Program in Qtopia 2.2.0 with QT2 designer

Hi guys,

I built a file browser application using QListView and QDir classes. I drew
 a listview on UI with the help of QT2 designer...
 My implementation file is as follows...

#include "filebrowser.h"//my header file
#include <qdir.h>
#include <qlistview.h>
#include <qstringlist.h>

QDir dir=QDir::rootDirPath();
QFileDialog *f
FileBrowser::FileBrowser(QWidget *parent,const char *name,WFlags fl):
FileBrowserForm(parent,name,fl)
{
   if(dir.exists())
   {
      if(dir.isReadable())
      { 
      MyListView->clear();
      QStringList dirList(dir.entryList());
      for(QStringList::Iterator it=dirList.begin();it!=dirList.end();it++)
      {
         QListViewItem *dirItem=new QListViewItem(MyListView);
         dirItem->setText(0,(*it));
         MyListView->insertItem(dirItem);
      }
      }
   }

  
connect(MyListView,SIGNAL(doubleClicked(QListViewItem*),this,SLOT(setDir(QListVi
ewItem*)));
connect(UpButton,SIGNAL(clicked()),this,SLOT(upPath());
}

void FileBrowser::setDir(QListViewItem *item)
{
   if(dir.cd(item->text(0),true)
   {
     if(dir.exists())
     {
       if(dir.isReadable())
       {
       MyListView->clear();
       QStringList dirList(dir.entryList());
       for(QStringList::Iterator it=dirList.begin();it!=dirList.end();it++)
       {
         QListViewItem *dirItem=new QListViewItem(MyListView);
         dirItem->setText(0,(*it));
         MyListView->insertItem(dirItem);
       }
       }
     }
   }
}

void FileBrowser::upPath()
{
   if(dir.cdUp())
   {
     if(dir.exists())
     {
      if(dir.isReadable())
       {
       MyListView->clear();
       QStringList dirList(dir.entryList());
       for(QStringList::Iterator it=dirList.begin();it!=dirList.end();it++)
       {
         QListViewItem *dirItem=new QListViewItem(MyListView);
         dirItem->setText(0,(*it));
         MyListView->insertItem(dirItem);
       }
       }
     }
   }
}
   
This code compiles fine,but gives runtime errors as 
Line.17....5849..aborted
