Debugging Performance Issues With Qt-based UI Applications

A look at a smart washing machine UI application and how to improve performance.


Interactive user interfaces (UI) are fast becoming a basic requirement in many embedded applications and Qt is a popular cross-platform application and framework to help develop such compelling UIs. As with any software application, embedded UI development also requires numerous debugging iterations to achieve the level of desired performance (e.g. non-laggy response etc.) This whitepaper walks through a real-world flow of debugging performance issues on a Qt-based ‘smart washing machine’ UI application.
