bounds : const QVector < QPolygonF >

This property holds a set of regions that the selected text occupies on the page, represented as polygons. The coordinate system for the polygons has the origin at the upper-left corner of the page, and the units are points .

注意: For now, the polygons returned from QPdfDocument::getSelection () are always rectangles; but in the future it may be possible to represent more complex regions.
