Automatize code in QTDesigner for objects

Automatize code in QTDesigner for objects - python

I would like to take names and values from 2 list to my QTDesigner text labels and QLineEdit, this is the code which I get:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(1249, 740)
self.label = QtWidgets.QLabel(Dialog)
self.label.setGeometry(QtCore.QRect(370, 180, 68, 19))
self.label.setObjectName("label")
self.label_2 = QtWidgets.QLabel(Dialog)
self.label_2.setGeometry(QtCore.QRect(370, 230, 68, 19))
self.label_2.setObjectName("label_2")
self.label_3 = QtWidgets.QLabel(Dialog)
self.label_3.setGeometry(QtCore.QRect(370, 280, 68, 19))
self.label_3.setObjectName("label_3")
self.lineEdit = QtWidgets.QLineEdit(Dialog)
self.lineEdit.setGeometry(QtCore.QRect(450, 180, 113, 25))
self.lineEdit.setObjectName("lineEdit")
self.lineEdit_2 = QtWidgets.QLineEdit(Dialog)
self.lineEdit_2.setGeometry(QtCore.QRect(450, 230, 113, 25))
self.lineEdit_2.setObjectName("lineEdit_2")
self.lineEdit_3 = QtWidgets.QLineEdit(Dialog)
self.lineEdit_3.setGeometry(QtCore.QRect(450, 280, 113, 25))
self.lineEdit_3.setObjectName("lineEdit_3")
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
def retranslateUi(self, Dialog):
_translate = QtCore.QCoreApplication.translate
Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
self.label.setText(_translate("Dialog", "a"))
self.label_2.setText(_translate("Dialog", "b"))
self.label_3.setText(_translate("Dialog", "c"))
self.lineEdit.setText(_translate("Dialog", "1"))
self.lineEdit_2.setText(_translate("Dialog", "2"))
self.lineEdit_3.setText(_translate("Dialog", "3"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
Dialog = QtWidgets.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.show()
sys.exit(app.exec_())
And when I have two list of names and I would like to generate automatically those fields, eg.
from PyQt5 import QtCore, QtGui, QtWidgets
list_names = ['a', 'b', 'c']
list_val = [1, 2, 3]
place = [350,400,450]
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(1249, 740)
for i in range(0,len(list_names)):
self.list_names[i] = QtWidgets.QLabel(Dialog)
self.list_names[i].setGeometry(QtCore.QRect(place[i], 110, 68, 19))
self.list_names[i].setObjectName(list_names[i])
self.list_val[i] = QtWidgets.QLineEdit(Dialog)
self.list_val[i].setGeometry(QtCore.QRect(place[i], 110, 113, 25))
self.list_val[i].setObjectName(list_val[i])
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
def retranslateUi(self, Dialog):
_translate = QtCore.QCoreApplication.translate
Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
for i in range(0, len(list_names)):
self.list_names[i].setText(_translate("Dialog", str(list_names[i])))
self.list_val[i].setText(_translate("Dialog", str(list_val[i])))
...
This is an example for only 3 factors in list, I have around 20 of them and I wondering if I can do it in a loop to create the output like that:

self.label_2.setText(_translate("Dialog", "file"))
self.pushButton.setText(_translate("Dialog", "select"))
self.pushButton_2.setText(_translate("Dialog", "push"))
These two classes have different window sizes and many different things.
How can I switch between two windows based on the login button of Ui_Dialog?
I know how to trigger on the login button but I don't know how to switch to another class.
I want to move to individual dialogs rather than being done in one dialog.

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.

The error that I get when I try to run it is:

Would love if someone can write the right syntax to be able to implement functions through main.
Thank you so much :D

Use setPlainText:
def click(self):
inputtext = self.lineEdit.text()
self.textEdit.setPlainText(inputtext)
Also you need to put function click inside class Ui_MainWindow, like this:
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
#your code
def click(self):
inputtext = self.lineEdit.text()
self.textEdit.setPlainText(inputtext)
Also call function click like:
self.pushButton.clicked.connect(self.click)

How to emit a signal from the pyqt5 groupbox that can be updated dynamically

I have the parallel thread that read 10 uart and prints the data in pyqt5 gui. But the issue I am facing is those groupbox get updated when all 10 jobs completed but not instantly.
EDIT: To achieve parallelism I am using joblib not pyqt thread.
What I want to achieve is change the state of groubox attributes such as a label, pushbutton text, and colour but I don't find a good example how to trigger a signal emit for the groupbox.
Do I need to emit the individual label, buttons in the groubox or I can emit as one groupbox object?
This is a minimalistic code, where it has just two groupbx. Can someone help how to emit the signal from groubox and catch that change, i.e the state of label, button text, and colour in the below code?
Below example update the groubox without any issue but in real each g1 method is uart and it's blocking call. I wait till all jobs to complete to see the changes on my GUI.

First of all I recommend you read Using the Generated Code from the docs. PyQt in this post recommends not modifying the code generated by Qt Designer since it is not a widget it is only a class that is used to fill a widget, instead it is better to create another class based on the chosen form and implement the logic there, since for example your code has a serious error: the signals can only be created in a QObject like the widgets but Ui_MainWindow is not.
Considering the above, the solution is:
from PyQt5 import QtCore, QtGui, QtWidgets
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.groupBox = QtWidgets.QGroupBox(self.centralwidget)
self.groupBox.setGeometry(QtCore.QRect(100, 140, 120, 141))
self.groupBox.setObjectName("groupBox")
self.pushButton_2 = QtWidgets.QPushButton(self.groupBox)
self.pushButton_2.setGeometry(QtCore.QRect(0, 40, 113, 32))
self.pushButton_2.setObjectName("pushButton_2")
self.pushButton_3 = QtWidgets.QPushButton(self.groupBox)
self.pushButton_3.setGeometry(QtCore.QRect(0, 90, 113, 32))
self.pushButton_3.setObjectName("pushButton_3")
self.label = QtWidgets.QLabel(self.groupBox)
self.label.setGeometry(QtCore.QRect(0, 20, 121, 16))
self.label.setObjectName("label")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(180, 80, 113, 32))
self.pushButton.setObjectName("pushButton")
self.groupBox_2 = QtWidgets.QGroupBox(self.centralwidget)
self.groupBox_2.setGeometry(QtCore.QRect(230, 140, 120, 141))
self.groupBox_2.setObjectName("groupBox_2")
self.pushButton_4 = QtWidgets.QPushButton(self.groupBox_2)
self.pushButton_4.setGeometry(QtCore.QRect(0, 40, 113, 32))
self.pushButton_4.setObjectName("pushButton_4")
self.pushButton_5 = QtWidgets.QPushButton(self.groupBox_2)
self.pushButton_5.setGeometry(QtCore.QRect(0, 90, 113, 32))

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
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.Clock = QtWidgets.QWidget(self.centralwidget)
self.Clock.setGeometry(QtCore.QRect(60, 420, 120, 80))
self.Clock.setObjectName("Clock")
self.DigitalClock = QtWidgets.QLCDNumber(self.centralwidget)
self.DigitalClock.setGeometry(QtCore.QRect(110, 190, 64, 23))
self.DigitalClock.setDigitCount(8)
self.DigitalClock.setObjectName("DigitalClock")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(100, 60, 75, 23))
self.pushButton.setObjectName("pushButton")
self.pushButton_2 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_2.setGeometry(QtCore.QRect(100, 110, 75, 23))
self.pushButton_2.setObjectName("pushButton_2")
self.pushButton_3 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_3.setGeometry(QtCore.QRect(100, 150, 75, 23))
self.pushButton_3.setObjectName("pushButton_3")
self.pushButton_4 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_4.setGeometry(QtCore.QRect(230, 60, 75, 23))
self.pushButton_4.setObjectName("pushButton_4")
self.pushButton_5 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_5.setGeometry(QtCore.QRect(220, 100, 75, 23))
self.pushButton_5.setObjectName("pushButton_5")
self.pushButton_6 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_6.setGeometry(QtCore.QRect(230, 150, 75, 23))
self.pushButton_6.setObjectName("pushButton_6")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(20, 60, 47, 13))
self.label.setObjectName("label")
self.label_2 = QtWidgets.QLabel(self.centralwidget)
self.label_2.setGeometry(QtCore.QRect(20, 120, 47, 13))
self.label_2.setObjectName("label_2")
self.label_3 = QtWidgets.QLabel(self.centralwidget)
self.label_3.setGeometry(QtCore.QRect(20, 160, 47, 13))
self.label_3.setObjectName("label_3")
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)
def retranslateUi(self, mainWindow):
_translate = QtCore.QCoreApplication.translate
mainWindow.setWindowTitle(_translate("mainWindow", "Sim Monitor"))
self.pushButton.setText(_translate("mainWindow", "PushButton"))
self.pushButton_2.setText(_translate("mainWindow", "PushButton"))
self.pushButton_3.setText(_translate("mainWindow", "PushButton"))
self.pushButton_4.setText(_translate("mainWindow", "PushButton"))
self.pushButton_5.setText(_translate("mainWindow", "PushButton"))
self.pushButton_6.setText(_translate("mainWindow", "PushButton"))
self.label.setText(_translate("mainWindow", "TextLabel"))
self.label_2.setText(_translate("mainWindow", "TextLabel"))
self.label_3.setText(_translate("mainWindow", "TextLabel"))
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_())

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
