All Implemented Interfaces:
  java.lang.Cloneable

public class IRootAbs
extends INode

Method Summary
`boolean` | `eventNode(java.awt.AWTEvent e, java.awt.Point rel)` Never claims `Browser.setCurNode(Node, int)` itself.
`boolean` | `formatBeforeAfter(int width, int height, Context cx)` Internal nodes might have a structural style LATER: externalize format to a behavior and choose with style sheet.
`boolean` | `formatNode(int width, int height, Context cx)` Children report dimensions (width and height), parent places at (x,y).

Constructor Detail

### IRootAbs

    public IRootAbs()

### IRootAbs

    public IRootAbs(java.lang.String name,
                    java.util.Map<java.lang.String,java.lang.Object> attr,
                    INode parent)

Method Detail

### formatBeforeAfter

    public boolean formatBeforeAfter(int width,
                                     int height,
                                     Context cx)

  Description copied from class: `INode`
  Internal nodes might have a structural style LATER: externalize format to a behavior and choose with style sheet.

  Overrides:
    `formatBeforeAfter` in class `INode`
  Parameters:
    `width` - of screen, or fraction thereof available to be taken by node
    `height` - of screen, or fraction thereof available to be taken by node (largely ignored in HTML, which has infinitely long scroll, except in FRAME)
  See Also:
    `Behavior`

### formatNode

    public boolean formatNode(int width,
                              int height,
                              Context cx)

  Description copied from class: `INode`
  Children report dimensions (width and height), parent places at (x,y). Bbox = union of children's bboxes Children stacked vertically like TeX vbox; override to implement other layout strategies To implement a new layout manager, override this method.

  Overrides:
    `formatNode` in class `INode`
  See Also:
    `FixedI`

### eventNode

    public boolean eventNode(java.awt.AWTEvent e,
                             java.awt.Point rel)

  Never claims `Browser.setCurNode(Node, int)` itself.

  Overrides:
    `eventNode` in class `INode`
  See Also:
    `TreeEvent`, `SemanticEvent`
