[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。

[override virtual]
QHelpContentModel::
~QHelpContentModel
()
Destroys the help content model.
[override virtual]
int
QHelpContentModel::
columnCount
(const
QModelIndex
&
parent
= QModelIndex()) const
重实现: QAbstractItemModel::columnCount (const QModelIndex &parent) const.
Returns the number of columns under the given parent . Currently returns always 1.
Returns the help content item at the model index position index .
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: 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

, const
QModelIndex
&
parent
= QModelIndex()) const
重实现: QAbstractItemModel::index (int row, int column, const QModelIndex &parent) const.
返回模型中的项索引,指定通过给定 row , column and parent 索引。
Returns true if the contents are currently rebuilt, otherwise false.
[override virtual]
QModelIndex
QHelpContentModel::
parent
(const
QModelIndex
&
index
) const
重实现: 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
重实现: QAbstractItemModel::rowCount (const QModelIndex &parent) const.
Returns the number of rows under the given parent .
