TDOMNode_WithChildren.InternalAppend procedure
Performs actions needed to append the specified node to the ChildNodes.
Declaration
procedure InternalAppend(NewChild: TDOMNode)Arguments
NewChild | New DOM Node appended to the DOM sub-tree. |
Description
InternalAppend is a method used to perform actions needed to
append the DOM node specified in
NewChild to the child nodes for
the class instance.
If the node has child nodes, as indicated by a value in
FirstChild, PreviousSibling and NextSibling
properties for the nodes are updated to reflect the new relationship in the
node hierarchy.
If the node does not have any existing child nodes, the value in NewChild is assigned to the FirstChild property.
In both cases, NewChild is used as the LastChild for the class
instance.
InternalAppend ensures that the ParentNode in NewChild is set to
the current class instance.
InternalAppend is used in the implementation of the CloneChildren method.
