Detailed Description

This class gets nodes and searchs inside of 'info files'.

Each info file has nodes. Every node has the documentation. Info files contains a map with position of each node.

What is position? There is a simple answer: If you make a queue with info files, position will be the number of bytes from begining to node position.

But is not so easy. There is headers, and qtinfo must not take these headers into account.

This class also translates info files to html.

int parser::is_ref

(

const QString &

node

)

Checks if this node is reference.

If node is reference, it will be returned its position in text, else it will be returned -1.

QString parser::node_text_to_html	(	const QString &	text,
		int	anchorPos = -1,
		const QString &	anchor = QString ()
	)

Translates text of node to Html.

If anchorPos is not -1, then anchor is inserted in that position.
