i cant provide a python sample code.
But basically a new window is shown for a widget without a parent or if it has a parent the widget's window flag property is set toQt::Window. -

@Samuel-Bachorik
connect()the first window's button clicked signal to a slot which callssecondWindow.show(). This is one of the most basic things you can do in a Qt UI.firstWindow.button.clicked.connect(secondWindow.show) -
This is how my first windows looks like is it possible to connect it by your way @JonB
And my second window looks same just changed few things.class MyWindow(QMainWindow):
counter = 0
score = 0
test = 0def __init__(self): self.question_prompts = [ ] self.score = 0 self.counter = 0 self.test = 0 super(MyWindow, self).__init__() self.setGeometry(200, 200, 500, 300) self.setWindowTitle("Samko") self.label = QtWidgets.QLabel(self) self.label.move(20, 30) self.label.setText("Login system") self.update() self.label1 = QtWidgets.QLabel(self) self.label1.move(151, 50) self.label1.setText("Do you have account\ny/n ?") self.update2() self.b1 = QtWidgets.QPushButton(self) self.b1.setText("Enter") self.b1.move(149, 120) self.b1.resize(100, 32) self.b1.clicked.connect(self.clicked) self.textbox = QLineEdit(self) self.textbox.move(150, 90) self.textbox.resize(170, 28) self.textboxValue = self.textbox.text() def update(self): self.label.adjustSize() def update2(self): self.label1.adjustSize()def window():
app = QApplication(sys.argv)
win = MyWindow()
win.show()
sys.exit(app.exec_())window()

@Samuel-Bachorik said in open new window in pyqt5:
self.b1.clicked.connect(self.clicked)That will make clicking the button connect to whatever the
MyWindow.clickedmethod does. Where is that in your code? The method needs to show secondWindow, or just make itself.b1.clicked.connect(secondWindow.show), as I said. -
You can try subprocess to open your secondfile.py at the same time from the first window. :)

class MainWindow(QWidget): def __init__(self, parent=None): super(MainWindow, self).__init__(parent) -
Hello guys.
I have another but so close question. The main problem is all this tactics is not working on qtdesigner based .py files.
For examples:
As you see there is just one buton. There is nothing more.
Just i wanted, when i push the button launch the same things.
This the first untouched code:

MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())I just copied the class
It's offer me build init
I aceepted
Finally any solution didn't help me. Especially designer based codes hasn't solution.
