Class GraphUnitLayout

java.lang.Object

javax.swing.SpringLayout

kcl.waterloo.swing.layout.GraphUnitLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.awt.LayoutManager2

Direct Known Subclasses:

GraphContainerLayout, GraphLayout

public abstract class GraphUnitLayout
extends javax.swing.SpringLayout

GraphUnitLayout extends SpringLayout to provide support for components that are positioned in graph coordinate space. Use the putGraphicConstraint method to add components in graph space. Note that the putConstraint method may still be used to position components using pixel coordinates. GraphUnitLayout is an abstract class.

Method Detail

putGraphicConstraint

public void putGraphicConstraint(java.awt.Component c,
                        double x,
                        double y,
                        int alignX,
                        int alignY)

Registers the specified component to be laid out using graph units.

Parameters:

c - the Component

x - x-position in graph units

y - y-position in graph units

alignX - relative X alignment specified using a SwingConstants value.

alignY - relative Y alignment specified using a SwingConstants value.

getComponentMap

public java.util.LinkedHashMap<java.awt.Component,GraphicConstraint> getComponentMap()

Returns the LinkedHashMap of Components to be laid out using graph coordinates.

Returns:

the LinkedHashMap of Components

setComponentMap

public void setComponentMap(java.util.LinkedHashMap<java.awt.Component,GraphicConstraint> map)

Adds the input to the existing component map. Entries for components already present will be updated. Entries for components not present in the existing componenMap will be added.

Parameters:

map -

getDimensions

public java.util.ArrayList<java.awt.Dimension> getDimensions()

Returns an ArrayList of the preferredSize of each component in the componentMap. This method will be used in serialization/deserialization to preserve the dimensions of Swing annotations.

Returns:

ArrayList of Dimensions

setDimensions

public void setDimensions(java.util.ArrayList<java.awt.Dimension> dim)

Sets the dimensions of components in the componentMap. The input size must match the componentMap size.This method will be used in serialization/deserialization to preserve the dimensions of Swing annotations.

Parameters:

dim - ArrayList of Dimensions

revalidateComponent

protected final void revalidateComponent(java.awt.Component c,
                       GJAbstractGraphContainer container,
                       GJGraphInterface gr,
                       boolean translateCoordinates)

doSuperLayoutContainer

public void doSuperLayoutContainer(java.awt.Container c)

This method does nothing and needs to be overridden.

Parameters:

c -
