\qmltype PdfLinkDelegate
\inqmlmodule QtQuick.Pdf
\brief A component to decorate hyperlinks on a PDF page.
PdfLinkDelegate provides the component that QML-based PDF viewers
instantiate on top of each hyperlink that is found on each PDF page.
This component does not provide any visual decoration, because often the
hyperlinks will already be formatted in a distinctive way; but when the
mouse cursor hovers, it changes to Qt::PointingHandCursor, and a tooltip
appears after a delay. Clicking emits the goToLocation() signal if the link
is internal, or calls Qt.openUrlExternally() if the link contains a URL.
