Overview ¶

Package layout is the port through which the workspace graph is placed for drawing. The engine asks a Layout where each node goes and every interface draws what it is told, so the graph looks the same in each; the force adapter beside this package is the one implementation today.

Types ¶

type Edge ¶

type Edge struct {
	S, T int
}

Edge joins two nodes, by their index in the nodes passed.

type Func ¶

type Func func(nodes []Node, edges []Edge) []Point

Func adapts a function to the Layout interface.

func (Func) Place ¶

func (f Func) Place(nodes []Node, edges []Edge) []Point

Place calls f.

type Layout ¶

type Layout interface {
	// Place returns one point per node, in the order of nodes.
	Place(nodes []Node, edges []Edge) []Point
}

Layout places a graph. The same nodes and edges in the same order are always placed the same way, so a graph asked for twice, or by two interfaces, is drawn alike.

type Node ¶

type Node struct {
	// Group gathers nodes that belong together (the engine passes a
	// kind's place in its order); a layout keeps a group near itself.
	Group int
}

Node is one thing to place.

type Point ¶

type Point struct {
	X, Y float64
}

Point is where a node goes, in units an interface scales to its screen.

conformance Package conformance is what every layout.Layout must do: place every node somewhere finite, the same way every time, keep what is connected nearer than what is not, and keep a group together.

force Package force is a force-directed Layout: edges are springs, nodes push apart at short range, and each group drifts towards its own place on a ring, so the same kinds gather and a node sits between what it connects.

layered Package layered is a Layout for a directed acyclic graph: each group is a layer, drawn as a band from the top down in the order the engine numbers them, so every edge runs from a band to one above it or along its own.
