Detailed Description

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

Constructor & Destructor Documentation

ConstraintModel()

ConstraintModel::ConstraintModel ( QObject * parent = nullptr )

explicit

Constructor. Creates an empty ConstraintModel with parent parent

Definition at line 50 of file kganttconstraintmodel.cpp.

~ConstraintModel()

ConstraintModel::~ConstraintModel ( )

override

Destroys this ConstraintModel

Definition at line 64 of file kganttconstraintmodel.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.

Definition at line 89 of file kganttconstraintmodel.cpp.

cleanup()

void ConstraintModel::cleanup

(

)

Not used

Definition at line 141 of file kganttconstraintmodel.cpp.

clear()

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 133 of file kganttconstraintmodel.cpp.

constraints()

QList< Constraint > ConstraintModel::constraints

(

)

const

Returns

A list of all Constraints in this ConstraintModel.

Definition at line 153 of file kganttconstraintmodel.cpp.

constraintsForIndex()

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 159 of file kganttconstraintmodel.cpp.

hasConstraint() [1/2]

bool ConstraintModel::hasConstraint

(

const Constraint &

c

)

const

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

Definition at line 182 of file kganttconstraintmodel.cpp.

hasConstraint() [2/2]

bool KGantt::ConstraintModel::hasConstraint ( const QModelIndex & s, const QModelIndex & e ) const

inline

Definition at line 98 of file kganttconstraintmodel.h.

removeConstraint()

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.
