Programming with Qt Quick 4/6 - Visual Elements Part 2
summary
Covers building UIs with Qt Quick models and views: uses list model and XML list model with JavaScript API (append, insert, get) to supply named properties for delegates, and visual item model to supply ready-made QML items. Shows list view, grid view and path view behavior, header/footer/highlight components, image scaling to 64x64 with smooth and preserveAspectFit, and that list view reuses only visible delegates while repeater instantiates all items; cacheSize is tunable for smoother scrolling. Notes shadowing limitation for model properties and some version-specific attached-property bugs.
