self.pushButton_3.clicked.connect(self.generate()) at this line you are not connecting the generate function but you are calling it by adding () to function name, so change it to self.pushButton_3.clicked.connect(self.generate) and self.generate should accept one argument x which is callback event of pushbutton
so either change definition of self.generate which accepts one argument
or make a lambda function which accepts one argument and calls self.generate by placing this line self.pushButton_3.clicked.connect(lambda x: self.generate())
I have created a manual web socket and I stucked.
Query) How to print continous/real time data receiving from server on text browser in pyqt5 GUI if connect (here name close) pushbutton is pressed (connection created) and if pushbutton is pressed again it should get toggled i.e. it should stop receiving data (connection close).
My code is
from PyQt5 import QtCore, QtGui, QtWidgets
from websocket import create_connection
class Ui_MainWindow(object):
def connect(self,MainWindow):
ws = create_connection("ws://192.168.0.205/ws")
self.textBrowser_2.append("Connection created")
while 1:
self.textBrowser_2.append(ws.recv())
print(ws.recv())

First of all, do not modify the code generated by QtDesigner so to apply my solution you must regenerate the .py file and call it gui.py: pyuic5 filename.ui -o gui.py -x.
On the other hand, do not use the websocket module since it is designed for synchronous logic, in this case it is better to use the QtWebSockets module that allows you to interact with the websockets using the Qt eventloop.
import sys
from PyQt5 import QtCore, QtWidgets, QtWebSockets
from gui import Ui_MainWindow
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super().__init__(parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.socket = QtWebSockets.QWebSocket()
self.socket.textMessageReceived.connect(self.handle_text_message_received)
self.ui.pushButton.clicked.connect(self.connect_to_websocket)
def connect_to_websocket(self):
if self.socket.state() == QtNetwork.QAbstractSocket.UnconnectedState:
url = "ws://192.168.0.205/ws"
self.socket.open(QtCore.QUrl(url))

The issue is that the when the button is pressed, the program crashes, telling me that "Event loop already running". How do I fix this?
Qt, like many GUI frameworks, is based on an event loop which is started with app.exec_() and then waits for events to react to (both from the user or the system).
For each Qt program there should always be a single and only QApplication instance running its event loop.
With your implementation, each time you press the button, you're trying to create and launch a new QApplication, and Qt will not allow you for the reason above.
Nonetheless, the problem with your code is somewhere else, as you are using the generated UI code in the wrong way: those files should never be used as a basis to create your program code (in fact, you should always leave them as they are).
I suggest you to carefully read the official documentation about using Designer to understand how to use those files.
Regenerate the UI files with pyuic, and then create a new script that will probably contain something similar to this:
from PyQt5 import QtWidgets
from ui_mainwindow import Ui_MainWindow
from ui_dialog import Ui_Dialog
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
super().__init__()
self.setupUi(self)
self.pushButton_2.clicked.connect(self.add)
def add(self):
dialog = Dialog(self)
dialog.exec_()
class Dialog(QtWidgets.QDialog, Ui_Dialog):
def __init__(self, parent=None):
super().__init__(parent)
self.setupUi(self)
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
mainWindow = MainWindow()
mainWindow.show()
sys.exit(app.exec_())
In this example I used the third method (multiple inheritance approach) explained in the documentation given above.
This is something I'm doing for work, to speed up a process with the software we use. I'm trying to change a text file by using different regex search & replace functions. I have that working, and I have the GUI the way I want it.

I just need to be able to pull the results from the input that has been entered, if the frames are enabled(checked) when I click the submit buttons. Output should be true or false for checkboxes and radio buttons and integers, a double, and a string for the rest. I'm sure I'm missing something simple.
We created a class MainWindow for the top-level window.
Create an instance of it and display the widget on the screen.
w = MainWindow()
w.show()
Added the ability to get the selected item in the QComboBox drop-down list.
Corrected the output format in the on_clicked method.

I am designing a GUI to capture an image from picamera, I am using PyQt5 to develop the GUI. I used camera.start_preview() function to see the live preview. After that I used a button named "Take" to capture the image and after capturing the image I showed the image in Qlabel by using self.label_2.setPixmap(QtGui.QPixmap()) command till this my code is working fine. Now I want to set the live preview of PiCamera into the same Qlabel, which I am using to show the captured image. Is it possible to set the live preview inside a QLabel?
After googling I found PIL can be used to stream live preview inside an window, but I have no idea how to implement it.
