Constructor & Destructor Documentation

ConstraintModel()

ConstraintModel::ConstraintModel ( QObject *  parent = nullptr )

explicit

Constructor.

Creates an empty ConstraintModel with parent parent

Definition at line 61 of file kdganttconstraintmodel.cpp.

~ConstraintModel()

ConstraintModel::~ConstraintModel ( )

override

Destroys this ConstraintModel.

Definition at line 77 of file kdganttconstraintmodel.cpp.

Member Function Documentation

addConstraint()

void ConstraintModel::addConstraint ( const Constraint &  c )

virtual

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

Subclassing ConstraintModel and overriding addConstraint() and removeConstraint() can provide re-entrancy issues in the ConstraintModel<->ConstraintProxy interaction. Therefore it is recommended to better subclass GraphicsView and override addConstraint() there.
