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.
readonly nsIAccessibleDocument accessibleDocument
The nsIAccessibleDocument that this nsIAccessNode resides in.
readonly nsIDOMNode DOMNode
The DOM node this nsIAccessNode is associated with.
readonly nsIAccessNode firstChildNode
The first nsIAccessNode child
readonly DOMString innerHTML
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 nsIAccessNode lastChildNode
The last nsIAccessNode child
readonly nsIAccessNode nextSiblingNode
The next nsIAccessNode sibling
readonly PRInt32 numChildren
The number of DOM children for the DOM node, which matches the number of nsIAccessNode children for this nsIAccessNode.
readonly voidPtr* ownerWindow
The OS window handle for the window this node is being displayed in.
readonly nsIAccessNode parentNode
The parent nsIAccessNode
readonly nsIAccessNode previousSiblingNode
The previous nsIAccessNode sibling
readonly voidPtr* uniqueID
A unique ID calculated for this DOM node, for the purposes of caching and referencing this object.
Get the nth child of this node
- childNum: Zero-based child index
- nsIAccessNode child
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.
- pseudoElt: The pseudo element to retrieve style for, or NULL for general computed style information for this node.
- propertyName: Retrieve the computed style value for this property name, for example "border-bottom".
