Detailed Description

Abstraction for the routing of a connector.

NB: As a general rule of thumb, the point references stored as members of this class are in Cell-space (i.e. 8^2 x smaller than Canvas-space), and the interfacing functions take or give point references in Canvas-space (unless otherwise indicated).

void ConRouter::mapRoute	(	int	sx,
		int	sy,
		int	ex,
		int	ey
	)

What this class is all about - finding a route, from (sx,sy) to (ex,ey).

void ConRouter::translateRoute	(	int	dx,
		int	dy
	)

Translates the precalculated routepoints by the given amount

void ConRouter::setPoints	(	const QPointList &	pointList,
		bool	reverse = false
	)

Sets the route to the given canvas points

Parameters:

reverse

if true, the points in pointList will be reversed

bool ConRouter::needsRouting	(	int	sx,

Returns:

true if the start or end points differ from that of the current route
