I created a Windows .exe file from a python script using PyInstaller but when I launch the executable I get the error: AttributeError: 'ApplicationLogin' object has no attribute 'img_location'. However, running the same script from the terminal it works without issues.
Below is the piece of the code where the error is detected. The python version I used is 3.9.10

self.icons_location=parametri['icons']

I tried to look on the web for similar issue but I didn't find any hint

I got an error message when trying to run the above code:
ModuleNotFoundError: No module named 'PySide6.__feature__'
If I break the first line into
import PySide6
from __feature__ import snake_case, true_property
the code could run but PyCharm complains that
Unresolved reference: __feature__
How could I fix it?
Thanks for your help.
QClipboard::dataChanged() was not emitted in QtWebEngine context with pyqt6 or pyside6, but it works fine with qt5/pyqt5, how to solve it ?

I find the solution here
The sandbox somehow blocks the WM_CLIPBOARDUPDATE message (
https://learn.microsoft.com/en-us/windows/win32/dataxchg/wm-clipboardupdate
) and QPA can't notify about clipboard changes.
The sandbox on windows is enabled since
https://codereview.qt-project.org/c/qt/qtwebengine/+/276060
neosettler, as a workaround you can disable the sandbox by the
--no-sandbox command line argument or by setting the QTWEBENGINE_DISABLE_SANDBOX environment variable.
Then I changed my code to:

from PyQt6.QtCore import pyqtSlot as Slot
from PyQt6.QtCore import pyqtSignal as Signal

self.clipboard = QGuiApplication.clipboard()
self.clipboard.dataChanged.connect(self.clipboardTextChanged)
#Slot()

I am currently trying to create a GUI that allows users to type in whatever words they want to be translated into R2-D2's voice.
I have used Qt 5 Designer to create a user input using Line Edit and a button that will publish the user input to a specified topic in ROS. I have also converted it into a python file using pyuic5 -o as r2d2_sound_control.py and I have a main file called main_r2d2_sound_control.py that I will run to initialise the GUI.
How do you store and parse a string from Line Edit using python? I do not know how to declare the string from the user input and parse it when the button is clicked. I'm using pyqt 4
Thank you in advance.

I tried to establish a network connection with PySide (Ubuntu 15.04, Python3.4, PySide 1.2.4). I used the example code from the documentation.
The QNetworkAccessManager does not send the request and I recieve no answer. I checked the Network state with QNetworkSession(QNetworkConfigurationManager().defaultConfiguration()).State() but it says the State is invalid. This seems to make no sense since I am on a desktop pc with a network connection via ethernet cable.
My complete example for the test is the following code:
#!/usr/bin/python3
# -*- coding: utf-8 -*-
import sys
from PySide.QtGui import QApplication
from PySide.QtCore import QUrl
from PySide.QtNetwork import QNetworkAccessManager, QNetworkRequest, QNetworkSession, QNetworkConfigurationManager
def replyFinished(reply):
print(reply)
if __name__ == "__main__":
app = QApplication(sys.argv)
manager = QNetworkAccessManager()
manager.finished.connect(replyFinished)
print(QNetworkSession(QNetworkConfigurationManager().defaultConfiguration()).State())
print("Sending request")
print(manager.get(QNetworkRequest(QUrl("http://www.heise.de/ct/"))))
This prints
PySide.QtNetwork.QNetworkSession.State.Invalid
Sending request
<PySide.QtNetwork.QNetworkReply object at 0x7f4b59c9af08>
but it should display the PySide.QtNetwork.QNetworkReply object twice.
My example was too small. I realized this because of the comment of Pavel Strakhov. I extended it to display a window with a button. By clicking the button it connects successfully. QNetworkSession(QNetworkConfigurationManager().defaultConfiguration()).State() is still invalid but it works.
This is the working code:
#!/usr/bin/python3
# -*- coding: utf-8 -*-
import sys
from PySide.QtGui import QApplication, QWidget, QBoxLayout, QPushButton
from PySide.QtCore import QUrl
from PySide.QtNetwork import QNetworkAccessManager, QNetworkRequest, QNetworkSession, QNetworkConfigurationManager
class Window(QWidget):
def __init__(self):
super().__init__()
self.manager = QNetworkAccessManager()
self.manager.finished.connect(self.reply_finished)
layout = QBoxLayout(QBoxLayout.TopToBottom)
button = QPushButton("connect")
button.clicked.connect(self.network_connect)
layout.addWidget(button)
self.setLayout(layout)
self.setWindowTitle("Network test")
self.setGeometry(100, 100, 200, 150)
self.show()
def network_connect(self):
print(QNetworkSession(QNetworkConfigurationManager().defaultConfiguration()).State())
request = QNetworkRequest(QUrl("http://example.org"))
print("Sending request")
self.manager.get(request)
def reply_finished(self, reply):
print(reply)
print(reply.readData(500))

I started a project in Qt Creator initially with a C++ backend, but then switched it to use PyQt5. I have a main.qml, where when I press a button called Exit, I call Qt.quit().
However, I get a General Message stating: Signal QQmlEngine::quit() emitted, but no receivers connected to handle it.
My question is, how do I receive this signal and handle it?
Code:
main.py:
import sys
import PyQt5
from PyQt5 import QtCore
from PyQt5 import QtGui
from PyQt5 import QtQml
from PyQt5.QtCore import QObject pyqtSignal
class DestinyManager,(QtGui.QGuiApplication):
"""the app self"""
def __init__(self, argv):
super(DestinyManager, self).__init__(argv)
# Define a new signal called 'trigger' that has no arguments.
trigger = pyqtSignal()
def connect_and_emit_trigger(self):
# Connect the trigger signal to a slot.
self.trigger.connect(self.handle_trigger)
self.menuItem_Exit.clicked.connect(self.close)
# Emit the signal.
self.trigger.emit()
def handle_trigger(self):
# Show that the slot has been called.
print("trigger signal received")
def main(argv):
app = DestinyManager(sys.argv)
engine = QtQml.QQmlEngine(app)
component = QtQml.QQmlComponent(engine)
component.loadUrl(QtCore.QUrl("exit.qml"))
topLevel = component.create()
if topLevel is not None:
topLevel.show()
else:
for err in component.errors():
print(err.toString())
app.exec()
if __name__ == '__main__':
QObject,main(sys.argv)
Exit.qml:
import QtQuick 2.4
import QtQuick.Controls 1.3
import QtQuick.Window 2.2
Window {
Button {
id: btn_Exit
text: "Exit"
onClicked: Qt.quit();
}
}
There are a few syntax errors in the python script, but ignoring those, the code can be made to work like this:
def main(argv):
app = DestinyManager(sys.argv)
engine = QtQml.QQmlEngine(app)
engine.quit.connect(app.quit)
...
Which is to say, you simply need to connect the qml quit signal to an appropriate slot in your python script.
