QPointF point(3.0, 5.0); // create a point with x=3.0 and y=5.0 point.setY(7.0); // set the y-coordinate to 7.0
QListThis code creates a list of QPointF objects with different coordinates, and then loops through each point and adds 1.0 to its y-coordinate using the setY function. The package library used in these examples is Qt, which is a C++ framework for cross-platform application development.points = {QPointF(1.0, 2.0), QPointF(3.0, 4.0), QPointF(5.0, 6.0)}; for (auto& point : points) { point.setY(point.y() + 1.0); // add 1.0 to the y-coordinate of each point }
