          javax.swing.JComponent
              javax.swing.JPanel
                  RTree

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class RTree
extends javax.swing.JPanel

The RTree is a JPanel that draws a recursive tree according to the specification of CSC 210 program #1. There are 3 steps to use this class 1) You construct the RTree, 2) then use modifiers to change the appearance, and 3) paint it. There's also a main() test driver function at the bottom to show you how to use this guy.

Constructor Detail

RTree

public RTree()

Construct an RTree with default settings for order, angleDelta, and length factor. Use modifiers to change how your recursive tree appears

Method Detail

getOrder

public int getOrder()

Gets the order field

setOrder

public void setOrder(int o)

Sets the order field

Parameters:

o - the new order value... if param < 1, then order is left unchanged

getLengthFactor

public double getLengthFactor()

Gets the lengthFactor field

setLengthFactor

public void setLengthFactor(double f)

Sets the lengthFactor field

Parameters:

f - the new factor value... if param is < 0.0, then lengthFactor is left unchanged

getAngleDelta

public double getAngleDelta()

Gets the angleDelta field

setAngleDelta

public void setAngleDelta(double a)

Sets the angleDelta field... if param < 0, the angleDelta is left unchanged.

Parameters:

a - the new angle change for new branches, specified in degrees

paintComponent

public void paintComponent(java.awt.Graphics g)

Paints the component when it changes, ala Swing API. The recursive tree is drawn on the Graphics object provided.

Overrides:

paintComponent in class javax.swing.JComponent

Parameters:

g - The Graphics object where the tree is drawn

drawTree

public void drawTree(int order,
                     int x,
                     int y,
                     int len,
                     double angle,
                     java.awt.Graphics g)

Recursively draws the RTree. A recursive tree is a branch followed by two (or more) recursively built sub-branches.

Parameters:

order - the recursive order or depth of the tree, recursion stops a <= 0

x - (x,y) location of current branch

y - (x,y) location of current branch

len - length of current branch; this is changed by lengthFactor for each new branch/level of recursion

angle - angle of current branch; this is change by angleDelta for each new branch/level of recursion

g - The Graphics object where the tree is drawn

main

public static void main(java.lang.String[] args)

Test driver, absolutely bare bones, just to show how this can be used.

Parameters:

args - Unused
