#include <QGraphicsLineItem>
Inherits QGraphicsItem.
This class was introduced in Qt 4.2.
The QGraphicsLineItem class provides a line item that you can add to a QGraphicsScene.
To set the item's line, pass a QLineF to QGraphicsLineItem's constructor, or call setLine(). line() returns the current line. By default the line is black with a width of 1.0, but you can change this by calling setPen().
QGraphicsLineItem uses the line and the pen width to provide a reasonable implementation of boundingRect(), shape(), and contains(). The paint() function draws the line using the item's associated pen.

Constructs a QGraphicsLineItem. parent and scene are passed to QGraphicsItem's constructor.
Constructs a QGraphicsLineItem, using line as the default line. parent and scene are passed to QGraphicsItem's constructor.
Constructs a QGraphicsLineItem, using x1 y1 - x2 y2 as the default line. parent and scene are passed to QGraphicsItem's constructor.
Destroys the QGraphicsLineItem.
Returns the item's line, or QLineF() if no line has been set.

This is an overloaded member function, provided for convenience.
This is the same as calling setLine(QLineF(x1, y1, x2, y2)).
Sets the item's pen to pen. If no pen is set, the line will be painted using a black solid 0-width line.
