public class DrawableHTMLNode
extends DrawableSGMLNode
A generic Drawable HTML node is a set of nestable objects (e.g. components of a list, etc). As each subObject is drawn it determines where the next object starts and also increases the size of 'this' object's bounding box. Expansion is only vertical at present. the main present emphasis is hypertext page layout

Constructor Index

o DrawableHTMLNode()
create the DrawableHTMLNode
o DrawableHTMLNode(String, SGMLTree)

Method Index

o addSubObject(DrawableHTMLNode)
add a DrawableHTMLNode subObject ; could be overridden to validate types
o debug()
for debug
o display(Graphics)
displays the object to a pre-selected graphics context
o getCurrentY()
gets the y value after display
o main(String[])
o mouseUp(Event, int, int)
traps mouse clicks; if not dealt with by theDrawable, may be passed to other routines
o process()
complex objects may require processing; override this.
o process(Graphics, Scaler2D)
o setFont(Font)
set the font so the Paragraph remembers it
o toString()
returns (maybe recursively) the SGML representation of the node.
