Field Detail

logger

static org.apache.log4j.Logger logger

log4j facility

firstPort

protected org.jgraph.graph.PortView firstPort

first position of the edge

lastPort

protected org.jgraph.graph.PortView lastPort

last position of the edge

remanent

protected boolean remanent

A boolean telling wether or not a button creating an Edge or a Vertex should be remanent or not. If true, then you will continue with this button selectionned while if false you will the selection action will be restored after you added a cell.

addVertexnPorts

public org.jgraph.graph.GraphCell addVertexnPorts(java.awt.geom.Rectangle2D bounds)

This is a convenient hook to automatically add a cell, its ports and a custom user object. Especially override in priority some of the other methods of this class in order to meet your needs.

Parameters:

bounds -

hasFlottingPort

public boolean hasFlottingPort()

By default there aren't any floatting port. If you want some, then you will get a better graphical result by implementing the getPerimeterPoint method in the renderer of the cell view.

Returns:

boolean

getPortName

public java.lang.String getPortName(int i)

Unless the cell is created with differenciated port names, ports are all called undifferenciated_port followed by the i indice.

Parameters:

i - int

Returns:

String

getAttributeMap

public org.jgraph.graph.AttributeMap getAttributeMap(org.jgraph.graph.GraphCell cell,
                                                     java.awt.geom.Rectangle2D bounds)

You can override how the view attributes of the cell are created

Parameters:

cell -

bounds -

Returns:

a new attribute map with the defined bounds

reSize

protected java.awt.geom.Rectangle2D reSize(java.awt.geom.Rectangle2D bounds)

By default we don't resize the cell but this may be be overriden in order to implement an automatic resizing...

Parameters:

bounds -

Returns:

the resized rectangle

getXPortsList

public double[] getXPortsList()

By default a cell don't have ports

Returns:

double[]

getYPortsList

public double[] getYPortsList()

By default a cell don't have ports

Returns:

double[]
