I am trying to load the homescreen after the splashscreen

I am trying to load my homescreen after the splashscreen. Upon running the code, the splashscreen manages to load but it stops there. How do I fix this?
This is my SplashScreen class
class SplashScreen(QWidget):
def __init__(self):
super().__init__()
self.setFixedSize(700, 350)
self.setWindowFlag(Qt.FramelessWindowHint)
self.setAttribute(Qt.WA_TranslucentBackground)
self.counter = 0
self.n = 100
self.initUI()
self.timer = QTimer()
self.timer.timeout.connect(self.loading)
self.timer.start(30)
def initUI(self):
# layout to display splash scrren frame
layout = QVBoxLayout()
self.setLayout(layout)
# splash screen frame
self.frame = QFrame()
layout.addWidget(self.frame)
# splash screen title
self.title_label = QLabel(self.frame)
self.title_label.setObjectName('title_label')
self.title_label.resize(690, 120)
self.title_label.move(0, 5) # x, y
self.title_label.setText('Splash Screen')
self.title_label.setAlignment(Qt.AlignCenter)
# splash screen title description
self.description_label = QLabel(self.frame)
self.description_label.resize(690, 40)
self.description_label.move(0, self.title_label.height())
self.description_label.setObjectName('desc_label')
self.description_label.setText('<b>Splash Screen PyQt-5</b>')
self.description_label.setAlignment(Qt.AlignCenter)
# splash screen pogressbar
self.progressBar = QProgressBar(self.frame)
self.progressBar.resize(self.width() - 200 - 10, 50)
self.progressBar.move(100, 180) # self.description_label.y()+130
self.progressBar.setAlignment(Qt.AlignCenter)
self.progressBar.setFormat('%p%')
self.progressBar.setTextVisible(True)
self.progressBar.setRange(0, self.n)
self.progressBar.setValue(20)
# spash screen loading label
self.loading_label = QLabel(self.frame)
self.loading_label.resize(self.width() - 10, 50)
self.loading_label.move(0, self.progressBar.y() + 70)
self.loading_label.setObjectName('loading_label')
self.loading_label.setAlignment(Qt.AlignCenter)
self.loading_label.setText('Loading...')
This is the function that lets the splashscreen load and launch the WindowApp class but it does not work. What I mean by does not work I meant that it does not load the WindowApp. It just closes.
def loading(self):
# set progressbar value
self.progressBar.setValue(self.counter)
# stop progress if counter
# is greater than n and
# display main window app
if self.counter >= self.n:
self.timer.stop()
self.close()

I have tried changing this to WindowApp() just to check if the MainWindow has any problems but it manages to load without the splashscreen.
app = QApplication(sys.argv)
splash = SplashScreen()
splash.show()
sys.exit(app.exec_())

Check my answer from this previous post that I think will help you.
You can show the splash screen and when the splash screen closes then you can show your main window. It's similar to the login window from this previous question
But if you want to keep implementing your code the way you have it I think I know the problem.
You call a method which creates the QMainWindow and calls the .show() for that QMainWindow. Once the method is done the variables in that method are garbage collected and so is your QMainWindow object. The way to keep the reference and prevent those variables from getting garbage collected is by making it a class variable by adding self. in front of the variable.
I would maybe restructure a bit and do something like this:
if __name__ == "__main__":
app = QApplication(sys.argv)
splash = SplashScreen()
splash_closed = splash.exec_()
if splash_closed:
window = WindowApp()
window.show()
sys.exit(app.exec_())
Where the splashscreen is now a QDialog and when you're done loading you close the dialog with self.accept() instead of trying to show a new window:
class SplashScreen(QDialog):
def __init__(self):
super().__init__()
self.setFixedSize(700, 350)
self.setWindowFlag(Qt.FramelessWindowHint)
self.setAttribute(Qt.WA_TranslucentBackground)
self.counter = 0
self.n = 100
self.initUI()
self.timer = QTimer()
self.timer.timeout.connect(self.loading)
self.timer.start(30)
def initUI(self):
...
def loading(self):
# set progressbar value
self.progressBar.setValue(self.counter)
# stop progress if counter
# is greater than n and
# display main window app
if self.counter >= self.n:
self.timer.stop()
self.accept()
self.counter += 1
And you should also use the __init__ method on your main window and maybe move all the self.setupUI code in there, or just do something like this:
class WindowApp(QMainWindow):
def __init__(self):
QtWidgets.QDialog.__init__(self)
self.setupUi(self)
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(1006, 654)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")

Hope this helps

Trouble adding click event to PyQt5 button, no connect after clicked [duplicate]

This question already has answers here:
Calling a function upon button press
(3 answers)
Closed 3 years ago.
fairly new to PyQt and Python in general. I am having trouble applying a click event to a button in PyQt5. I am trying to add functionality to all the buttons I have, although it seems I am missing some initial setup to allow it to work. Looking through the documentation...
pushButton.clicked.connect("Do some action")
..should enable the click functionality on the targeted button.
I do not currently have the connect option available after the pushbutton.connect call.
I assume I am missing some setup in the class.

Thank you in advance for any help, I hope I have been clear enough.

I think it may be because your input is incorrect, an example piece:
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot
class App(QWidget):
def __init__(self):
super().__init__()
self.title = 'PyQt5 button - pythonspot.com'
self.left = 10
self.top = 10
self.width = 320
self.height = 200
self.initUI()
def initUI(self):
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
button = QPushButton('PyQt5 button', self)
button.setToolTip('This is an example button')
button.move(100,70)
button.clicked.connect(self.on_click)
self.show()
#pyqtSlot()
def on_click(self):
print('PyQt5 button click')
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
Here a function self.on_click is passed. In your example, you pass print('I am working'), which returns a None. You could fix this for instance like this:
from PyQt5 import QtCore, QtGui, QtWidgets
import cheekycheeky
import datetime
import ntplib
import time
class ContLCDClock(QtWidgets.QWidget,):
def __init__(self, parent = None):
QtWidgets.QWidget.__init__(self, parent)
self.ui = Ui_Form()
self.ui.setupUi(self)
self.timer = QtCore.QTimer()
self.timer.timeout.connect(self.updateLCD1)
self.timer.start(1000)
# self.timer2 = QtCore.QTimer()
# self.timer2.timeout.connect(self.updateLCD2)
# self.timer2.start(4000)
# self.time_format = "%H:%M:%S"
# self.client = ntplib.NTPClient()
# self.response = self.client.request('pool.ntp.org')
# self.clock = time.strftime(self.time_format, time.localtime(self.response.tx_time))
def updateLCD1(self):
self.currentTime = QtCore.QTime.currentTime()
self.strCurrentTime = self.currentTime.toString('hh:mm:ss')
self.ui.lcdNumber.display(self.strCurrentTime)
# def updateLCD2(self):
# self.time_format = "%H:%M:%S"
# self.client = ntplib.NTPClient()
# self.response = self.client.request('pool.ntp.org')
# self.clock = time.strftime(self.time_format, time.localtime(self.response.tx_time))
# self.ui.lcdNumber_2.display(self.clock)

how to detect a key release in pyqt

I want to create a PyQt5 window (Windows OS) which recognizes a button click with holding CTRL button. I successfully created a handler which recognizes CTRL key press but it couldn't find the pressing and releasing of a button which i need to call and dismiss button click event. I did a lot of search but the resources for PyQt5 seems pretty low. Any help is appreciated :)

I recommend you not to modify the code generated by Qt Designer, instead create a class that inherits the appropriate widget and use that class as an interface as I recommend PyQt. Going to the problem, you have to use the keyReleaseEvent method to listen when a key is released:

The code is executed but not displayed in Dialog, only the labels but not the progress bar.
Why does this happen?

The problem is that you are using the format function badly, this is used when you have a string and you want to insert data with a certain format.
The setProperty function requires as first parameter the property you want to assign, and a second value of the type that requires the property, in your case value requires an integer value so you can pass the percentage directly without needing to change it to string.
If you read many files this can block the main thread where the GUI is drawn, to solve this you must use QApplication.processEvents()
def showinform(self):
current_time = datetime.datetime.today().strftime("%Y-%b-%dT%H_%M")
alle = glob.glob('*.txt')
counterfile = noreports
porcentotal = 0
suma = 100/counterfile
counterbien = 0
for file in alle:
porcentotal += float(suma)
avance = round(float(porcentotal), 0)
self.dialogo.progressBar.setProperty("value", avance)
self.dialogo.textEdit.append("{}{}".format(file, avance))
print ('{!r} %'.format(avance))
dict = '{!r} %'.format(avance)
QApplication.processEvents()
f = open(file,'w')
f.write('result = ' + repr(dict) + '\n')
Note: I have changed the setText function to append in QTextEdit so that it is added and not overwritten.
Instead of using setProperty you could use the setValue function of QProgressBar:
self.dialogo.progressBar.setValue(avance)
Another recommendation is to verify that the counterfile is non-zero since it could generate an exception for the division.
