hello i am using the following program to display the qtreewidget.

main.cpp

include

include "qdomsimple.h"

include

include "qdomsimple.h"

int main(int argc, char *argv[]) { QApplication a(argc, argv); QStringList filelist; filelist.push_back("C:\department1.xml"); filelist.push_back("C:\department2.xml"); filelist.push_back("C:\department3.xml"); QDOMSimple w(filelist); w.resize(260,200); w.show(); return a.exec(); }

qdomsimple.cpp

include "qdomsimple.h"

include

include

QDOMSimple::QDOMSimple(QStringList strlst,QWidget *parent) : QWidget(parent) { k=0; // DOM document QDomDocument doc("title"); QStringList headerlabels; headerlabels.push_back("Chemistry"); headerlabels.push_back("Mechanical"); headerlabels.push_back("IT");

m_tree = new QTreeWidget( this );
m_tree->setColumnCount(3);
m_tree->setHeaderLabels(headerlabels);

QStringList::iterator it;

for(it=strlst.begin();it<strlst.end();it++)
{
QFile file(*it);
if ( file.open( QIODevice::ReadOnly | QIODevice::Text ))
{
    // The tree view to be filled with xml data
    // (m_tree is a class member variable)

    // Creating the DOM tree
    doc.setContent( &file );
    file.close();
    // Root of the document
    QDomElement root = doc.documentElement();
    // Taking the first child node of the root
    QDomNode child = root.firstChild();
    // Setting the root as the header of the tree
    //QTreeWidgetItem* header = new QTreeWidgetItem;
    //header->setText(k,root.nodeName());
    //m_tree->setHeaderItem(header);

    // Parse until the end of document
    while (!child.isNull())
    {
        //Convert a DOM node to DOM element
        QDomElement element = child.toElement();
        //Parse only if the node is a really an element
         if (!element.isNull())
        {
            //Parse the element recursively               
            parseElement( element,0);
            //Go to the next sibling
            child = child.nextSiblingElement();
        }
    }
    //m_tree->setGeometry( QApplication::desktop()->availableGeometry() );
    //setGeometry( QApplication::desktop()->availableGeometry() );
}
k++;

} }

void QDOMSimple::parseElement( QDomElement& aElement, QTreeWidgetItem *aParentItem ) { // A map of all attributes of an element QDomNamedNodeMap attrMap = aElement.attributes(); // List all attributes QStringList attrList;

for ( int i = 0; i < attrMap.count(); i++ )
{
    // Attribute name
  //QString attr = attrMap.item( i ).nodeName();
    //attr.append( "-" );
   /*  Attribute value
    QString attr;
    attr.append( attrMap.item( i ).nodeValue() );*/
    //attrList.append( attr );
    attrList.append(attrMap.item( i).nodeValue());
 }

QTreeWidgetItem* item;
// Create a new view item for elements having child nodes
if (aParentItem)
{
    item = new QTreeWidgetItem(aParentItem);
}
// Create a new view item for elements without child nodes
else
{
    item = new QTreeWidgetItem( m_tree );
}

//Set tag name and the text
QString tagNText;
tagNText.append( aElement.tagName() );
//tagNText.append( "------" );
//tagNText.append( aElement.text() );
item->setText(0, tagNText );
// Append attributes to the element node of the tree

for ( int i = 0; i < attrList.count(); i++ )
{
    QTreeWidgetItem* attrItem = new QTreeWidgetItem( item );
    attrItem->setText(0, attrList[i] );
}

// Repeat the process recursively for child elements
QDomElement child = aElement.firstChildElement();
while (!child.isNull())
{
    parseElement( child, item );
    child = child.nextSiblingElement();
}

} QDOMSimple::~QDOMSimple() {

}

for this i got the qtreewidget like this

+file1 +file2 +file3

but actual wanted output is +file1 +file2 +file3

i don't know how to do it.Thanks in advance
