Advanced Qt - A Deep Dive 5/6 - ModelView Part 1
summary
A concrete walkthrough shows replacing a widget-based thumbnail loader with a model adapter to avoid loading 5,000 images into X memory, using a custom adapter for an XML DB, a delegate that paints thumbnail cells, and built-in models like QFileSystemModel and QAbstractListModel. Code examples implement rowCount, data, setData, beginInsertRows/endInsertRows and emit dataChanged; proxy usage appears via QSortFilterProxyModel to sort/filter without touching source data.
