【问题描述】：

我正在尝试以 OOP 方式制作我的 PyQt5 GUI，例如窗口类和按钮类我真的很困惑如何制作它。这是我的代码，我尝试制作按钮类。我的目标是为窗口中的每个项目创建类

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
     def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        #making Pushbutton
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(180, 210, 93, 28))
        self.pushButton.setStyleSheet("QPushButton::setCheckable(bool)")
        self.pushButton.setObjectName("pushButton")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)
        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
       self.pushButton.setText(_translate("MainWindow", "PushButton"))
# here I'm trying to make Buttom class
class Button(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super(Button, self).__init__(parent)


# Main function
if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

【问题讨论】：

抱歉，您的问题确实不清楚（而且似乎也不完整）。你能澄清一下你想要达到的目标吗？
我正在尝试将窗口中的所有 itams 写为类
我不确定我理解你的意思。您想为您正在使用的 each 小部件创建子类吗？这是什么原因？
是的子类我觉得会更好更优雅
@Izzo 更好更优雅？我不认为那是真的。如果要创建自定义QPushButton然后继承自QPushButton，然后将self.pushButton = QtWidgets.QPushButton(self.centralwidget)改为self.pushButton = Button(self.centralwidget)
