Pyqt5 qpolygonf. 2); In addition to the functions provided by QVector, QPolygonF provides the boundingRect () and translate () functions for geometry operations. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. QPolygonF QGraphicsItem:: mapToItem (const QGraphicsItem * item, const QPolygonF & polygon) const Maps the polygon polygon, which is in this item's coordinate system, to item 's coordinate system, and returns the mapped polygon. We would like to show you a description here but the site won’t allow us. Detailed Description A QPolygonF is a QVector <QPointF>. QPolygonF also provides the isClosed () function to determine whether a polygon’s start and end points are the same, and the toPolygon () function returning an integer May 10, 2022 · I have the following QPolygon: and I need to increase its size in height to get a following QPolygon: whereas the lower boundary of the qpolygon stays in the same location, that is x1,y1 in the f QPolygonF also provides the isClosed() function to determine whether a polygon’s start and end points are the same, and the toPolygon() function returning an integer precision copy of this polygon. 4, 20. 首先，我们学习了NumPy和PySide的基本概念。 然后，我们使用示例代码演示了如何创建一个空的QPolygonF对象，并将数据从NumPy数组传输到QPolygonF对象中。 最后，我们介绍了一些性能优化的技巧，以提高传输数据的效率。 We would like to show you a description here but the site won’t allow us. Sep 13, 2025 · A QPolygonF is essentially a list of points (QPointF objects) that form a polygon. The polygon contains the four vertices of the rectangle in clockwise order starting and ending with the top-left vertex. ozcmm mvkkcap ylnh vpjaw gnszngrj lnqqt rtztkbl eqjfvngd npinsys aal
