Creating QFile Objects in a loop

[sky]

Hi All,

I have a quick question:

I have a dir which has a huge number of files in it. I need to iterate through all the files and open them.

while (qdirIterator.hasNext())
 
    {
        QString fileName = qdirIterator.next();
        QFileInfo fileInfo = qdirIterator.fileInfo();
 
        QFile inFile( fileInfo.absoluteFilePath() );
 
        if( !inFile.open( QIODevice::ReadOnly | QIODevice::Text ) )
        {
            qCritical( "Failed to open file for reading." );
            return;
        }
        .
        .
        .
    } // while

while (qdirIterator.hasNext())

    {
        QString fileName = qdirIterator.next();
        QFileInfo fileInfo = qdirIterator.fileInfo();

        QFile inFile( fileInfo.absoluteFilePath() );

        if( !inFile.open( QIODevice::ReadOnly | QIODevice::Text ) )
        {
            qCritical( "Failed to open file for reading." );
            return;
        }
        .
        .
        .
    } // while

First up when I look at this code I feel I am constructing too many QFile objects. So I want to do the following:

QFile inFile;
while (qdirIterator.hasNext())
    {
        QString fileName = qdirIterator.next();
        QFileInfo fileInfo = qdirIterator.fileInfo();
 
        if( !inFile.open( fileName, QIODevice::ReadOnly | QIODevice::Text ) )
        {
            qCritical( "Failed to open file for reading." );
            return;
        }
        .
        .
        .
        inFile.close();
    } // while

QFile inFile;
while (qdirIterator.hasNext())
    {
        QString fileName = qdirIterator.next();
        QFileInfo fileInfo = qdirIterator.fileInfo();
  
        if( !inFile.open( fileName, QIODevice::ReadOnly | QIODevice::Text ) )
        {
            qCritical( "Failed to open file for reading." );
            return;
        }
        .
        .
        .
        inFile.close();
    } // while

To copy to clipboard, switch view to plain text mode 

Problems with this are:

1. "QFile:: open" does not take QString as an argument.
2. And even if I manage to use "QFile:: open" in this manner the docs say, "When a QFile is opened using this function, close() does not actually close the file, but only flushes it."

So is there a workaround for 1. and also make sure that "QFile:: close()" actually closes the file and not just flush it?

Thanks in Advance,
sky.

You're only constructing one file at a time.
The QFile will go out of scope (destroyed) every iteration.
