  • Which Python GUI to choose best for Camera control applications?

Dear Luxonis Forum,

I am wondering which python GUI to choose best to build up small camera control applications
That ideally can run into the While True: Loop.

  • Tkinter and PyQt5 seem to require threading and slow down the process of the cameras.

  • PySimpleGUI seems to be the best but is not possible for me because I need numba in one application and this only runs on python 3.9 and my tkinter needs to be updated for PySimpleGUI to work on a higher python version

I only need it to create buttons that for example change the focus of the camera 🙂
Thank you very much for your help.

    BonkoKaradjov I don't personally have any experience running the GUIs outside pyqt so here is a GPT response:

    1. wxPython
      • Pros:
      • Mature and stable cross-platform GUI framework.
      • Works well with Python 3.9.
      • Can run a main event loop and also be updated periodically from another part of the code using non-blocking calls.
      • Cons:
      • Like Tkinter and PyQt, it’s event-loop based. You’ll need to carefully integrate your camera loop, often by using a timer or invoking wx.CallLater/wx.CallAfter for periodic camera updates.

    2. DearPyGui
      • Pros:
      • Immediate-mode GUI (retained mode under the hood, but feels like immediate mode), which can simplify how you integrate it with continuous loops.
      • Has an event processing system that might be simpler to integrate with a while loop.
      • It’s GPU-accelerated and can be efficient.
      • Cons:
      • Somewhat newer and less traditional than Tkinter or wxPython, which may mean fewer examples or a slightly steeper learning curve.
      • Version Compatibility: Generally works on Python 3.9+ without major hurdles.

    3. Kivy
      • Pros:
      • Designed for interactive applications, can run on Python 3.9.
      • Supports an event-driven architecture but can be flexible with updates.
      • Cons:
      • Heavier than a simple GUI library if you only need a few buttons.
      • More learning overhead and can be considered overkill if your only goal is to display a few buttons.

    4. Simple Web Interface (Flask/Quart + Web Browser)
      • Pros:
      • Entirely sidesteps the Python GUI event loop problem by hosting a small web server in Python.
      • You control the camera loop in the main script, and issue camera commands by making HTTP requests from a browser-based interface.
      • Very minimal overhead on the camera side if done correctly.
      • Cons:
      • Requires running a local server and using a web browser for the GUI. Not truly a “desktop GUI” but very flexible and often simpler to integrate with continuous loops.

    If you have enough performance on the machine, I'd recommend WEBUI since it.is the simplest.

    Thanks,

      Thank you dear @jakaskerl I will have a look at those libraries.

      I know it seams pretty stupid to create a GUI for a sensor camera but my customers in the arts section want to control the system by themselves and need a solution that is plug and play and easy to control 😃

      Thank you again very much for your help.
