How to browse folders in C++ or C?

Question

I am implementing a program in C (also in C++) to sort files using threads, I need to implement a GUI in C++ or C to select the file to sort, without indicating the path through input standard (a equivalent of JFileChooser in Java). What tutorials do you recommend? I was reading about Qt but I'm not very familiar with this IDE. If you have any example would help me a lot.

Answer 1

Very simple with QT:

 void openFile()
  {
    QFileDialog::getOpenFileName( this, tr("Open Document"), QDir::currentPath(), tr("Document files (*.doc *.rtf);;All files (*.*)"), 0, QFileDialog::DontUseNativeDialog );

    QString filename = QFileDialog::getOpenFileName( 
        this, 
        tr("Open Document"), 
        QDir::currentPath(), 
        tr("Document files (*.doc *.rtf);;All files (*.*)") );
    if( !filename.isNull() )
    {
      qDebug( filename.toAscii() );
    }
  }
