from PySide.QtCore import QLineF, QPointF start = QPointF(0, 0) end = QPointF(100, 100) line = QLineF(start, end)
from PySide.QtCore import QLineF line = QLineF.fromPolar(50, 45)
from PySide.QtCore import QLineF line1 = QLineF(0, 0, 100, 100) line2 = QLineF(50, 0, 50, 100) if line1.intersect(line2, QPointF()): print("The lines intersect!") else: print("The lines do not intersect.")This code creates two QLineF objects and checks if they intersect. If they do, it prints a message indicating that they intersect. Otherwise, it prints a message saying that they do not. Overall, PySide QtCore is a package library that provides a variety of classes for creating GUI applications using the Qt framework, including the QLineF class for working with straight lines.
