DisplayTree Structure of the path

Hi all

Here there is a pr[B]ogram which is copying source to destination but by using this logic i want it displays all the items of the selectedpath in a tree structured form.
Code:
#include <qfiledialog.h> 
#include <qstring.h> 
#include<qlabel.h>
#include<qstringlist.h>
#include<qprogressbar.h>
#include<qfile.h>
#include<qdir.h>
#include<stdio.h>
#include <qfileinfo.h> 
#include<qmessagebox.h>
#include <qapplication.h>
 
void Form1::init()
{
   m_totalsteps= 1;
  progress->setTotalSteps(4000);
 
}
 
void Form1::copydata()
{
CopyAllFilesandFolders(m_StrSource,m_StrDestination);
 
}
 
void Form1::CopyAllFilesandFolders(QString source,QString destination)
{
    QDir dir(source);
    QDir dir1;
    QString sourceFilePath;
   const QFileInfoList * dirs=dir.entryInfoList();
    {
	if(dirs)
 
  {   
	    QFileInfoListIterator it(*dirs);
	    QFileInfo * fileInfo;
	   while(fileInfo=it.current())
	    {
		++it;
 
		if(fileInfo->fileName() =="." || fileInfo->fileName() =="..")
		    ;
		else if(fileInfo->isDir())
		{
		    QString destinationFilePath;
		    destinationFilePath = destination + ("/") + fileInfo->fileName();
		    dir1.mkdir(destinationFilePath,true);
                                sourceFilePath = source + ("/") + fileInfo->fileName();
		   CopyAllFilesandFolders(sourceFilePath,destinationFilePath);
		   copy->setText(sourceFilePath);
 
		   }
 
		else
		{
		    QString destinationFilePath;
		    destinationFilePath = destination+("/")+fileInfo->fileName();
		    sourceFilePath = source+("/")+fileInfo->fileName();
		    CopyFiles(sourceFilePath,destinationFilePath);
		    copy->setText(sourceFilePath);
		  }
 
 
		  ReadNextDir();
	    } 
 
 
 
       }
 
 
 
   }
 
 
 
}
 
 
bool Form1::CopyFiles(QString sourceFilePath,QString destinationFilePath)
{
    bool  success=false;
    QFile srcFile(sourceFilePath);
    QFile destFile(destinationFilePath);
    uint  dataLength=4096;
    char*data = new char[dataLength];
    if(srcFile.open(IO_ReadOnly))
    {
	if(destFile.open(IO_WriteOnly))
	{
	    while(!srcFile.atEnd())
	    {
		memset(data,0*00,dataLength);
		int iTotalByteRead=srcFile.readBlock(data,dataLength);
		destFile.writeBlock(data,iTotalByteRead);
	    }
	    delete data;
	    destFile.close();
	    success=true;
	}
	srcFile.close();
    }
    return success;
}
 
void Form1::SetSource()
{
 m_StrSource = QFileDialog::getExistingDirectory(
                    "/home",
                    this,
                    "get existing directory",
                    "Choose a directory",
                    TRUE );
 
 source->setText(m_StrSource);
}
 
void Form1::SetDestination()
{
m_StrDestination = QFileDialog::getExistingDirectory(
                    "/home",
                    this,
                    "get existing directory",
                    "Choose a directory",
                    TRUE );
 destination->setText(m_StrDestination);
}
 
void Form1::ReadNextDir()
{  
      QApplication * qApp;
      qApp->processEvents();
     progress->setProgress(++m_totalsteps);
 
  }
Thanx in advance
