QHelpContentModel:: ~QHelpContentModel ()

Destroys the help content model.

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

重實現自 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 () 發射。

另請參閱 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

重實現自 QAbstractItemModel::data ().

返迴的數據存儲在給定 role 為項引用通過 index .

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

重實現自 QAbstractItemModel::index ().

返迴模型中的項索引，指定通過給定 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

重實現自 QAbstractItemModel::parent ().

返迴模型項的父級采用給定 index , or QModelIndex() if it has no parent.

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

重實現自 QAbstractItemModel::rowCount ().

Returns the number of rows under the given parent .
