We should have installed first:

• GNAT Ada compiler version GPL 2021 or FSF 12.1
• Python version 3.7 or newer

We install PySide 6 the official Python bindings for Qt under a user Python environment:

% cd $HOME
% python3 -m venv env
% source env/bin/activate
% pip install pyside6
% deactivate

% cd $HOME
% git clone https://github.com/Blady-Com/QtAda6.git

It tests if PySide is correctly installed:

% cd $HOME
% cd QtAda6
% gprbuild -P qtada6_tests.gpr -XTarget_OS=OSX test_01
% PYTHONPATH=$HOME/env/lib/python3.9/site-packages:$PWD/tests bin/test_01

Note: this is the command line and the result on macOS, change Target_OS with yours (see $HOME/QtAda6/simple_components/lib_components.gpr for possible values) and change PYTHONPATH to yours.

We can tell where is a specific Python library location with the Load procedure: Py.Load ("Path/to/libpython");

It tests few QtCore API:

% cd $HOME
% cd QtAda6
% gprbuild -P qtada6_tests.gpr -XTarget_OS=OSX test_02
% PYTHONPATH=$HOME/env/lib/python3.9/site-packages bin/test_02
PySide version: 6.5.2
QtCore version: 6.5.2

This program also shows the way of programing with QtAda6:

1. initialize Python interpreter
2. take the global interpreter lock
3. initialize QtAda6
4. declare QTAda6 objects and initialize them
5. call QtAda6 API
6. finalize QtAda6 objects
7. finalize QtAda6
8. finalize Python interpreter

It tests few QtGui API:

% cd $HOME
% cd QtAda6
% gprbuild -P qtada6_tests.gpr -XTarget_OS=OSX test_03
% PYTHONPATH=$HOME/env/lib/python3.9/site-packages:$PWD/tests bin/test_03

A GUI app with a graphic clock is launched:

It tests few QtWidgets API:

% cd $HOME
% cd QtAda6
% gprbuild -P qtada6_tests.gpr -XTarget_OS=OSX test_04
% PYTHONPATH=$HOME/env/lib/python3.9/site-packages bin/test_04

A GUI app with widgets label and button is launched:

This is the very first release whose goal is mostly to get feedbacks on how it is usable or if the class hierarchy is as user friendly as C++ version.

Known limitations are :

• Only QtCore, QtGui and QtWidgets are provided
• Signal, composed types and so on are not or partially translated
• Class inheritance is not available on Ada side
• No memory management
