Hey @tvcsop,

First, to upload the picture, you need to use this:

As for the application, I would assume you want to do this locally as DigitalOcean does not offer Windows 10 by default. Here is a step-by-step guide to doing so.

  1. Install PyQt5-tools: The PyQt5-tools package includes Qt Designer. It is not included in the base PyQt5 package. Here’s how to install it:

In your terminal (Command Prompt on Windows, Terminal on macOS/Linux), activate your virtual environment and run:

pip install pyqt5-tools
  1. Find where PyQt5-tools was installed: Python packages get installed in your Python site-packages directory. You can find this location by running:
python -c "import site; print(site.getsitepackages())"

This will output a list of paths. Look for the path that ends in “site-packages”.

  1. Locate Qt Designer: In the site-packages directory, find the pyqt5_tools directory. Inside this directory, you will find a “Qt/bin” directory. The Qt Designer executable is named designer.exe on Windows, and should be located in this “bin” directory.

  2. Launch Qt Designer: You can launch Qt Designer by double-clicking on the designer.exe file in File Explorer. If you want to launch it directly from the command line, navigate to the directory where the designer.exe file is located using the cd command, and then type ./designer.exe to run it.

cd <path-to-pyqt5_tools>/Qt/bin
./designer.exe

Replace <path-to-pyqt5_tools> with the path you found in step 2. If your path contains spaces, enclose it in quotes.

These steps assume that you’re using Windows, as indicated in your question. The exact details might be slightly different on other operating systems. If you’re having trouble, let me know!
