窗口小部件在PopUp窗口上没有响应

标签： python python-3.x pyqt pyqt5

我已经使用Qt Designer设计了2 ui，并将它们导入到我用作主程序的新.py文件中。一个是主窗口，另一个是自定义弹出对话框。我能够毫无困难地运行MainWindow。我也可以运行Popup (QDialog, Modal)但是一旦显示，小部件就不会响应

很抱歉这个问题，但在线上看之后，我无法让它工作，最大的问题是编译器没有向我显示任何错误。代码运行没有麻烦，但小部件不会更新/响应

如果代码有点乱，我很抱歉，我上个月学习了Python，上周学了PyQT。

以下是该计划的代码：

import sys
import _pickle as cPickle
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QWidget, QAction, QTabWidget,QVBoxLayout
from PyQt5 import QtCore, QtGui, QtWidgets
from PedidoUI import Ui_MainWindow
from Emergente1 import Ui_Dialog


#I define a PopUp Dialog

        Ui_Dialog.__init__(self)
        self.setupUi(Dialog)
        self.botonAceptar.clicked.connect(self.AgregarItems)


#It should add the string "Prueba" as an Item to the list.
    def AgregarItems(self):
        self.listWidget.addItem("Prueba")


#This is the Main Class     
class ProgramaPedido(Ui_MainWindow):

        self.setupUi(MainWindow)

        self.ui.setupUi(self.Dialog)

以下是PopUp对话框的代码：

from PyQt5 import QtCore, QtGui, QtWidgets

    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(356, 277)
        self.listWidget = QtWidgets.QListWidget(Dialog)
        self.listWidget.setGeometry(QtCore.QRect(40, 10, 256, 192))
        self.listWidget.setObjectName("listWidget")
        self.botonAceptar = QtWidgets.QPushButton(Dialog)
        self.botonAceptar.setGeometry(QtCore.QRect(270, 250, 75, 23))
        self.botonAceptar.setObjectName("botonAceptar")
        self.botonAgr = QtWidgets.QPushButton(Dialog)
        self.botonAgr.setGeometry(QtCore.QRect(40, 210, 75, 23))
        self.botonAgr.setObjectName("botonAgr")
        self.lineEdit = QtWidgets.QLineEdit(Dialog)
        self.lineEdit.setGeometry(QtCore.QRect(120, 210, 113, 20))
        self.lineEdit.setObjectName("lineEdit")
        self.botonBor = QtWidgets.QPushButton(Dialog)
        self.botonBor.setGeometry(QtCore.QRect(40, 240, 75, 23))
        self.botonBor.setObjectName("botonBor")

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

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
        self.botonAceptar.setText(_translate("Dialog", "Aceptar"))
        self.botonAgr.setText(_translate("Dialog", "Agregar"))
        self.botonBor.setText(_translate("Dialog", "Borrar"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    Dialog = QtWidgets.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(Dialog)
    Dialog.show()
    sys.exit(app.exec_())

问题是您正在创建不同类的对象。 Qt Designer只提供一个填充窗口小部件的类，因此它不是窗口小部件，所以正确的方法是创建一个继承相应窗口小部件并使用该设计的类，通常该类应具有以下结构：

class Your_Widget(Widget_Class, Design_Class):
    def __init__(self,*args, **kwargs):
        Widget_Class.__init__(self, *args, **kwargs)
        self.setupUi(self)

然后我们以下列方式使用它：

#I define a PopUp Dialog
class PopUp(QDialog, Ui_Dialog):
    def __init__(self,*args, **kwargs):
        QDialog.__init__(self, *args, **kwargs)
        self.setupUi(self)
        self.botonAceptar.clicked.connect(self.AgregarItems)

    #It should add the string "Prueba" as an Item to the list.
    def AgregarItems(self):
        self.listWidget.addItem("Prueba")


#This is the Main Class     
class ProgramaPedido(QMainWindow, Ui_MainWindow): 
    def __init__(self,*args, **kwargs):
        QMainWindow.__init__(self, *args, **kwargs)
        self.setupUi(self)

        self.Dialog = PopUp()
        self.toolButton.clicked.connect(self.open_dialog)

    #I call the PopUp   
    def open_dialog(self):
        self.Dialog.exec_()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    prog = ProgramaPedido()
    prog.show()
    sys.exit(app.exec_())
