QPersistentModelIndex::QPersistentModelIndex ( const QModelIndex & index )

Creates a new QPersistentModelIndex that is a copy of the model index.

QPersistentModelIndex::QPersistentModelIndex ( const QPersistentModelIndex & other )

Creates a new QPersistentModelIndex that is a copy of the other persistent model index.

QModelIndex QPersistentModelIndex::child ( int row, int column ) const

Returns the child of the model index that is stored in the given row and column.

See also parent() and sibling().

int QPersistentModelIndex::column () const

Returns the column this persistent model index refers to.

QVariant QPersistentModelIndex::data ( int role = Qt::DisplayRole ) const

Returns the data for the given role for the item referred to by the index.

See also Qt::ItemDataRole and QAbstractItemModel::setData().

Qt::ItemFlags QPersistentModelIndex::flags () const

Returns the flags for the item referred to by the index.

This function was introduced in Qt 4.2.

bool QPersistentModelIndex::isValid () const

Returns true if this persistent model index is valid; otherwise returns false.

A valid index belongs to a model, and has non-negative row and column numbers.

See also model(), row(), and column().

const QAbstractItemModel * QPersistentModelIndex::model () const

Returns the model that the index belongs to.

QModelIndex QPersistentModelIndex::parent () const

Returns the parent QModelIndex for this persistent index, or an invalid QModelIndex if it has no parent.

See also child(), sibling(), and model().

int QPersistentModelIndex::row () const

Returns the row this persistent model index refers to.

QModelIndex QPersistentModelIndex::sibling ( int row, int column ) const

Returns the sibling at row and column or an invalid QModelIndex if there is no sibling at this position.

See also parent() and child().

QPersistentModelIndex::operator const QModelIndex & () const

Cast operator that returns a const QModelIndex&.

bool QPersistentModelIndex::operator!= ( const QPersistentModelIndex & other ) const

Returns true if this persistent model index is not equal to the other persistent model index; otherwise returns false.

This function was introduced in Qt 4.2.

bool QPersistentModelIndex::operator!= ( const QModelIndex & other ) const

Returns true if this persistent model index does not refer to the same location as the other model index; otherwise returns false.

bool QPersistentModelIndex::operator< ( const QPersistentModelIndex & other ) const

Returns true if this persistent model index is smaller than the other persistent model index; otherwise returns false.

All values in the persistent model index are used when comparing with another persistent model index.

This function was introduced in Qt 4.1.

QPersistentModelIndex & QPersistentModelIndex::operator= ( const QPersistentModelIndex & other )

Sets the persistent model index to refer to the same item in a model as the other persistent model index.

QPersistentModelIndex & QPersistentModelIndex::operator= ( const QModelIndex & other )

Sets the persistent model index to refer to the same item in a model as the other model index.

bool QPersistentModelIndex::operator== ( const QPersistentModelIndex & other ) const

Returns true if this persistent model index is equal to the other persistent model index; otherwise returns false.

All values in the persistent model index are used when comparing with another persistent model index.

bool QPersistentModelIndex::operator== ( const QModelIndex & other ) const

Returns true if this persistent model index refers to the same location as the other model index; otherwise returns false.

All values in the persistent model index are used when comparing with another model index.
