addString(String)

add a String - NO EOR assumed

debug()

for debug

display(Graphics)

displays the object to a pre-selected graphics context

display(Graphics, Component)

dummy at present until worked out

getCurrentY()

gets the y value after display

getScaler2D()

gets the Scaler2D context from the object (object must contain this)

isSelected()

and find out whether it is

mouseDown(Event, int, int)

traps mouse clicks; if not dealt with by theDrawable, may be passed to other routines such as MouseManager.

mouseDrag(Event, int, int)

traps mouse drags; if not dealt with by theDrawable, may be passed to other routines such as MouseManager.

mouseUp(Event, int, int)

traps mouse clicks; if not dealt with by theDrawable, may be passed to other routines

process(Graphics, Scaler2D)

processMouseBox(Int2Range)

requests the Drawable to take action after a mouseBox has been swept out .

setComponent(Component)

set the component so that graphics can be updated

setFont(Font)

set the font so the Paragraph remembers it

setHighlightable(boolean)

set the Drawable so that subaddresses are highlighted (marked) rather than take immediate action

setScaler2D(Scaler2D)

setSelected(boolean)

tell the object it has been selected (e.g.

  public Paragraph(String title)

create the Paragraph

  public void setComponent(Component c)

set the component so that graphics can be updated

  public void addString(String s)

add a String - NO EOR assumed

  public void addLine(String l)

add a line of text - EOR assumed (i.e. musn't be given)

  public void setFont(Font f)

set the font so the Paragraph remembers it

  public boolean mouseUp(Event evt,
                         int x,
                         int y)

traps mouse clicks; if not dealt with by theDrawable, may be passed to other routines

  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.

  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.

  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.

  public void display(Graphics g,
                      Component c)

dummy at present until worked out

  public void display(Graphics g)

displays the object to a pre-selected graphics context

  public int getCurrentY()

gets the y value after display

  public Scaler2D getScaler2D()

gets the Scaler2D context from the object (object must contain this)

  public void setScaler2D(Scaler2D s2d)

  public void setSelected(boolean selected)

tell the object it has been selected (e.g. by a mouse)

  public boolean isSelected()

and find out whether it is

  public boolean action(Event e,
                        Object arg)

pass any action events to theDrawable

  public void setHighlightable(boolean b)

set the Drawable so that subaddresses are highlighted (marked) rather than take immediate action

  public void process(Graphics g,
                      Scaler2D sc2d)

  public void debug()

for debug
