Two ways on setting up Designer on Ubuntu 24.04 LTS

When it comes to installing the software "QtDesigner" as Python-Package you will almost read about installing "pyqt6-tools" without even mentioning a more simplistic way to avoid running into the danger of broken dependencies (caused by potentially different pyqt6 version requirements of your Python set-up). Also the version behind pyqt6-tools or the Ubuntu-Package will never exceed those from the Python-Package "qt6_applications", which are up-to-date and used by myself. Following steps are critical for my setup to work, either as Python- or as Ubuntu-Package:

Install QtDesigner 6.5.0 as Python-Package

Install two Python-Packages:

Terminal

pip3 install qt6_applications pyqt6     

Executable for Qt-Designer will be found at: $HOME/.local/lib/python3.10/site-packages/qt6_applications/Qt/bin/designer

To Convert ui-File to Py-File use following console-command:

Usage of PyUIC6 (Python-Package)

Terminal

python3 -m PyQt6.uic.pyuic [ui-File] -o [OUTPUT-File]

or similar synthax

python3 -m PyQt6.uic.pyuic -o [OUTPUT-File] [ui-File] 

Install QtDesigner 6.4.2 as Ubuntu-Package

Install pyqt6 as Python-packages first:

Terminal

pip3 install pyqt6      

Then install two Ubuntu-Packages:

Terminal

sudo apt install designer-qt6 pyqt6-dev-tools       (pyqt6-dev-tools for pyuic6)

Executable for Qt-Designer will be found at: /usr/lib/qt6/bin/designer

To Convert ui-File to Py-File use following console-command:

Usage of PyUIC6 (Ubuntu-Package)

Terminal

pyuic6 [ui-File] -o [OUTPUT-File] 

or similar synthax

pyuic6 -o [OUTPUT-File] [ui-File]
