  Okay using the snippet you have given I believe this might help you with what you are trying to do. The part that comes before the saveData function is assumed to have been done somewhere else within your program but is essential for having the saveData function work properly. Now I used a QTreeView as opposed to a QTreeWidget but they are similar, however, you might have to tweak things a little if you need to use that QTreeWidget

  tableWdgt = QTreeView() model = QStandardItemModel(0, cols) tableWdgt.setModel(self.model) def saveData(self): filename = QFileDialog.getSaveFilename(self,'Save File',os.getenv('Home')) rows = self.tableWdgt.model.rowCount() cols = self.tableWdgt.model.columnCount() with open(filename[0],'w') as filOut: for row in range(rows): for col in range(cols): if col in (0, 3): #grabs 1st and 4th columns cellValue = self.tableWdgt.model.item(row, col).text() filOut.write(cellValue)

  @Luemmel well the QLabel class has a Qt.Format that allows you to set the format to RichText which supports HTML4 encoding perhaps that will work or something similar to it cannot really say their documentation is like searching for a needle in a haystack for these various fairly simple features -- like setting the formatting of a Header Label should be a simple property of a window but it is not. So good luck on this.

  @LarsR not sure if you are still looking but I have been using OpenCue located on https://github.com/vfxpipeline Now granted it is not pyqt5 but its close enough to use it has a tool to better understand how the MVC could be implemented within pyqt5

  smells like a pyqt installation problem. Did you install it from a prepared package, or build from source?

  python can convert string values to integers if the string represents a valid integer...such as

  s="123" iVal=int(s)

  If the thing cannot be converted then it throws an exception.

  So I solved my problem.
  It turns out QImage needs the image to be a flat numpy array.
  Here is how it's done:

  qrgb_dict = {'r': lambda x: QtGui.qRgb(x, 0, 0), 'g': lambda x: QtGui.qRgb(0, x, 0), 'b': lambda x: QtGui.qRgb(0, 0, x)} colortable = [qrgb_dict[color](i) for i in range(256)] img = QtGui.QImage(arr, w, h, w, QtGui.QImage.Format_Indexed8) img.setColorTable(colortable)

  Where arr is an array of shape (h,w) and with uint8 values in 0-255

  I was able to solve this by switching to pycharm, for some reason spyder did not want to cooperate, kept getting DLL not found errors, "application failed could not find or load qt plugin could not be initialized", and importing QCharts would not work. everything seems to be working now thorough pycharm.

  In short use Qt/C++ for Android.

  PyQt claims to support Android, but nobody achieved to get it working. Qt for Python doesn't support it at all.

  QPushButton is a subclass of QAbstractButton that adds animation when clicked. Subclass QAbstractButton and implement whatever functionality you need.

  I use asyncio, asyncqt and websockets to replace QWebsocket before Qt for python become more mature

  Edit : This seems like a known issue--Missing ssl support for QWebSocketServer and QWebSocket
  Edit : Check the source codes of PySide2, I am sure the websocket of Qt do not support ssl yet.

  So you're right, it does appear to be a logger issue rather than a Qt one. It wasn't crashing the program at any point, but rather complaining about object cleanup order. Because of the larger structure of our code files, I couldn't assign the logger to wholely be a child of the QMainWindow, but putting the following code in the quit procedure did silence the messages.

  import logging logging.raiseExceptions = False

  Thanks for your contributions.

  Sorry, I figured it just failed on the last item in the list above. In any case, I just downloaded the offline version of the installer and it worked fine. This gives me a short cut to Qt Designer so I don't need the kit for Python.

  You should use the default threading available as a standard python library for your threads. Its called "threading", just "threading". It's very, very simple.

  OK, so the issue turned out to be something different. We are using QtPy and it needs the environment variable QT_API set to pyside2 for our Windows setup. For some reason the environment passed to QProcess isn't inheriting that variable and it was defaulting to pyside. Setting it manually to pyside2 by calling setProcessEnvironment on our QProcess before the start call gets everything working.

  Not sure if this is a PySide2 bug or not. The QProcess.execute documentation says:
  "The environment and working directory are inherited from the calling process."
  but it doesn't say this explicitly for start.
