How to open another window in and take user input in Pyqt5 Python

I am trying to create a GUI using pyqt5. I have one main window with pushbutton. When i click on pushbutton it should open another window which is having input form to take first name and last name. Below is my code. I am able to open another window but when i am submitting the details on opened window and clicking on Submit Details button, nothing is happening.
Please note, if i directly call Child_ui in Main_Ui then then I am able to see the output form PrintInput function but same is not happening when I converted ui files in class.
Main_ui.py:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(299, 148)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(90, 70, 75, 23))
self.pushButton.setObjectName("pushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "Register user"))
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_())
I have converted this Qt designed file to class file:
Main.py:
from PyQt5 import QtCore, QtGui, QtWidgets
from Main_ui import *
from Child import *
class Main(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super().__init__(parent)
self.setupUi(self)
self.pushButton.clicked.connect(self.openChild)
def openChild(self):
self.child = QtWidgets.QMainWindow()
self.ui = userRegistation()
self.ui.setupUi(self.child)
self.child.show()
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Main()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
Below is my Child_ui.py qt designer script:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_ChildWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(284, 141)

self.label.setGeometry(QtCore.QRect(20, 30, 71, 16))
self.label.setObjectName("label")
self.label_2 = QtWidgets.QLabel(self.centralwidget)
self.label_2.setGeometry(QtCore.QRect(20, 60, 71, 16))
self.label_2.setObjectName("label_2")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(20, 100, 251, 23))

.. yes it is working and i was also able to do it this way. I want to do it using two different file. Also I don't want to write logic in Qt designed file because if i do any change in Qt designer then whole script needs to change
Update

implementing buttons' functions on main instead on script from pyqt5

I created a GUI using Qt designer, and converted it into .py file.
I used to write the functions directly in the GUI .py file, but I've been told to separate the code into two files: one with only the GUI commands as been converted from Qt designer, and Main - that would work all of the buttons and widgets of the GUI.
Now, I've managed to import the GUI from different file, and when I run the script the GUI does come up, but when I try to write functions I seem to have troubles.
This is my main:
from PyQt5 import QtWidgets
from mainwin import Ui_MainWindow
import sys
class ApplicationWindow(QtWidgets.QMainWindow):
def __init__(self):
super(ApplicationWindow, self).__init__()
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.exitbtn.clicked.connect(self.exitclicked) ***this is the connection and function that I'm trying to make 'em work***
def exitclicked(self,Dialog):
sys.exit()
def main():
import sys
app = QtWidgets.QApplication(sys.argv)
application = ApplicationWindow()
application.show()
sys.exit(app.exec_())
if __name__ == "__main__":
main()
And I don't know if it's relevant, but this is my GUI converted from Qt designer.

Would love if someone can write the right syntax to be able to implement functions through main.

How do you want the QTreeView to show something if it does not tell you what to show?, a QTreeView what it does is show the content of some model, in your case you should use a QFileSystemModel.
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
...
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
model = QtWidgets.QFileSystemModel(self)
model.setRootPath(QtCore.QDir.rootPath())
self.treeView.setModel(model)
self.treeView.expandAll()
self.treeView.setRootIndex(model.index(QtCore.QDir.rootPath()))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())

Adding a simple clock to a GUI

I have some code for a very generic/blank GUI with some labels and pushbuttons and an LCD widget. I also have some code for a separate window which just uses an LCD widget to display the time. My question is how do I insert to code for the clock into the generic GUI code to make that LCD widget display the time?
from PyQt5.QtCore import QTime, QTimer
from PyQt5.QtWidgets import QApplication, QLCDNumber
class DigitalClock(QLCDNumber):
def __init__(self, parent=None):
super(DigitalClock, self).__init__(parent)
self.setSegmentStyle(QLCDNumber.Filled)
timer = QTimer(self)
timer.timeout.connect(self.showTime)
timer.start(1000)
self.showTime()
self.setWindowTitle("Digital Clock")
self.resize(150, 60)
def showTime(self):
time = QTime.currentTime()
text = time.toString('hh:mm')
if (time.second() % 2) == 0:
text = text[:2] + ' ' + text[3:]
self.display(text)
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
clock = DigitalClock()
clock.show()
sys.exit(app.exec_())
That's the code for the simple clock and I want to insert that into the following to make the LCD widget display the time like this one does:
from PyQt5 import QtCore, QtGui, QtWidgets

def setupUi(self, mainWindow):

self.DigitalClock.setGeometry(QtCore.QRect(110, 190, 64, 23))

Simple solution:
Assuming that the first file is called DigitalClock.py and the second main.py then it is only necessary to add the import to main.py and change the line that the QLCDNumber creates:
main.py
from DigitalClock import DigitalClock
# ...
self.DigitalClock = DigitalClock(self.centralwidget) # QtWidgets.QLCDNumber(self.centralwidget)
Long solution:
Promote the QLCDNumber to use the DigitalClock, you could take the guide of this other answer where you would exchange QVideoWidget with DigitalClock and PyQt5.QtMultimediaWidgets with DigitalClock.
The other way is to create a widget plugin so that it can be used directly in Qt Designer.

DigitalClockFile.py
from PyQt5.QtCore import QTime, QTimer
from PyQt5.QtWidgets import QApplication, QLCDNumber
class DigitalClock(QLCDNumber):
def __init__(self, parent=None):
super(DigitalClock, self).__init__(parent)
self.setSegmentStyle(QLCDNumber.Filled)
self.setDigitCount(10)
timer = QTimer(self)
timer.timeout.connect(self.showTime)
timer.start(1000)
self.showTime()
self.setWindowTitle("Digital Clock")
self.resize(150, 60)
def showTime(self):
time = QTime.currentTime()
text = time.toString('hh:mm:ss')
if (time.second() % 2) == 0:
text = text[:2] + ' ' + text[3:5]+' '+text[6:]
self.display(text)
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
clock = DigitalClock()
clock.show()
sys.exit(app.exec_())

Add all the three files in the single directory.Since you already implement DigitalClock dont add the clock in thi UI just inherit class generated by QtDEsigner and add your clock in the inherited transformedUI.py and simply running the main.py will achieve desired task.Hope it helps

PyQt5. Dialog window doesn't show up. Closes main window instead

I faced a problem while programming my gui appliacation in PyQt5. I'm trying to open my second (dialog) window by clicking on "addclientbutton". But instead it simply closes the main window. Here I created it:
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(281, 176)
self.comboBox = QtWidgets.QComboBox(Dialog)
self.comboBox.setGeometry(QtCore.QRect(90, 10, 71, 22))
self.comboBox.setObjectName("comboBox")
self.comboBox.addItem("")
self.comboBox_2 = QtWidgets.QComboBox(Dialog)
self.comboBox_2.setGeometry(QtCore.QRect(10, 10, 71, 22))
self.comboBox_2.setObjectName("comboBox_2")
self.comboBox_2.addItem("")
self.dateTimeEdit = QtWidgets.QDateTimeEdit(Dialog)
self.dateTimeEdit.setGeometry(QtCore.QRect(10, 60, 194, 22))
self.dateTimeEdit.setObjectName("dateTimeEdit")
self.label_2 = QtWidgets.QLabel(Dialog)
self.label_2.setGeometry(QtCore.QRect(10, 40, 91, 16))
self.label_2.setObjectName("label_2")
self.lineEdit = QtWidgets.QLineEdit(Dialog)
self.lineEdit.setGeometry(QtCore.QRect(150, 110, 113, 20))
self.lineEdit.setObjectName("lineEdit")
self.label_3 = QtWidgets.QLabel(Dialog)
self.label_3.setGeometry(QtCore.QRect(150, 90, 121, 16))
self.label_3.setObjectName("label_3")
self.lineEdit_2 = QtWidgets.QLineEdit(Dialog)
self.lineEdit_2.setGeometry(QtCore.QRect(10, 110, 113, 20))
self.lineEdit_2.setObjectName("lineEdit_2")
self.label_4 = QtWidgets.QLabel(Dialog)
self.label_4.setGeometry(QtCore.QRect(10, 90, 111, 16))
self.label_4.setObjectName("label_4")
self.pushButton = QtWidgets.QPushButton(Dialog)
self.pushButton.setGeometry(QtCore.QRect(150, 140, 111, 23))
self.pushButton.setObjectName("pushButton")
self.pushButton_2 = QtWidgets.QPushButton(Dialog)
self.pushButton_2.setGeometry(QtCore.QRect(10, 140, 111, 23))
self.pushButton_2.setObjectName("pushButton_2")
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
Here I created the button itself:
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(803, 803)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.calendarWidget = QtWidgets.QCalendarWidget(self.centralwidget)
self.calendarWidget.setGeometry(QtCore.QRect(0, 0, 331, 191))
self.calendarWidget.setObjectName("calendarWidget")
self.addclient = QtWidgets.QPushButton(self.centralwidget)
self.addclient.setGeometry(QtCore.QRect(0, 350, 331, 81))
font = QtGui.QFont()
font.setFamily("Verdana")
font.setPointSize(10)
self.addclient.setFont(font)
self.addclient.setObjectName("addclient")
Then I wrote this function:
import sys
from interface import *
from dialog import *
from PyQt5 import QtCore, QtGui, QtWidgets
class MyWin(QtWidgets.QMainWindow):
def __init__(self, parent=None):
QtWidgets.QWidget.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.ui.addclient.clicked.connect(self.addclientfunction)
def addclientfunction(self):
self.Ui_Dialog.Dialog.show()
if __name__=="__main__":
app = QtWidgets.QApplication(sys.argv)
myapp = MyWin()
myapp.show()
sys.exit(app.exec_())
So, here it is - sorry for this PyQt designer abuse :D

You just need to create a dialog class in the same way you did for the main window. So something like this should work:
class MyDialog(QtWidgets.QDialog):
def __init__(self, parent=None):
super(MyDialog, self).__init__(parent)
self.ui = Ui_Dialog()
self.ui.setupUi(self)
class MyWin(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MyWin, self).__init__(parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.ui.addclient.clicked.connect(self.addclientfunction)
def addclientfunction(self):
self.dialog = MyDialog()
self.dialog.show()
But please note that the Ui_Dialog and Ui_MainWindow classes shown in your question are incomplete. My answer assumes that your complete ui classes work as expected.
