Visualizing Data with Rust and Qt

CXX-Qt is KDAB's extension to CXX, which adds Qt features like properties, signals and slots to CXX. In this step-by-step tutorial, we implement a QAbstractItemModel subclass, which is key to exposing structured data to QML.

At the end we'll have a small Todo app that drives the data entirely from Rust and doesn't even need any C++ code.
