Functions

◆ columnCount()

int QCompletionModel::columnCount ( const QModelIndex & parent = QModelIndex() ) const

virtual

Returns the number of columns for the children of the given parent.

In most subclasses, the number of columns is independent of the parent.

For example:

int DomModel::columnCount(const QModelIndex &/*parent*/) const
{
    return 3;
}

Note: When implementing a table based model, columnCount() should return 0 when the parent is valid.

◆ parent()

QModelIndex QCompletionModel::parent ( const QModelIndex & index = QModelIndex() ) const

inlinevirtual

Returns the parent of the model item with the given index.

Warning: This function is not part of the public interface.

If the item has no parent, an invalid QModelIndex is returned.

A common convention used in models that expose tree data structures is that only items in the first column have children. For that case, when reimplementing this function in a subclass the column of the returned QModelIndex would be 0.

When reimplementing this function in a subclass, be careful to avoid calling QModelIndex member functions, such as QModelIndex::parent(), since indexes belonging to your model will simply call your implementation, leading to infinite recursion.

◆ rowCount()

int QCompletionModel::rowCount ( const QModelIndex & parent = QModelIndex() ) const

virtual

Returns the number of rows under the given parent.

When the parent is valid it means that rowCount is returning the number of children of parent.

Note: When implementing a table based model, rowCount() should return 0 when the parent is valid.
