详细描述

PdfSearchModel provides the ability to search for text strings within a document and get the geometric locations of matches on each page.

特性文档编制

currentPage : int

The page on which currentMatchGeometry should provide filtered search results.

currentPageBoundingPolygons : list < list < point >>

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)
        }
    }
}

currentResult : int

The result index on currentPage 其中 currentResultBoundingPolygons should provide the regions to highlight.

currentResultBoundingPolygons : list < list < point >>

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
        }
    }
}

currentResultBoundingRect : point

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.

searchString : string

The string to search for.
