nsIAccessNode in Firefox 3.5

 An interface used by in-process accessibility clients
 to get style, window, markup and other information about
 a DOM node. When accessibility is active in Gecko,
 every DOM node can have one nsIAccessNode for each
 pres shell the DOM node is rendered in.
 The nsIAccessNode implementations are instantiated lazily.
 The nsIAccessNode tree for a given dom window
 has a one to one relationship to the DOM tree.
 If the DOM node for this access node is "accessible",
 then a QueryInterface to nsIAccessible will succeed.

Attributes

 The nsIAccessibleDocument that this nsIAccessNode
 resides in.

readonly attribute nsIAccessibleDocument accessibleDocument

 The DOM node this nsIAccessNode is associated with.

readonly attribute nsIDOMNode DOMNode

 The first nsIAccessNode child

readonly attribute nsIAccessNode firstChildNode

 The innerHTML for the DOM node
 This is a text string of all the markup inside the DOM
 node, not including the start and end tag for the node.

readonly attribute DOMString innerHTML

 The language for the current DOM node, e.g. en, de, etc.

readonly attribute DOMString language

 The last nsIAccessNode child

readonly attribute nsIAccessNode lastChildNode

 The next nsIAccessNode sibling

readonly attribute nsIAccessNode nextSiblingNode

 The number of DOM children for the DOM node, which
 matches the number of nsIAccessNode children for this
 nsIAccessNode.

readonly attribute long numChildren

 The OS window handle for the window this node
 is being displayed in.

[noscript] readonly attribute voidPtr ownerWindow

 The parent nsIAccessNode

readonly attribute nsIAccessNode parentNode

 The previous nsIAccessNode sibling

readonly attribute nsIAccessNode previousSiblingNode

 A unique ID calculated for this DOM node, for the 
 purposes of caching and referencing this object.

[noscript] readonly attribute voidPtr uniqueID

Methods

 Get the nth child of this node
 @param childNum Zero-based child index
 @return The nth nsIAccessNode child

nsIAccessNode getChildNodeAt(in long childNum)

 The method is similar to getComputedStyleValue() excepting that this one
 returns nsIDOMCSSPrimitiveValue.

nsIDOMCSSPrimitiveValue getComputedStyleCSSValue(in DOMString pseudoElt, in DOMString propertyName)

 Retrieve the computed style value for this DOM node, if it is a DOM element.
 Note: the meanings of width, height and other size measurements depend
 on the version of CSS being used. Therefore, for bounds information, 
 it is better to use nsIAccessible::accGetBounds.
 @param pseudoElt The pseudo element to retrieve style for, or NULL
                  for general computed style information for this node.
 @param propertyName Retrieve the computed style value for this property name,
                     for example "border-bottom".

DOMString getComputedStyleValue(in DOMString pseudoElt, in DOMString propertyName)

 Makes an object visible on screen.

 @param scrollType - defines where the object should be placed on
                     the screen (see nsIAccessibleScrollType for
                     available constants).

void scrollTo(in unsigned long aScrollType)

 Moves the top left of an object to a specified location.

 @param coordinateType - specifies whether the coordinates are relative to
                         the screen or the parent object (for available
                         constants refer to nsIAccessibleCoordinateType)
 @param aX - defines the x coordinate
 @param aY - defines the y coordinate

void scrollToPoint(in unsigned long aCoordinateType, in long aX, in long aY)
