Detailed Description

This is used in the Model/View Programming paradigm to display a list of search results, to highlight them on the rendered PDF pages, and to iterate through them using the "search forward" / "search backward" buttons and shortcuts that would be found in a typical document-viewing UI:

Member Type Documentation

Member Function Documentation

[explicit] QPdfSearchModel::QPdfSearchModel(QObject *parent)

Constructs a new search model with parent object parent.

[override virtual noexcept] QPdfSearchModel::~QPdfSearchModel()

Destroys the model.

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

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

QPdfLink QPdfSearchModel::resultAtIndex(int index) const

Returns a result found by index in the document, regardless of the page on which it was found. index must be less than rowCount.

QList<QPdfLink> QPdfSearchModel::resultsOnPage(int page) const

Returns the list of all results found on the given page.

[override virtual] QHash<int, QByteArray> QPdfSearchModel::roleNames() const

Reimplements: QAbstractItemModel::roleNames() const.

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

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

The number of rows in the model is equal to the number of search results found.
