In this video, Nicolas Fella shares practical tips for writing cleaner, safer, and more performant QML code using qmllint.
QML’s flexibility makes it powerful but it can also lead to code that works while being hard to read, fragile, or inefficient. Using a small example application, the video walks you through common QML anti-patterns and shows how QML lint helps catch them early.
By the end of the video, all QML lint warnings are resolved, resulting in clearer and more maintainable QML code.
The example code showcased in this video is available here: https://github.com/KDABLabs/kdabtv/tree/master/Qml-Tips-And-Tricks/qmllint
