Welcome to Qt Dev Helper’s documentation!

Qt Dev Helper

Toolbox to help develop Qt applications, improving the usability of the existing tooling.

Installation

pip install qt-dev-helper

OR

conda install -c conda-forge qt-dev-helper

Features

Usable as Library and/or CLI tool
Compatible with PEP517 build system (see test case)
CLI auto completion
Project wide configuration in pyproject.toml
Recursive asset compiler for Qt projects (using uic and rcc):
- *.ui -> *.py
- *.qrc -> *.py
- *.ui -> *.h
- *.qrc -> *.h
- *.scss -> *.qss
Support for multiple Qt tooling suppliers
- PySide6-Essentials
- qt6-applications
- qt5-applications
Ability to open all files in a folder in QtDesigner

Planned features

Stand alone executable for each release (Windows)
File watch mode
qss injection into *.ui files
pre-commit hooks

FAQ

Q: Why is PyQt5 not supported?

A: PyQt5 only ships a python specific version of uic and rcc breaking the tool API and compatibility with cpp projects. Use the matching version of qt5-applications as Qt tooling supplier.

Top-level package for Qt Dev Helper.

Contributing

Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given.

You can contribute in many ways:

Types of Contributions

Report Bugs

Report bugs at https://github.com/s-weigand/qt-dev-helper/issues.

If you are reporting a bug, please include:

Your operating system name and version.
Any details about your local setup that might be helpful in troubleshooting.
Detailed steps to reproduce the bug.

Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with “bug” and “help wanted” is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with “enhancement” and “help wanted” is open to whoever wants to implement it.

Write Documentation

Qt Dev Helper could always use more documentation, whether as part of the official Qt Dev Helper docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/s-weigand/qt-dev-helper/issues.

If you are proposing a feature:

Explain in detail how it would work.
Keep the scope as narrow as possible, to make it easier to implement.
Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

Ready to contribute? Here’s how to set up qt_dev_helper for local development.

Fork the qt-dev-helper repo on GitHub.

Clone your fork locally:

$ git clone git@github.com:your_name_here/qt_dev_helper.git

Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:
```
$ mkvirtualenv qt_dev_helper
$ cd qt-dev-helper/
$ pip install -e .
```

install the pre-commit and pre-push hooks:

$ pre-commit install && pre-commit install -t pre-push

Create a branch for local development:
```
$ git checkout -b name-of-your-bugfix-or-feature
```
Now you can make your changes locally.
When you’re done making changes, check that your changes pass flake8 and the tests, including testing other Python versions with tox:
```
$ tox
```
To get flake8 and tox, just pip install them into your virtualenv.

Commit your changes and push your branch to GitHub:

$ git add .
$ git commit -m "Your detailed description of your changes."
$ git push origin name-of-your-bugfix-or-feature

Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

The pull request should include tests.
If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.md.
The pull request should work for Python 3.8, 3.9 and 3.10. Check https://github.com/s-weigand/qt-dev-helper/actions and make sure that the tests pass for all supported Python versions.

Tips

To run a subset of tests:

$ pytest tests.test_qt_dev_helper

Deploying

A reminder for the maintainers on how to deploy. Make sure all your changes are committed (including an entry in HISTORY.rst). Then run:

$ bump2version patch # possible: major / minor / patch
$ git push --follow-tags

Travis will then deploy to PyPI if tests pass.
