Synopsis

Functions

• def line ()

• def pen ()

• def setLine (line)

• def setLine (x1, y1, x2, y2)

• def setPen (pen)

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.
