Detailed Description

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

Definition at line 28 of file kganttconstraintmodel.h.

Constructor & Destructor Documentation

ConstraintModel::ConstraintModel ( QObject parent = nullptr)
explicit

Constructor. Creates an empty ConstraintModel with parent parent

Definition at line 51 of file kganttconstraintmodel.cpp.

ConstraintModel::~ConstraintModel ( )
override

Destroys this ConstraintModel

Definition at line 65 of file kganttconstraintmodel.cpp.

Member Function Documentation

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.

Definition at line 90 of file kganttconstraintmodel.cpp.

void ConstraintModel::cleanup ( )

Not used

Definition at line 142 of file kganttconstraintmodel.cpp.

void ConstraintModel::clear ( )

Removes all Constraints from this model The signal constraintRemoved(const Constraint&) is emitted for every Constraint that is removed.

Definition at line 134 of file kganttconstraintmodel.cpp.

QList< Constraint > ConstraintModel::constraints ( ) const
Returns
A list of all Constraints in this ConstraintModel.

Definition at line 154 of file kganttconstraintmodel.cpp.

QList< Constraint > ConstraintModel::constraintsForIndex ( const QModelIndex idx) const
Returns
A list of all Constraints in this ConstraintModel that have an endpoint at idx.

Definition at line 160 of file kganttconstraintmodel.cpp.

bool ConstraintModel::hasConstraint ( const Constraint c) const

Returns true if a Constraint with start s and end e exists, otherwise false.

Definition at line 183 of file kganttconstraintmodel.cpp.

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.
