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

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))

Python PyQt5 threading don't work

i want to create a progress bar showing(as busy) until the code of a button ends .My target is to show it when button(connected to function) pressed ,stay visible as code runs , and hide it when the function connected to the button ends.This task is done partially but my progress bar setVisible(True) waits until code ends and they show.

MainWindow.show()
sys.exit(app.exec_())

In your case I see that you have created functions unnecessarily, I have eliminated some. According to what you tell me, it is not necessary for the signal to carry information, so I will create a signal without parameters. the slot connected to the button must make visible the QProgressBar and start the thread, and the signal job_done must connect with the method that hides the QProgressBar, in the following example use QThread::sleep() to emulate some processing.
class ProgressThread(QtCore.QThread):
job_done = QtCore.pyqtSignal()
def __init__(self, parent=None):
super(ProgressThread, self).__init__(parent)
def do_work(self):
QtCore.QThread.sleep(2) # emulate processing
self.job_done.emit()
def run(self):
self.do_work()
class mainProgram(QtWidgets.QMainWindow, Ui_MainWindow): # main window
def __init__(self, parent=None):
super(mainProgram, self).__init__(parent)
self.setupUi(self)
self.progress_thread = ProgressThread()
self.progress_thread.job_done.connect(self.on_job_done)
self.create_ui()
self.B_aerodrome_data.clicked.connect(self.aerodrome_data)
def aerodrome_data(self):
self.start_thread()
def start_thread(self):
self.progress.setVisible(True)
self.progress_thread.start()
def on_job_done(self):
print("Generated string : ")
self.progress.setVisible(False)
def create_ui(self):
[...]

try this code, you will find your solution from here.
when you will press the button thread will start and emit int data to the progress bar from 0-100

It is not advisable to modify the class that Qt Designer generates, and worse if you are a beginner. The most recommended is to create a class that implements logic and use the design already created.
To do this you must choose the appropriate Widget, if you used as a template to MainWindow you should use QMainWindow, if you use Widget you must use QWidget and if you use any of the variants of Dialog you should use QDialog as I think this is the case.
Since the task is simple it is not necessary to create a method like slot, we could use a lambda function: lambda: self.stackedWidget.setCurrentIndex(1)
All of the above I implemented in the following code:
class Dialog(QtWidgets.QDialog, Ui_form):
def __init__(self, parent=None):
QtWidgets.QDialog.__init__(self, parent)
self.setupUi(self)
self.stackedWidget.setCurrentIndex(0)
self.login_button.clicked.connect(self.Confirm_Button_Clicked)
self.register_button.clicked.connect(lambda: self.stackedWidget.setCurrentIndex(1))
self.cancel_button.clicked.connect(self.cancel_button_clicked)
def Confirm_Button_Clicked(self):
file = open('user.txt','r')
[...]
def cancel_button_clicked(self):
self.stackedWidget.setCurrentIndex(0)
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
w = Dialog()
w.show()
sys.exit(app.exec_())
Note: If you want to return to the first page you should place the value of 0 as the current index, remember that the indexes start from 0.

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.
