how to list out all files in a dir and sub dir

[rajesh]

Hi!
I have written following code to find all files in given directories, but the following code does not give the list of all files available in sub directory too.
How to get all file names?
And how to filter only specific extension files eg: only .txt file ?

QDir dir(wsPath);
dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks);
QFileInfoList list = dir.entryInfoList();
for (int i = 0; i < list.size(); ++i) 
{
   if(list.at(i).completeSuffix() == "txt" )
   {
 
   }
}

QDir dir(wsPath);
dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks);
QFileInfoList list = dir.entryInfoList();
for (int i = 0; i < list.size(); ++i) 
{
   if(list.at(i).completeSuffix() == "txt" )
   {
 
   }
}

To copy to clipboard, switch view to plain text mode

How about:

QDir dir(wsPath);
foreach( const QFileInfo& entry, dir.entryInfoList( QStringList() << "*.txt", QDir::Files | QDir::Hidden | QDir::NoSymLinks ) ) {
   //...
}

QDir dir(wsPath);
foreach( const QFileInfo& entry, dir.entryInfoList( QStringList() << "*.txt", QDir::Files | QDir::Hidden | QDir::NoSymLinks ) ) {
   //...
}

Thanks Jacek,


Your code solved only 2nd requirement. But my basic requirement is how to get subdirectories file?

QString nameFilter( "*.txt" );
QDir::Filter filter = QDir::AllDirs | QDir::NoDotAndDotDot | QDir::Hidden | QDir::NoSymLinks;
 
push dir
while not empty:
   pop dir
   foreach( const QFileInfo& entry, dir.entryInfoList( nameFilter, filter ) ) {
      if( entry.isDir() ) {
         push entry.dir();
      }
      else {
         // ...
      }
   }
}

QString nameFilter( "*.txt" );
QDir::Filter filter = QDir::AllDirs | QDir::NoDotAndDotDot | QDir::Hidden | QDir::NoSymLinks;

push dir
while not empty:
   pop dir
   foreach( const QFileInfo& entry, dir.entryInfoList( nameFilter, filter ) ) {
      if( entry.isDir() ) {
         push entry.dir();
      }
      else {
         // ...
      }
   }
}
