Detailed Description

A class used to represent a dependency.

Instances of this class represent a dependency between the data items pointed to by a start-QModelIndex and an end-QModelIndex.

Constructor & Destructor Documentation

Constraint::Constraint	(	const QModelIndex &	idx1,
		const QModelIndex &	idx2,
		Type	type = TypeSoft
	)

Constructor. Creates a dependency for idx2 on idx1.

Parameters

type	controls if the constraint is a soft one that is allowed to be broken (ie, go backwards in time) or a hard constraint that will not allow the user to move an item so that the constraint would have to go backwards. The default is TypeSoft.

Actually enforcing hard constraints is the responsibility of the AbstractGrid subclass used in the view.
