PdfSearchModel provides the ability to search for text strings within a document and get the geometric locations of matches on each page.
The page on which currentMatchGeometry should provide filtered search results.
A set of paths in a form that can be bound to the
paths
property of a
PathMultiline
instance to render a batch of rectangles around all the regions where search results are found on
currentPage
:
PdfDocument { id: doc } PdfSearchModel { id: searchModel document: doc } Shape { ShapePath { PathMultiline { paths: searchModel.matchGeometry(view.currentPage) } } }
另请参阅 PathMultiline .
The result index on currentPage 其中 currentResultBoundingPolygons should provide the regions to highlight.
A set of paths in a form that can be bound to the
paths
property of a
PathMultiline
instance to render a batch of rectangles around the regions comprising the search result
currentResult
on
currentPage
. This is normally used to highlight one search result at a time, in a UI that allows stepping through the results:
PdfDocument { id: doc } PdfSearchModel { id: searchModel document: doc currentPage: view.currentPage currentResult: ... } Shape { ShapePath { PathMultiline { paths: searchModel.currentResultBoundingPolygons } } }

The bounding box containing all currentResultBoundingPolygons .
When this property changes, a scrollable view should automatically scroll itself in such a way as to ensure that this region is visible; for example, it could try to position the upper-left corner near the upper-left of its own viewport, subject to the constraints of the scrollable area.
The string to search for.
