QSkinny
The (Q)Skinny library is a framework built on top of the Qt scene graph and very few core classes from Qt/Quick. It offers a set of lightweight controls, that can be used from C++ and/or QML.
Doing the implementation in C++ allows to make use of the "scene graph" classes. Building controls from scene graph nodes allows for a lighter implementation than found with stacking "heavier" objects like QObject or QQuickItem. Offering a full featured C++ API allows the application code to benefit from following the same strategies.
Being "skinny" also means a design that separates concerns between the API and logic of the controls themselves, the styling of these controls, and the delegated rendering of the controls to the screen.
The code already provides a solid fundament for an automotive GUI with currently ~300K lines of pure C++ code. As expected it results in a good startup performance and a low memory footprint.
Nontheless QSkinny is lacking in areas like documentation or appealing default skins. The QML API has not been completed after reaching a proof of concept state. Furthermore the current selection of the implemented controls is limited to the needs of the driving projects.
QSkinny is supposed to run on all platforms being supported by Qt/Quick. But so far only Linux is actively tested. It might support all versions Qt >= 5.15, but you can rely on:
- Qt 5.15
- current long term supported ( LTS ) version of Qt ( at the moment Qt 6.5.x )
- current version of Qt
On debian bullseye these packages need to be installed for Qt5: build-essential cmake qtbase5-dev qtbase5-private-dev qtdeclarative5-dev qtdeclarative5-private-dev libqt5svg5-dev.
For Qt6 you need the corresponding packages.
Optional: When enabling the
hunspellfeature the following package needs to be installed:libhunspell-dev
Optional: When enabling the
pinyinfeature the following package needs to be installed:libimepinyin-dev
