  @Kent-Dorfman I totally missed the concept that QImage references the buffer, not copies it. I included it in my dictionary and now it works. Thank you.

  Just a guess, instead of subclassing QThread, perhaps it would work better with the moveToThread method.

  Better use Anaconda and install PySide2 with conda.

  my approach to this very issue will be to create a python class that holds the binary data (as arrays) that makes up the icons, then feed that data to QPixmap, and then to QIcon instances.

  I'm not aware of any tool to do that. UI is an XML description of the interface. PY is the processed output of that description. I'm not sure anyone has ever identified enough need to go the other direction.

  Here is a basic example...
  When using QT, temp = None.
  When the same script is run using Selenium, temp = 5.

  import sys import time from PySide2 import QtCore, QtGui, QtWidgets from PySide2 import QtWebEngineWidgets from PySide2.QtWebEngineWidgets import QWebEngineView app = QtWidgets.QApplication(sys.argv) view = QtWebEngineWidgets.QWebEngineView() view.setUrl(QtCore.QUrl("https://google.com")) view.show() temp = view.page().runJavaScript('return 1+4') print(temp) import sys import time from selenium import webdriver browser_options = webdriver.FirefoxOptions() browser_options.add_argument('-headless') browser = webdriver.Firefox(firefox_options=browser_options) browser.get('https://google.com') temp = browser.execute_script('return 1+4') print(temp) browser.close() browser.quit()

  there are two ways to use forms:

  The first way is to run the setupUi() method on a target widget. The other way is to subclass the Ui_xxxx class itself. You're probably seeing examples of the second method where the subclass has its own init() method.

  Superb @Erudite-Monkey,
  This is what i was looking for

  I am working in a 3d package Maya
  the reference code i created was

  from PySide2 import QtWidgets from PySide2 import QtGui from PySide2 import QtCore test_lay = QtWidgets.QVBoxLayout() test_lay_wid = QtWidgets.QWidget() test_parentwid = QtWidgets.QWidget() test_button = QtWidgets.QPushButton() test_listwid = QtWidgets.QListWidget(test_parentwid) #QtWidgets.QListWidgetItem(testing_print.out_var, test_listwid) QtWidgets.QListWidgetItem("Test_01", test_listwid) QtWidgets.QListWidgetItem("Test_02", test_listwid) QtWidgets.QListWidgetItem("Test_03", test_listwid) test_lay.addWidget(test_parentwid) test_lay.addWidget(test_button) test_lay_wid.setLayout(test_lay) test_listwid.insertItem(10, QtWidgets.QListWidgetItem("Test_04")) test_lay_wid.show() def print_someting(): print str(test_listwid.currentItem().text()), "apna time aayega" #test_listwid.currentItem().text() test_listwid.itemClicked.connect(print_someting)

  which i figured out yesterday night :)
  I rarely have used lambda but with your eg i'll even learn something better

  when i select an item(key) from the listwidget it should display data(value) stored in it in texteditwid without any looping -- checked want to use only dict to display data on widget as per model/view want to know its possible, if yes will appreciate examples -- checked

  You nailed it man

  didn't even require the last point

  this query relates partially to the first one, if the dict option isn't handy enough kindly suggest provide an example of loop with itemselected signal because whenever i try i prompts Qt native signal

  Thank You, @Erudite-Monkey

  I found out the error and I feel so stupid. I used the same name (ui) for two variables in

  ClassifyPage = QWidget() ui = ClassifyPageUIClass() ui.setupUi(ClassifyPage)

  and

  MainWindow = QMainWindow() ui = MainWindowUIClass() ui.setupUi(MainWindow)

  so the the slots connects of my QTabWidget were overwrighted.

  Use

  data = TableData() table.setModel(data)

  where data derives from QAbstractTableModel e.g.

  class TableData(QAbstractTableModel): def __init__(self, parent: QObject = None): super().__init__(parent) # The number of rows to display def rowCount(self, parent: QModelIndex = QModelIndex()): return 3 # The number of columns to display def columnCount(self, parent: QModelIndex = QModelIndex()): return 3 # Return the data you want to display in the table (could be stored e.g. in a list of tuples) def data(self, index: QModelIndex, role: int = Qt.DisplayRole) -> object: if role == Qt.DisplayRole: return index.row() * 10 + index.column() return None

  @priscilla-v You need to find the folder with PyQt application, then find the file with main application (you_qt_app.py), In this file find the class which realizes the application window and usually in the init function of this class add something like this:

  self.setWindowIcon(QtGui.QIcon("Path/To/logo.png"))

  or if

  window = QtGui.QWidget() window.setWindowIcon(QtGui.QIcon("Path/To/logo.png"))

  with buttons, labels, other elements, they are usually in the init function of the application/widget class

  self.some_button.setIcon(QtGui.QIcon("Path/To/logo.png"))

  or

  some_button.setIcon(QtGui.QIcon("Path/To/logo.png"))

  the names of the buttons (any elements) can be any.
  Usually, buttons have a declaration:

  self.some_but = QtGui.PushButton()

  but it will not necessarily be like this.
  Need to read by the content in the app files.
  The images is recommended to place in the one folder with app. For example, if app path App/app.py can create in the App folder Icons folder and put to Icons folder logo.png file.
  The path will be:

  self.setWindowIcon(QtGui.QIcon("Icons/logo.png"))

  You can put here some part of the file with the application if You have a problems with code.
