◆ interactionStateFor()

ItemDelegate::InteractionState ItemDelegate::interactionStateFor	(	const QPointF &	pos,
		const StyleOptionGanttItem &	opt,
		const QModelIndex &	idx
	)		const

virtual

Returns: The interaction state for position pos on item idx when rendered with options opt. This is used to tell the view about how the item should react to mouse click/drag.

Override to implement new items or interactions.

◆ itemBoundingSpan()

Span ItemDelegate::itemBoundingSpan	(	const StyleOptionGanttItem &	opt,
		const QModelIndex &	idx
	)		const

virtual

Returns: The bounding Span for the item identified by idx when rendered with options opt. This is often the same as the span given by the AbstractGrid for idx, but it might be larger in case there are additional texts or decorations on the item.

Override this to implement new itemtypes or to change the look of the existing ones.
