必须调用QDialog的构造函数才能正确初始化，你可以用super来做。
使用super，您可以选择从您继承的类对象中运行方法。它看起来像这样：super(YOUR_CLASS_NAME, INSTANCE).METHOD_TO_RUN(PARAMETERS_TO_PASS)。所以更具体地说，运行你的__init__将是：super(testUi, self).__init__(parent)，这将解决它。
这可能是一个糟糕的解释，所以请谷歌super更好的例子。
我对您的脚本进行了一些编辑以简化它并在其中留下一些注释：
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(QtWidgets.QDialog): # Need to inherit from a `QObject`
def __init__(self, parent=None): # It's typical to include the `parent` parameter and pass that through `super`.
# If nothing was passed for parent, default to Maya's main window.
if parent is None:
parent = getMayaWindow()
super(testUi, self).__init__(parent) # Call `super` with the class's name, testUi, and its instance, self.
self.window = 'vl_test'
self.title = 'Test Remastered'
self.size = (1000, 650)
self.create() # Just automatically call create in the instance's constructor.
def create(self):
if cmds.window(self.window, exists=True):
cmds.deleteUI(self.window, window=True)
self.setWindowTitle(self.title)
self.resize(QtCore.QSize(*self.size))
self.testik = test(self) # Add `self.` so it belongs to this instance.
self.mainButton = QtWidgets.QPushButton()
self.mainLayout = QtWidgets.QVBoxLayout() # QVBoxLayout seems to give a better result.
self.mainLayout.addWidget(self.testik)
self.mainLayout.addWidget(self.mainButton)
self.setLayout(self.mainLayout) # Don't forget to make this widget actually set to this layout and use it.
class test(QtWidgets.QFrame):
def __init__(self, parent=None, maya_transform_nodes=[]):
super(test, self).__init__(parent) # Call `super` with the class's name, test, and its instance, self.
self.setMinimumWidth(300)
self.setMinimumHeight(300)
self.setStyleSheet("QWidget {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)
v = testUi()
v.show() # Call show to show it!
我是否正确地假设你正在尝试构建一个synoptics？如果是，您可能需要检查QGraphicsView以填充包含项目的窗口并处理大部分逻辑。否则你将不得不100％自己做，这可能很有趣，但很多额外的工作。
