Package weka.gui.treevisualizer

Class TreeVisualizer

  • All Implemented Interfaces:
    java.awt.event.ActionListener, java.awt.event.ItemListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible, PrintableHandler
    public class TreeVisualizer
extends PrintablePanel
implements java.awt.event.MouseMotionListener, java.awt.event.MouseListener, java.awt.event.ActionListener, java.awt.event.ItemListener
    Class for displaying a Node structure in Swing.

    To work this class simply create an instance of it.

    Assign it to a window or other such object.

    Resize it to the desired size.

    When using the Displayer hold the left mouse button to drag the tree around.

    Click the left mouse button with ctrl to shrink the size of the tree by half.

    Click and drag with the left mouse button and shift to draw a box, when the left mouse button is released the contents of the box will be magnified to fill the screen.

    Click the right mouse button to bring up a menu.

    Most options are self explanatory.

    Select Auto Scale to set the tree to it's optimal display size.
