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

super().__init__(parent)
self.ui = Ui_MainWindow()

self.socket = QtWebSockets.QWebSocket()

self.ui.pushButton.clicked.connect(self.connect_to_websocket)

This is a GUI where I plot data from serial communication.
I want to add an AutoPan for my GUI but I don't know how.
I read there is an autopan in Viewbox but don't know how to implement it.
The option of Autopan is available when I launch the gui buy right clicking on the gui and selectign it manually but I want it to be enabled by default .

The problem is, when I provide a link in the plainTextEdit box and press the pushButton, the application crashes. There must be some problem in on_search_clicked() as it is the only method I wrote and the rest is auto generated.

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.
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.

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)
