詳細描述

PdfPageView provides a PDF viewer component that shows one whole page at a time, without scrolling. It supports selecting text and copying it to the clipboard, zooming in and out, clicking an internal link to jump to another section in the document, rotating the view, and searching for text.

The implementation is a QML assembly of smaller building blocks that are available separately. In case you want to make changes in your own version of this component, you can copy the QML, which is installed into the QtQuick/Pdf/qml 模塊目錄，並按需修改它。
