Class LeafShadow

    java.lang.Object
      multivalent.VObject
          multivalent.Node
              multivalent.Leaf
                  multivalent.node.LeafShadow

All Implemented Interfaces:
  java.lang.Cloneable

public class LeafShadow
extends Leaf

Leaf to shadow structural node in absolute visual space. The document tree is primarily structural, but elements such as floats and menus cut across structure when painted. The node itself is a shadow, but it takes another node to shadow, so it operates as kind of an internal node too.

Constructor Detail

### LeafShadow

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

Method Detail

### getShadowed

    public Node getShadowed()

### formatBeforeAfter

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

  Description copied from class: `Node`
  In the depth-first tree traversal to format tree, Before and after methods of behavior observers invoked here; actual formatting passed on to formatNode(). In documents with layed out content, children set their dimensions and parents set their location. In documents with absolutely positioned content, usually leaves position themselves and internal nodes compute relative coordinates. If node is valid, its entire subtree is assumed formatted and this method returns without doing anything. Behavior observers return `true` to shortcircuit traversal of subtree, which this method on Node passes back up the tree.

  Overrides:
    `formatBeforeAfter` in class `Leaf`
  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: `Leaf`
  Handles span transitions on node and elided portions. Called medium-specific leaf formatNodeContent in hunks of maximum-length homogeneous span coverage to get content size. Marks node valid, so if node not (e.g., LeafImage's image not loaded), set valid_=false in formatNodeContent.

  Overrides:
    `formatNode` in class `Leaf`

### paintNode

    public void paintNode(java.awt.Rectangle docclip,
                          Context cx)

  Description copied from class: `Leaf`
  Call paintNodeContent with longest range of unchanged Context.

  Overrides:
    `paintNode` in class `Leaf`

### eventNode

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

  Description copied from class: `Leaf`
  unless overridden, leaves see if owner is interested

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