Qt designer window not showing

SandraB

HI. Have been playing around with PyQt5 tutorials. Discovered Qt Designer. Designed a basic layout, again following a tutorial. Cannot get it to show. Any pointers? What am I missing?

Thanks

Program:

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QDialog, QApplication, QWidget

class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.combox = QtWidgets.QComboBox(self.centralwidget)
self.combox.setGeometry(QtCore.QRect(40, 120, 111, 31))
font = QtGui.QFont()
font.setPointSize(10)
self.combox.setFont(font)
self.combox.setObjectName("combox")
self.combox.addItem("")
self.combox.addItem("")
self.comboy = QtWidgets.QComboBox(self.centralwidget)
self.comboy.setGeometry(QtCore.QRect(230, 120, 111, 31))
font = QtGui.QFont()
font.setPointSize(10)
self.comboy.setFont(font)
self.comboy.setObjectName("comboy")
self.comboy.addItem("")
self.comboy.addItem("")
self.Submit = QtWidgets.QPushButton(self.centralwidget)
self.Submit.setGeometry(QtCore.QRect(140, 410, 111, 31))
font = QtGui.QFont()
font.setPointSize(10)
self.Submit.setFont(font)
self.Submit.setObjectName("Submit")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(130, 250, 141, 61))
font = QtGui.QFont()
font.setPointSize(12)
self.label.setFont(font)
self.label.setObjectName("label")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)

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

    self.InitUI_MainWindow()

def retranslateUi(self, MainWindow):
    _translate = QtCore.QCoreApplication.translate
    MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
    self.combox.setItemText(0, _translate("MainWindow", "0"))
    self.combox.setItemText(1, _translate("MainWindow", "1"))
    self.comboy.setItemText(0, _translate("MainWindow", "0"))
    self.comboy.setItemText(1, _translate("MainWindow", "1"))
    self.Submit.setText(_translate("MainWindow", "Submit"))
    self.label.setText(_translate("MainWindow", "x xor y ="))

if name == "main":
import sys
app = QtWidgets.QApplication(sys.argv)
Ui_MainWindow = QtWidgets.QMainWindow
ui = Ui_MainWindow()
sys.exit(app.exec_())

Hi and welcome to devnet,

From a quick look you don't call the show method of your UI_MainWindow object anywhere, therefore nothing is shown.

Hi.

Denni O. I have picked up vaguely that Designer was going to be a pig to work with. I just found the learning process of PyQt fairly hard work, though maybe I just need to find the right tutorial.

SGaist. Thank you. Ok will have a look at this.
