		const QModelIndex &	index
	)		const

		const QModelIndex &	index
	)		const

Propagates changed data from the editor to the model.

 {
     if (!index.isValid())

void SessionModelDelegate::updateEditorGeometry	(	QWidget *	editor,
		const QStyleOptionViewItem &	option,

Makes an editor occupying whole available space in a cell.

If cell contains an icon as a decoration (i.e. icon of material property), it will be hidden as soon as editor up and running.
