I'm using PyQt5 designer to make a little application. I mostly work with designer rather than building from scratch so this might be a silly question. Basically i have a main menu and a "create" button that when clicked will open up the other pyqt5 .py file (also created in designer) i have been working on.
So far i complied the ui files into .py files and imported the popup window that i want to be able to generate more than one of and then i use this code to some success:
I have not added any additonal code to the converted ui files excpect this function:
Here is some code from my mainmenu and popoutwindow .py files:
this is the setupUi being called from my file im trying to replicate

This works great for opening up ONE extra window, which stays open while my main window is open which is what i want, but then when i go to click to make another window appear, it just replaces the one i already had up, so i can only seem to have one extra at a time.
I figure that my old window is being referenced by self.popWin , and then being replaced over and over so my question i guess is what is the best way to go about "generating" windows instead of just referencing the same window over and over.. i tried to remove the "self" part but then the window just dosent even appear when i go to create a new window so i am kind of lost
for example i would expect to be able to write something like this but im not really sure how to go about doing so
currentWindows = []
newPopWin = QtWidgets.QMainWindow()
newBookUI = BookPopout()
newBookUI.setupUi(newPopWin)
newPopWin.show()
currentWindows.append(newPopWin)
this would be ideal so i could keep track of all current open windows so i may terminate them all once i close my main menu.
Any help would be appreciated to put me on the right track, i have tried looking up solutions but lots of examples are not using code converted from a UI file.
The problem is simple, we are overwriting an attribute and at that moment the previous element is deleted, for that reason only a window. As you point out the solution is to store it in a list.
But before that, I recommend you not to write your logic in the .py generated by Qt Designer since for example let's say that you want to modify something of the design, then when generating the new .py it will erase all your logic. What PyQt recommends is to use create another file where you generate the logic adviritiendote with the message: # WARNING! All changes made in this file will be lost!. So restore the previous files I called bookPopup.py and mainmenu.py by removing the openNewBook. Following the docs recommendation we obtain the following:
main.py

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***

sys.exit()
def main():
import sys
app = QtWidgets.QApplication(sys.argv)
application = ApplicationWindow()
application.show()
sys.exit(app.exec_())

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.
Thank you so much :D
Try it:

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.
