Constructor Detail

BasicGraphPanel

public BasicGraphPanel(MedusaSettings stringSettings)

Constructs a new BasicGraphPanel with settings

Parameters:

stringSettings - settings

BasicGraphPanel

public BasicGraphPanel()

Method Detail

setGraph

public void setGraph(Graph g)

updateNodes

public void updateNodes()

Updates the nodes for quicker repainting

getPick

public Node getPick()

isRunning

public boolean isRunning()

setHideWhenMove

public void setHideWhenMove(boolean trueOrFalse)

If true, only the moving nodes will be displayed. This can be good if you have a large graph, since repainting will occur.

Parameters:

trueOrFalse - True if hide, False (default) if show all nodes while moving

setAlpha

public void setAlpha(boolean trueOrFalse)

Setting this to true results in a composite effect on edges based on the confidence level of the edge.

Parameters:

trueOrFalse - True if edges are displayed with alpha

changeFont

public void changeFont(int size)

Set font size

Parameters:

size - Font size

setNodeSize

public void setNodeSize(int nodeSize)

Set node size

Parameters:

nodeSize - Node size in pixels

setBackgroundColor

public void setBackgroundColor(java.awt.Color c)

Background color

Parameters:

c - Color c

Gets a color as a string

Parameters:

color - Color color

Returns:

String representation of color

setPretty

public void setPretty(boolean trueOrFalse)

If pretty is selected, multiple edges will be drawn in colors. If not selected, edges are drawn as unique edges and in grey.

Parameters:

trueOrFalse - Boolean pretty

setArrows

public void setArrows(boolean trueOrFalse)

Set true if you want to show edges as directed.

Parameters:

trueOrFalse - Boolean arrows or not

Sets the font color

Parameters:

setColor

public void setColor(java.lang.Integer i,
                     java.awt.Color color)

public double getEdgeLen()

Returns the current edge length

Returns:

edge length

calculateEdgeLength

public void calculateEdgeLength()
