The post walks through three concrete steps: introducing missing QAbstractItemModel subclasses (replacing QTableWidget/QComboBox direct data manipulation with a proper ItemTableModel), creating a domain object proxy (ItemProxy wrapping the Item domain object with bindable Q_PROPERTYs), and introducing a PageProxy that ties together ItemProxy and ItemTableModel while absorbing business logic previously scattered in the Window class. Each step is illustrated with real code commits from a sample Gilded Rose application, progressively emptying the Window class of business logic in preparation for the final Qt Quick UI migration. ## Full article daily.dev links to this article rather than hosting it.
