Detailed Description¶
To set the item’s line, pass a QLineF to
QGraphicsLineItem
‘s constructor, or call thesetLine()
function. Theline()
function returns the current line. By default the line is black with a width of 0, but you can change this by callingsetPen()
.QGraphicsLineItem
uses the line and the pen width to provide a reasonable implementation ofboundingRect()
,shape()
, andcontains()
. Thepaint()
function draws the line using the item’s associated pen.- __init__([parent=None])¶
