Detailed Description

Line item.

Compared to QGraphicsLineItem, this class has following improvements:

Selection is drawn as a line instead as a bounding rectangle.
The shape is created with a line width of 1 in stead of 0 when the pen size is 0, otherwise single selection would not work.
Additional methods p1(), p2(), setP1() and setP2() to directly access the two points.
