如何使用 pyqt5 和 ZE85823B4E7DB1064F4301E1C7497819 从主对话框 window 打开第二个 window

Question

HI I am trying to develop a plugin. I have used PyQt5 designed to create the Gui.I want to know how to launch a new window after I click on a button.

This is the interface I have created using PyQt5 Designer. Here is the Image link

Once the Activate button is clicked, Activation key sent dialog box opens as shown in the above image. Once the OK button is clicked, i need to open a new window as shown

Here is main ui_dialog.py

from .gisedify_support_dialog_login import Ui_Dialog
FORM_CLASS, _ = uic.loadUiType(os.path.join(
os.path.dirname(__file__), 'gisedify_support_dialog_base.ui'))
class GisedifySupportDialog(QtWidgets.QDialog, FORM_CLASS):
  def __init__(self, parent=None):
    """Constructor."""
    super(GisedifySupportDialog, self).__init__(parent)
    # Set up the user interface from Designer through FORM_CLASS.
    # After self.setupUi() you can access any designer object by doing
    # self.<objectname>, and you can use autoconnect slots - see
    # http://qt-project.org/doc/qt-4.8/designer-using-a-ui-file.html
    # #widgets-and-dialogs-with-auto-connect
    self.setupUi(self)

def open_login_dialog(self):
    self.nd = Login_Dialog(self)
    self.nd.show()

class Login_Dialog(QtWidgets.QDialog,Ui_Dialog):
 def __init__(self, parent=None):
    super(Login_Dialog, self).__init__(parent)

This is my UI_Dialog class

from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Dialog(object):
def setupUi(self, Dialog):
    Dialog.setObjectName("Dialog")
    Dialog.resize(400, 300)
    ....
    ....
    self.pushButton.setObjectName("pushButton")


def retranslateUi(self, Dialog):
    _translate = QtCore.QCoreApplication.translate
    Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
    self.label.setText(_translate("Dialog", "Enter activation key"))
    self.pushButton.setText(_translate("Dialog", "Login"))

I am calling the loginwindow using

GisedifySupportDialog().open_login_dialog()

The above code does nothing and no error also. Please help me in opening login window when OK button is clicked from main window

Try this:

def open_login_dialog(self):
    Dialog = QtWidgets.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(Dialog)
    Dialog.exec_()
