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.
