Missing items in loadFile

Hello anyone,

I want to load my contact.txt in the function loadFile.
In my contact.txt i have seperated the items through tab.
When open the file for reading he display only in QTreeWidget 4 items
example:
Drabo Hardenberg Dhr. J. Tuik 0523-678905.

See code loadFile

Code:

---

void MainWindow::loadFile(const QString &fileName)
{
	QFile file( fileName );
	if( !file.open(QFile::ReadOnly))
	  return;
 
		QTextStream in( &file);
		QString line;
		QTreeWidgetItem *item = new QTreeWidgetItem( contactView );
 
                        do  {
 
				line = in.readLine();
				if(!line.isEmpty())
				{
				QStringList contact = line.split('\t', QString::SkipEmptyParts);
				QStringList::Iterator it = contact.begin();
				if(it != contact.end())
				{
					item->setText(0, (*it));
					++it;
				}
				if(it != contact.end())
				{
					item->setText(1, (*it));
					++it;
				}
				if(it != contact.end())
				{
					item->setText(2, (*it));
					++it;
				}
				if(it != contact.end())
				{
					item->setText(3, (*it));
					++it;
				}
			    }
 
		}while(!line.isEmpty());
 
	file.close();
 
}

Is there something missing in the code

Here is my code for the saveFile

Code:

---

void MainWindow::saveFile(const QString &fileName)
{
 
	QFile file( fileName );
	if ( !file.open(QFile::WriteOnly))
	  return;
 
	QTextStream out( &file );
 
	int ind = 0;
	while(QTreeWidgetItem *item = contactView->topLevelItem(ind))  {
		for ( unsigned int i = 0; i < 4; i++ )
     		 out << item->text(i) << '\t';	
		out << '\n';
	ind ++;
	}
	file.close();
 
}

Hi,

What is the exact problem...you want to display all the Items (If I count well, there are 6 "items" in the example you gave... ?

Guilugi.

seems like you only save 4 items to your file.

Code:

---

for ( unsigned int i = 0; i < 4; i++ )

---

what is in your file after using safeFile? All the fields or just 4 of them?

cheers

In my contact.txt there are 4 items on each line seperate with a tab
example of my contact.txt.

When i load the contact.txt the QTreeWidget display 1 line with items and not 3 lines.

Ok,

The fact is you create only one TreeWidgetItem!
You have to put your line in the loop, like this :

Code:

---

void MainWindow::loadFile(const QString &fileName)
      {
          QFile file( fileName );
          if( !file.open(QFile::ReadOnly))
            return;
              QTextStream in( &file);
              QString line;
                              do  {
                      line = in.readLine();
                      if(!line.isEmpty())
                      {
                       QTreeWidgetItem *item = new QTreeWidgetItem( contactView );
 
                      QStringList contact = line.split('\t', QString::SkipEmptyParts);
                      ....

This should work better :)

Guilugi.

you could try :
!in.atEnd()}
instead of
!line.isEmpty());

Thanks guilugi for your answer and time it works fine now.
Everall i have also tested your sugestion but it didn't work.
Thanks also for your sugestion.
Bye
