Detailed Description#
To set the item’s line, pass a QLineF to QGraphicsLineItem ‘s constructor, or call the setLine() function. The line() function returns the current line. By default the line is black with a width of 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.
