public class SimpleText
extends Object
implements Drawable
A text area which can be drawn onto a Graphics area (as opposed to a TextArea which is a component. SimpleTexts are composed of one or more Paragraphs, which are generic containers for paragrahps, list items, etc. (A paragraph is the smallest coherent chunk of text - yes, I'm sure there's a better name (?Block)

Variable Index

o BOTTOM
o LEFT
o RIGHT
o TOP

Constructor Index

o SimpleText(String)
create the SimpleText and remember what component it is being drawn on

Method Index

o action(Event, Object)
pass any action events to theDrawable
o addElement(Paragraph)
add a Paragraph child to a SimpleText.
o debug()
for debug
o display(Graphics)
displays the object to a pre-selected graphics context
o display(Graphics, Component)
dummy at present until worked out
o getCurrentY()
gets the y value after display
o getScaler2D()
gets the Scaler2D context from the object (object must contain this)
o isSelected()
and find out whether it is
o mouseDown(Event, int, int)
traps mouse clicks; if not dealt with by theDrawable, may be passed to other routines such as MouseManager.
o mouseDrag(Event, int, int)
traps mouse drags; if not dealt with by theDrawable, may be passed to other routines such as MouseManager.
o mouseUp(Event, int, int)
traps mouse clicks; if not dealt with by theDrawable, may be passed to other routines
o process(Graphics, Scaler2D)
o processMouseBox(Int2Range)
requests the Drawable to take action after a mouseBox has been swept out .
o setComponent(Component)
set the component (recursively) so that graphics can be updated
o setHighlightable(boolean)
set the Drawable so that subaddresses are highlighted (marked) rather than take immediate action
o setScaler2D(Scaler2D)
set the scaling module
o setSelected(boolean)
tell the object it has been selected (e.g.

Variables

o TOP 
  public final static int TOP
o LEFT 
  public final static int LEFT
o BOTTOM 
  public final static int BOTTOM
o RIGHT 
  public final static int RIGHT

Constructors

o SimpleText 
  public SimpleText(String title)
create the SimpleText and remember what component it is being drawn on

Methods

o setComponent 
  public void setComponent(Component c)
set the component (recursively) so that graphics can be updated
o addElement 
  public void addElement(Paragraph p)
add a Paragraph child to a SimpleText.
o mouseUp 
  public boolean mouseUp(Event evt,
                         int x,
                         int y)
traps mouse clicks; if not dealt with by theDrawable, may be passed to other routines
o mouseDrag 
  public boolean mouseDrag(Event evt,
                           int x,
                           int y)
traps mouse drags; if not dealt with by theDrawable, may be passed to other routines such as MouseManager.
o mouseDown 
  public boolean mouseDown(Event evt,
                           int x,
                           int y)
traps mouse clicks; if not dealt with by theDrawable, may be passed to other routines such as MouseManager.
o processMouseBox 
  public boolean processMouseBox(Int2Range box)
requests the Drawable to take action after a mouseBox has been swept out . The two commonest actions are to select a portion and zoom, or to return a set of subaddresses from the object.
o setScaler2D 
  public void setScaler2D(Scaler2D s)
set the scaling module
o display 
  public void display(Graphics g,
                      Component c)
dummy at present until worked out
o display 
  public void display(Graphics g)
displays the object to a pre-selected graphics context
o getCurrentY 
  public int getCurrentY()
gets the y value after display
o getScaler2D 
  public Scaler2D getScaler2D()
gets the Scaler2D context from the object (object must contain this)
o setSelected 
  public void setSelected(boolean selected)
tell the object it has been selected (e.g. by a mouse)
o isSelected 
  public boolean isSelected()
and find out whether it is
o action 
  public boolean action(Event e,
                        Object arg)
pass any action events to theDrawable
o setHighlightable 
  public void setHighlightable(boolean b)
set the Drawable so that subaddresses are highlighted (marked) rather than take immediate action
o process 
  public void process(Graphics g,
                      Scaler2D sc2d)
o debug 
  public void debug()
for debug
