如何在pyqt中的单个窗口中打开多个页面？

Question

I created two windows

First window

 from PyQt5 import QtCore, QtGui, QtWidgets from dial import Ui_dial from chat import Ui_Chat class Ui_Form(object): def setupUi(self, Form): Form.setObjectName("Form") Form.resize(764, 719) font = QtGui.QFont() font.setKerning(False) Form.setFont(font) Form.setStyleSheet() self.call_button = QtWidgets.QPushButton(Form) self.call_button.setGeometry(QtCore.QRect(320, 500, 111, 71)) font = QtGui.QFont() font.setFamily("Times New Roman") font.setPointSize(10) font.setBold(True) font.setWeight(75) self.call_button.setFont(font) self.call_button.setStyleSheet("") self.call_button.setText("") icon2 = QtGui.QIcon() icon2.addPixmap(QtGui.QPixmap(":/images/Images/call.png"), QtGui.QIcon.Normal, QtGui.QIcon.Off) self.call_button.setIcon(icon2) self.call_button.setIconSize(QtCore.QSize(58, 58)) self.call_button.setCheckable(True) self.call_button.setAutoExclusive(True) self.call_button.setObjectName("call_button") self.call_button.setShortcut(QtGui.QKeySequence(QtCore.Qt.Key_Space)) self.call_button.clicked.connect(self.dialwindow) self.ilabel = QtWidgets.QLabel(Form) self.ilabel.setGeometry(QtCore.QRect(210, 60, 331, 191)) font = QtGui.QFont() font.setFamily("Sylfaen") font.setPointSize(18) self.ilabel.setFont(font) self.ilabel.setStyleSheet("background-image: url(:/images/Images/label_back1.jpg);") self.ilabel.setObjectName("ilabel") self.retranslateUi(Form) QtCore.QMetaObject.connectSlotsByName(Form) def retranslateUi(self, Form): _translate = QtCore.QCoreApplication.translate Form.setWindowTitle(_translate("Form", "Form")) import icons_rc if __name__ == "__main__": import sys app = QtWidgets.QApplication(sys.argv) Form = QtWidgets.QDialog() ui = Ui_Form() ui.setupUi(Form) Form.show() sys.exit(app.exec_()) 

Second Window

 from PyQt5 import QtCore, QtGui, QtWidgets import dial_rc class Ui_dial(object): def setupUi(self, dial): dial.setObjectName("dial") dial.resize(739, 712) dial.setStyleSheet() self.dialpage_label = QtWidgets.QLabel(dial) self.dialpage_label.setGeometry(QtCore.QRect(240, 120, 301, 511)) self.dialpage_label.setObjectName("dialpage_label") self.callend_button = QtWidgets.QPushButton(dial) self.callend_button.setGeometry(QtCore.QRect(340, 520, 91, 71)) self.callend_button.setText("") icon = QtGui.QIcon() icon.addPixmap(QtGui.QPixmap(":/images/Images/end.png"), QtGui.QIcon.Normal, QtGui.QIcon.Off) self.callend_button.setIcon(icon) self.callend_button.setIconSize(QtCore.QSize(45, 45)) self.callend_button.setObjectName("callend_button") self.callend_button.clicked.connect(self.endcall) def retranslateUi(self, dial): _translate = QtCore.QCoreApplication.translate dial.setWindowTitle(_translate("dial", "Dialog")) if __name__ == "__main__": import sys app = QtWidgets.QApplication(sys.argv) dial = QtWidgets.QDialog() ui = Ui_dial() ui.setupUi(dial) dial.show() sys.exit(app.exec_()) 

How to show this different windows in single window?when click on button new window is open ,so i want show when i click on the button that second window open in same screen.so i need expertise on this problem

Answer 1

First modify your python script so that the class inherits from QtWidgets.QMainWindow by

class Ui_Form(QtWidgets.Qdialog):

Then write an init function so that your class can be instantiated, ie an object can be created. Once that is done, you can chuck out the QtWidgets.QDialog() object, the one that goes by the name dial in your script, being passed to your setupUI(). Then replace this object being passed with self.

Overall your code will look like this.

class Ui_dial(QtWidgets.Qdialog):

def __init__(self):
    super().__init__()//inheriting from the object.
def setupUi(self, dial):
    self.setObjectName("dial")
    self.resize(739, 712)
    self.setStyleSheet()
    self.dialpage_label = QtWidgets.QLabel(dial)
    self.dialpage_label.setGeometry(QtCore.QRect(240, 120, 301, 511))
    self.dialpage_label.setObjectName("dialpage_label")
    self.callend_button = QtWidgets.QPushButton(dial)
    self.callend_button.setGeometry(QtCore.QRect(340, 520, 91, 71))
    self.callend_button.setText("")
    icon = QtGui.QIcon()
    icon.addPixmap(QtGui.QPixmap(":/images/Images/end.png"),
def retranslateUi(self):
    _translate = QtCore.QCoreApplication.translate
    self.setWindowTitle(_translate("dial", "Dialog"))

Do the same for your other script and then make objects of these classes and call them as,

First_window = Ui_Form()
First_window.show()
Second_window = Ui_dial()
Second_window.show()

You might need to use resize() to adjust the two windows and to accommodate them according to your needs.
