`[explicit]` QPdfLinkModel:: QPdfLinkModel ( QObject * parent = nullptr)

Constructs a new link model with parent object parent .

`[override virtual noexcept]` QPdfLinkModel:: ~QPdfLinkModel ()

Destroys the model.

`[override virtual]` QVariant QPdfLinkModel:: data (const QModelIndex & index , int role ) const

重实现： QAbstractItemModel::data(const QModelIndex &index, int role) const .

QPdfLink QPdfLinkModel:: linkAt ( QPointF point ) const

返回 valid link if found under the point (given in units of points, 1/72 of an inch), or an invalid link if it is not found. In other words, this function is useful for picking, to handle mouse click or hover.

`[override virtual]` int QPdfLinkModel:: rowCount (const QModelIndex & parent ) const

重实现： QAbstractItemModel::rowCount(const QModelIndex &parent) const .
