how to recursive a directory in qt?

[deweyjew]

i use qt/e2.3.10, my code is below, but it doesn't work, why?

int addFileFromDir(const QString& d)
{
	QDir dir( d );
	dir.setMatchAllDirs( true );
	dir.setSorting(QDir::DirsFirst | QDir::IgnoreCase);
	if( !dir.exists() )
	{
		return -1;
	}
	QString file;
	const QFileInfoList * list = dir.entryInfoList();
	if( list )
	{
		QFileInfoListIterator it(*list);
		QFileInfo *fi;
		while ( (fi = it.current()) != 0 )
		{
			qDebug( fi->absFilePath() );
			if ( !fi->isDir() )
			{
				//do something
			} 
			else if ( fi->isDir() && (fi->fileName()!=".") && (fi->fileName()!="..") ) 
			{
				addFileFromDir( fi->absFilePath() );
			}
			++it;
		}
	}
	return 0;
}

int addFileFromDir(const QString& d)
{
	QDir dir( d );
	dir.setMatchAllDirs( true );
	dir.setSorting(QDir::DirsFirst | QDir::IgnoreCase);
	if( !dir.exists() )
	{
		return -1;
	}
	QString file;
	const QFileInfoList * list = dir.entryInfoList();
	if( list )
	{
		QFileInfoListIterator it(*list);
		QFileInfo *fi;
		while ( (fi = it.current()) != 0 )
		{
			qDebug( fi->absFilePath() );
			if ( !fi->isDir() )
			{
				//do something
			} 
			else if ( fi->isDir() && (fi->fileName()!=".") && (fi->fileName()!="..") ) 
			{
				addFileFromDir( fi->absFilePath() );
			}
			++it;
		}
	}
	return 0;
}
