[merry]

Thanx 4 the reply

But it be better if You explain it with me the help of an example or code.

Oh come on, what is there to explain?

QStringList slist = QDir("/etc/").entryList();
for(QStringListIterator it = slist.begin(); it!=slist.end(); ++it){
  new QListViewItem(*it, listview);
}

QStringList slist = QDir("/etc/").entryList();
for(QStringListIterator it = slist.begin(); it!=slist.end(); ++it){
  new QListViewItem(*it, listview);
}

Hi

I am sending u the code Please tell me its right or not for the representation of path in a tree structure form.
actually I got " segmentationfault "

Here the code is

#include <qfiledialog.h> 
#include <qapplication.h>
#include <qlistview.h>
#include <qstring.h>
#include <qfile.h>
#include <qfileinfo.h>
#include <qstringlist.h>
#include<qmessagebox.h>
#include <qpixmap.h> 
#include <qcheckbox.h> 
#include <qdir.h>
#include <qstringlist.h> 
#include <qmessagebox.h>
 
void Form1::fileOpen()
{  
 
   m_source = QFileDialog::getExistingDirectory(
                    "/",
                    this,
                    "get existing directory",
                    "Choose a directory",
                    TRUE );
   setDir(m_source);
}
 
void Form1::setDir(QString path)
{
 
	    QListViewItemIterator it(listView);
	    ++it;
	    for(;it.current();++it)
	    {
		it.current()->setOpen(FALSE);
	    }
 
 
	    QStringList slist;
	    QDir dir(path);
	    QListViewItem * item;
	    item->firstChild();
	    slist=QStringList::split("/",path);
	    slist=dir.entryList();
	    QStringList::Iterator it2=slist.begin();
	      for(;it2!=slist.end();++it2)
	    {
		while(item)
		{
		    if(item->text(0)=*it2)
		    {
			item->setOpen(TRUE);
			break;
		    }
		    item=item->itemBelow();
 
		}
 
	    }
 
	    if ( item )
               listView->setCurrentItem( item );
 
 
	}

If there is some alterations in this code then also tell me.

Thanx

Why don't you debug the code and see where it segfaults? This is only a snippet, so I can't debug it for you. Please use a debugger and print a backtrace to see where and why it crashes.

Thanx 4 ur reply and I also dont want YOU to debug for me.

Once again Thanx

Make sure you initialize all of the variables you use in Form1::setDir().
