@QueTeeHelper Exactly right, those are the comments I would have typed if it were my code :)

@kshegunov said in Odd issue, thread worker & timmer not running properly: Does the timer start at all? Does the thread start at all? the timer.start() gets called. But after that silence... Maybe everything gets deleted somewhere?

It depends on how you create your project/file. If you create a project of the type Application "Qt for Python", you will end up with a main.py where PySide2 is imported and I could not find the template file in the Qt installation files. If you simply create a new file of the type Python | Python Class you will be offered to choose between PyQt5 and Pyside2. The template file is in your Qt installation folder: Qt\Tools\QtCreator\share\qtcreator\templates\wizards\classes\python. Sorry, QtCreator is great but not perfect for Python yet from what I can tell :-/

Hi, You have both Qt's OpenGL module and Qt3D at your disposal for that.

Well thanks you

The linting is performed by pylsp, documentation for this can be found here: https://github.com/python-lsp/python-lsp-server There is not a great deal of configuration for this in QtCreator however if you create: ~/.config/pycodestyle You can add something like this to ignore specific rules: [pycodestyle] ignore = E226, E722, W504, E501 Also if you are interested in what pylsp is doing you can modify its command line to generate logs: [image: pylsp_config.png]

@Samuel-Bachorik I tried it, but I have the same problem, ehwn I try to execute the .exe file a message box open saying "Failed to execute script"

Hi, Your application does not run a web server therefore trying to access it with a web browser won't work. You will have to have a X11 server running on your Windows machine. See this article for an explanation about that.

Hi, You have here an example of how to build an area series. It's in C++ but easily translated to Python. I think it should provide you with the information you are looking for.

@Qt-Bot05 Well, it seems to me you're using Y values the wrong way round for upperSeries and lowerSeries! But I think the docs imply that doesn't actually matter, though you might want to verify by swapping. Also, you're testing with just 2 points, it's an area series so why would you test with less than 4? What are you expecting to see? Anyway, your issue is probably something else. Have you checked it works for you for other than QAreaSeries?

Did you ever find a fix? Mine is doing the exact same thing.

@Haujet-Zhao I don't know whether it's "supposed" to work in PySide. PyQt5 is more robust/has more support for other libraries. Have a read anyway of the (only) reply to https://stackoverflow.com/questions/63502837/pyqt5-app-using-timer-to-run-a-function-with-a-loop-makes-it-freeze-up, as possible way forward for PySide2/6?

@anoop1 As I said, how do you expect Python's Cmd.cmdloop to interact with Qt's event-driven system and windows/widgets?

@JKSH Thanks !!!

@Black-Cat You gorgot to connect the clicked signal from the new button...

@jsulm Thanks i will try to use tour method @JonB i try this, it works Thanks a lot @JonB Now i will do what @jsulm propose i will work withe the qsql

@SGaist I assume this is learning exercise! :) He references a learning course he is doing.

Hi and welcome to devnet, You should add a setter to your widget to pass it the coordinates you want. On a side note, you should call update and not try to call the paintEvent method directly. Depending on your end goal, you might want to consider the Graphics View framework.
