This signal is emitted when the contents have been created.
[signal] void QHelpContentModel::contentsCreationStarted()

See also isCreatingContents().
[override virtual] QHelpContentModel::~QHelpContentModel()
Destroys the help content model.
[override virtual] int QHelpContentModel::columnCount(const QModelIndex &parent = QModelIndex()) const
Reimplements: QAbstractItemModel::columnCount(const QModelIndex &parent) const.
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)
Creates new contents by querying the help system for contents specified for the customFilterName.
[override virtual] QVariant QHelpContentModel::data(const QModelIndex &index, int role) const
Reimplements: QAbstractItemModel::data(const QModelIndex &index, int role) const.
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
Returns true if the contents are currently rebuilt, otherwise false.
[override virtual] QModelIndex QHelpContentModel::parent(const QModelIndex &index) const
Reimplements: QAbstractItemModel::parent(const QModelIndex &index) const.
Returns the parent of the model item with the given index, or QModelIndex() if it has no parent.
[override virtual] int QHelpContentModel::rowCount(const QModelIndex &parent = QModelIndex()) const
Reimplements: QAbstractItemModel::rowCount(const QModelIndex &parent) const.
