当我最大化窗口时，我的小部件不会替换

Question

如何在窗口最大化时重新定位小部件？

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")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(350, 100, 81, 21))
        self.label.setObjectName("label")
        self.label_2 = QtWidgets.QLabel(self.centralwidget)
        self.label_2.setGeometry(QtCore.QRect(270, 130, 81, 21))
        self.label_2.setObjectName("label_2")
        self.label_3 = QtWidgets.QLabel(self.centralwidget)
        self.label_3.setGeometry(QtCore.QRect(270, 160, 81, 21))
        self.label_3.setObjectName("label_3")
        self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit.setGeometry(QtCore.QRect(370, 130, 113, 20))
        self.lineEdit.setObjectName("lineEdit")
        self.lineEdit_2 = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit_2.setGeometry(QtCore.QRect(370, 160, 113, 20))
        self.lineEdit_2.setObjectName("lineEdit_2")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
        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.label.setText(_translate("MainWindow", "TextLabel"))
        self.label_2.setText(_translate("MainWindow", "TextLabel"))
        self.label_3.setText(_translate("MainWindow", "TextLabel"))


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_())

您可以在以下位置了解PyQt5中的布局管理：http://zetcode.com/gui/pyqt5/layout/

尝试作为一种选择：

import { Selector, t } from 'testcafe';

   class LoginPage {

       get emailTextBox() { return Selector('#EmailAddr'); }
       get passwordTextBox() { return Selector('#Password'); }
       get loginButton() { return Selector('#SignIn'); }

       async login(username, password) {
           await t
               .click(this.emailTextBox)
               .typeText(this.emailTextBox, username)
               .click(this.passwordTextBox)
               .typeText(this.passwordTextBox, password)
               .click(this.loginButton)
       }
   }
   export default new LoginPage();
