Returns the number of columns under the given parent. Currently returns always 1.

QHelpContentItem *QHelpContentModel::contentItemAt(const QModelIndex &index) const

Returns the help content item at the model index position index.

void QHelpContentModel::createContents(const QString &customFilterName)

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

[override virtual] QModelIndex QHelpContentModel::index(int row, int column, const QModelIndex &parent = QModelIndex()) const

Reimplements: QAbstractItemModel::index(int row, int column, const QModelIndex &parent) const.

Returns the index of the item in the model specified by the given row, column and parent index.

bool QHelpContentModel::isCreatingContents() const
