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.

Qt Code: 
  1. while (qdirIterator.hasNext())
  2.  
  3.     {
  4.         QString fileName = qdirIterator.next();
  5.         QFileInfo fileInfo = qdirIterator.fileInfo();
  6.  
  7.         QFile inFile( fileInfo.absoluteFilePath() );
  8.  
  9.         if( !inFile.open( QIODevice::ReadOnly | QIODevice::Text ) )
  10.         {
  11.             qCritical( "Failed to open file for reading." );
  12.             return;
  13.         }
  14.         .
  15.         .
  16.         .
  17.     } // 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:

Qt Code: 
  1. QFile inFile;
  2. while (qdirIterator.hasNext())
  3.     {
  4.         QString fileName = qdirIterator.next();
  5.         QFileInfo fileInfo = qdirIterator.fileInfo();
  6.  
  7.         if( !inFile.open( fileName, QIODevice::ReadOnly | QIODevice::Text ) )
  8.         {
  9.             qCritical( "Failed to open file for reading." );
  10.             return;
  11.         }
  12.         .
  13.         .
  14.         .
  15.         inFile.close();
  16.     } // 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.
