Detailed Description

This Class Provides HTML/XML TreeModel for QTreeWidget or QTreeView. A parsed and, optionally, repaired document is represented by QTidyXHtmlTree. If given Document is not like a W3C DOM, no output generated.

 QTreeView *m_QTreeView = new QTreeView ( this );
 connect ( m_QTreeView, SIGNAL ( clicked ( const QModelIndex & ) ),
         this, SLOT ( selectionChanged ( const QModelIndex & ) ) );

 QTidy::QTidyXHtmlTree *tree = new QTidy::QTidyXHtmlTree ( this );
 // Don't forget to reset() your QTree(Widget|View) when using Q_SLOTS.
 if ( tree->setContent ( m_QTextDocument->toHtml() ) )
 {
   // Optional: you can use firstSiblings, if the Element not exits
   // and Document is wellformed then it returns the full document model.
   m_QTreeView->setModel ( tree->model( "body" ) );
   m_QTreeView->expandAll();
 }

How can i access the data model? QtidyXHtmlTree writing data to Qt::DisplayRole and Qt::EditRole.

• Qt::DislpayRole QString: Containing the QDomNode::nodeName().
• Qt::EditRole struct: Containing QTidy::QTidyNodeRole

 QTreeView *m_QTreeView = new QTreeView ( this );
 ...
 connect ( m_QTreeView, SIGNAL ( clicked ( const QModelIndex & ) ),
         this, SLOT ( selectionChanged ( const QModelIndex & ) ) );
 ...
 void myClass::selectionChanged( const QModelIndex &index )
 {
   QVariant data = index.data ( Qt::EditRole );
   if ( ! data.isNull() )
   {
     QTidy::QTidyNodeRole tnr = data.value<QTidy::QTidyNodeRole>();
     QDomNode nNode = tnr.node;
     qDebug() << nNode.nodeName() << nNode.parentNode().nodeName();
   }
 }

data

)

set Document Content e.g. html/xml Document.

Insert XML/HTML into Data model. If Document isValid() and Wellformed then it returns TRUE otherwise FALSE.

Note:

QDomDocument can not load broken Documents!

data

html/xml Dataset

QDomDocument QTidy::QTidyXHtmlTree::getDocument

(

)

const

Current Document.

const QDomNode QTidy::QTidyXHtmlTree::nodeByTagName

(

const QString &

nodeName = QString::fromUtf8("html")

)

find firstChildNodes by NodeName

Parameters:

nodeName

Optional firstChild NodeNames (html|head|body)

QAbstractItemModel* QTidy::QTidyXHtmlTree::model

(

const QString &

sibling = QString::null

)

Load ItemModel for DomTreeView.

Load Document into QAbstractItemModel and generate QListTreeModel

Parameters:

sibling

Optional Siblings (html|head|body)

void QTidy::QTidyXHtmlTree::errorMessage	(	const QString &	mess,
		int	line,
		int	row
	)			[signal]

This Signal ist emitted when QDomDocument::setContent fails
