Detailed Description

The ConstraintModel keeps track of the interdependencies between gantt items in a View.

Constructor & Destructor Documentation

ConstraintModel::ConstraintModel ( QObject parent = 0)
explicit

Constructor. Creates an empty ConstraintModel with parent parent

ConstraintModel::~ConstraintModel ( )
virtual

Destroys this ConstraintModel

Member Function Documentation

void ConstraintModel::addConstraint ( const Constraint c)
virtual

Subclassing ConstraintModel and overriding addConstraint() and removeConstraint() can provide re-entrancy issues in the ConstraintModel<->ConstraintProxy interaction.

Therefore it is recommed to better subclass GraphicsView and override addConstraint() there.

Adds the constraint c to this ConstraintModel If the Constraint c is already in this ConstraintModel, nothing happens.

void ConstraintModel::cleanup ( )

bool ConstraintModel::removeConstraint ( const Constraint c)
virtual

Removes the Constraint c from this ConstraintModel. If c was found and removed, the signal constraintRemoved(const Constraint&) is emitted.

Returns
If c was found and removed, it returns true, otherwise it returns false.
