Detailed Description

The most basic net to display the standard nets.

The GraphicsNet that is (currently) used to display nets in the scene. It provides functions to build up a net line by line (using the Lines struct).

Definition at line 44 of file standard_graphics_net.h.

Constructor & Destructor Documentation

◆ StandardGraphicsNet()

hal::StandardGraphicsNet::StandardGraphicsNet	(	Net *	n,

		const QList< QPointF > &	knots = `QList<QPointF>()`
	)

Constructor.

Parameters

n	- The undelying net of the StandardGraphicsNet
l	- The lines this GraphicsNet consists of
