当我按下按钮时，PyQt5无法向窗体添加更多输入

Question

我在PyQt5中有一个表单，并添加了一些QLineEdits字段。在

当用户单击QPushButton时，我想以编程方式将QLineEdits字段添加到表单中，但当我运行应用程序并单击按钮时，我的应用程序不会向表单添加任何内容，也不会出现任何错误。在

那么，我该怎么解决呢？ 这是我的代码：

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_AnonForm(object):
   def setupUi(self, AnonForm):
      AnonForm.setObjectName("AnonForm")
      AnonForm.resize(500, 410)

      font = QtGui.QFont()
      font.setBold(True)
      font.setWeight(75)

      self.AnonTxt1 = QtWidgets.QLabel(AnonForm)
      self.AnonTxt1.setGeometry(QtCore.QRect(20, 10, 60, 20))
      self.AnonTxt1.setFont(font)
      self.AnonTxt1.setTextFormat(QtCore.Qt.RichText)
      self.AnonTxt1.setAlignment(QtCore.Qt.AlignCenter)
      self.AnonTxt1.setObjectName("AnonTxt1")

      self.AnonGroups = QtWidgets.QLineEdit(AnonForm)
      self.AnonGroups.setGeometry(QtCore.QRect(20, 30, 60, 20))
      self.AnonGroups.setFont(font)
      self.AnonGroups.setMaxLength(6)
      self.AnonGroups.setAlignment(QtCore.Qt.AlignCenter)
      self.AnonGroups.setObjectName("AnonGroups")

      self.AnonGo = QtWidgets.QPushButton(AnonForm)
      self.AnonGo.setEnabled(False)
      self.AnonGo.setGeometry(QtCore.QRect(400, 26, 80, 28))
      self.AnonGo.setFont(font)
      self.AnonGo.setCursor(QtGui.QCursor(QtCore.Qt.PointingHandCursor))
      self.AnonGo.setObjectName("AnonGo")

      self.retranslateUi(AnonForm)
      QtCore.QMetaObject.connectSlotsByName(AnonForm)

      self.AnonGroups.setValidator(QtGui.QRegExpValidator(QtCore.QRegExp('^[0-9]+$')))
      self.AnonGroups.textChanged.connect(self.AnonOnpercentInputChg)
      self.AnonGo.clicked.connect(lambda: self.AnonGoSim('AnonForm'))

   def AnonGoSim(self, name):
      _translate = QtCore.QCoreApplication.translate
      AnonForm.setWindowTitle(_translate(name, "Change Me - Anoujaa SAS"))

      font = QtGui.QFont()
      font.setBold(True)
      font.setWeight(75)

      self.AnonGroupsLui = QtWidgets.QLineEdit(AnonForm)
      self.AnonGroupsLui.setGeometry(QtCore.QRect(40, 60, 80, 40))
      self.AnonGroupsLui.setFont(font)
      self.AnonGroupsLui.setMaxLength(6)
      self.AnonGroupsLui.setAlignment(QtCore.Qt.AlignCenter)
      self.AnonGroupsLui.setObjectName("AnonGroupsLui")

   def AnonOnpercentInputChg(self, text):
      if text:
         self.AnonGo.setEnabled(True)
      else:
         self.AnonGo.setEnabled(False)

   def retranslateUi(self, AnonForm):
      _translate = QtCore.QCoreApplication.translate
      AnonForm.setWindowTitle(_translate("AnonForm", "King - Anoujaa SAS"))
      self.AnonTxt1.setText(_translate("AnonForm", "Grupos"))
      self.AnonGo.setText(_translate("AnonForm", "Go!"))

if __name__ == "__main__":
   import sys
   app = QtWidgets.QApplication(sys.argv)
   AnonForm = QtWidgets.QWidget()
   ui = Ui_AnonForm()
   ui.setupUi(AnonForm)
   AnonForm.show()
   sys.exit(app.exec_())

这是一个粗略的实现，我知道你正在尝试做什么。您需要添加一个可以添加QLineEdit的布局。widget也是widget

from PyQt5.QtWidgets import *

class Form(QMainWindow):

x = 1
def __init__(self):
    super(Form, self).__init__()

    self.setUI()

def setUI(self):
    self.lineEdit = QLineEdit()
    self.pushButton = QPushButton("Go")

    self.layout = QGridLayout()
    self.layout.addWidget(self.lineEdit,0,0)
    self.layout.addWidget(self.pushButton,0,1)

    self.main_widget = QWidget()
    self.main_widget.setLayout(self.layout)
    self.setCentralWidget(self.main_widget)

    self.pushButton.clicked.connect(self.addLineEdit)

def addLineEdit(self):

    newLineEdit = QLineEdit()
    self.layout.addWidget(newLineEdit,Form.x,0)
    Form.x += 1

if __name__ == "__main__":
   import sys
   app = QApplication(sys.argv)
   form = Form()
   form.show()
   sys.exit(app.exec_())
