成员函数文档编制

[override virtual] QHelpContentModel:: ~QHelpContentModel ()

Destroys the help content model.

[override virtual] int QHelpContentModel:: columnCount (const QModelIndex & parent = QModelIndex()) const

重实现自 QAbstractItemModel::columnCount ().

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 () 被发射。

另请参阅 isCreatingContents ().

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

重实现自 QAbstractItemModel::data ().

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

重实现自 QAbstractItemModel::index ().

返回模型中的项索引，指定通过给定 row , column and parent 索引。

bool QHelpContentModel:: isCreatingContents () const

Returns true if the contents are currently rebuilt, otherwise false.

[override virtual] QModelIndex QHelpContentModel:: parent (const QModelIndex & index ) const

重实现自 QAbstractItemModel::parent ().

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

重实现自 QAbstractItemModel::rowCount ().

Returns the number of rows under the given parent .
