18 * \brief Proxy model that supports summary gantt items.
19 *
20 * This proxy model provides the functionality of summary items.
21 * A summary item is an item with type KGantt::TypeSummary and
22 * zero or more children in the model that it summarizes.
23 * GraphicsView itself does not dictate any policy for summary items,
24 * instead the logic for making the summary items start and end points
25 * span it's children is provided by this proxy.
26 *
27 * The start and end times of a summary is the min/max of the
28 * start/end times of it's children.
29 *
30 * \see GraphicsView::setModel
