public class JComponentView
extends JView
Component decorator that implements the view interface. The entire element is used to represent the component. This acts as a gateway from the display-only View implementations to interactive lightweight components (ie it allows components to be embedded into the View hierarchy. The parent of the component is the container that is handed out by the associated view factory.

Constructor Index

o JComponentView(Element, Component, ViewFactory)

Method Index

o changedUpdate(DocumentEvent, Shape, ViewFactory)
o getPreferredShape(Shape, ViewFactory)
Calculates the desired shape of the component.
o insertUpdate(DocumentEvent, Shape, ViewFactory)
o modelToView(Position, Shape, ViewFactory)
o paint(Graphics, Shape, ViewFactory)
The real paint behavior occurs naturally from the association that the component has with it's parent container (the same container hosting this view), so this simply allows us to position the component properly relative to the view.
o removeUpdate(DocumentEvent, Shape, ViewFactory)
o viewToModel(Point, Shape, ViewFactory)

Constructors

o JComponentView 
 public JComponentView(Element elem,
                       Component c,
                       ViewFactory f)

Methods

o paint 
 public void paint(Graphics g,
                   Shape a,
                   ViewFactory f)
The real paint behavior occurs naturally from the association that the component has with it's parent container (the same container hosting this view), so this simply allows us to position the component properly relative to the view. Since the coordinate system for the view is simply the parent containers, positioning the child component is easy.

o getPreferredShape 
 public Shape getPreferredShape(Shape candidate,
                                ViewFactory f)
Calculates the desired shape of the component. The preferred size of the component is used unless it doesn't fit within the parents constraints. If it doesn't fit, it shrinks the component to the maximum of either the constraint or the mimimum size.

getPreferredShape in class JView

o modelToView 
 public Shape modelToView(Position pos,
                          Shape a,
                          ViewFactory f) throws BadLocation
Throws: BadLocation
If the given position does not represent a valid location in the associated document.

                             Shape a,
