addContentsItem()

void FTVHelp::addContentsItem ( bool isDir, const QCString & name, const QCString & ref, const QCString & file, const QCString & anchor, bool separateIndex, bool addToNavIndex, const Definition * def )

virtual

Add a list item to the contents file.

Parameters

isDir	TRUE if the item is a directory, FALSE if it is a text
name	the name of the item.
ref	the URL of to the item.
file	the file containing the definition of the item
anchor	the anchor within the file.
separateIndex	put the entries in a separate index file
addToNavIndex	add this entry to the quick navigation index
def	Definition corresponding to this entry

Implements IndexIntf.
