Qt Model/View Architecture

Architecture Overview

Data Source ──→ Model ──→ [Proxy Model] ──→ View ──→ Delegate (renders cells)
                 ↕                            ↕
              QAbstractItemModel         QAbstractItemView

Separate data (model) from presentation (view). The delegate handles painting and editing per-cell. Proxy models layer transformations (sort, filter) without modifying the source model.
