## Detailed Description

## Member Function Documentation

### `[override virtual noexcept]` QHelpContentModel::~QHelpContentModel()

Destroys the help content model.

### `[override virtual]` int QHelpContentModel::columnCount(const QModelIndex &parent = {}) 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.

### `[signal]` void QHelpContentModel::contentsCreated()

This signal is emitted when the contents have been created.

### `[signal]` void QHelpContentModel::contentsCreationStarted()

This signal is emitted when the creation of the contents has started. The current contents are invalid from this point on until the signal contentsCreated() is emitted.

See also isCreatingContents().

### void QHelpContentModel::createContents(const QString &filter)

Creates new contents by querying the help system for contents specified for the custom filter name.

### `[since 6.8]` void QHelpContentModel::createContentsForCurrentFilter()

Creates new contents by querying the help system for contents specified for the current filter.

This function was introduced in Qt 6.8.

### `[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 = {}) 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 = {}) const

Reimplements: QAbstractItemModel::rowCount(const QModelIndex &parent) const.

Returns the number of rows under the given parent.
