Qt qlinef intersect
http://man.hubwiz.com/docset/Qt_5.docset/Contents/Resources/Documents/doc.qt.io/qt-5/qlinef.html WebUse the isNull () function to determine whether the QLineF represents a valid line or a null line. The intersect () function determines the IntersectType for this line and a given line, while the angle () function returns the angle between the lines.
