  2. {
  3.     QString fileName = serverDir->currentItem()->text(0);
  4.     if( currentServerDir[ fileName ] )
  5.     {
  6.         QMessageBox::information(this, tr("Client FTP"), tr("Vous devez selectionner un fichier source\n %1 est un dossier") .arg(fileName));
  7.         return;
  8.     }    
  9.  
  10.     QDirModel *dirMod = (QDirModel *)(localDir->model());
  11.     bool selectedIsDir = dirMod->fileInfo( localDir->currentIndex() ).isDir();
  12.     QString path = dirMod->fileInfo( localDir->currentIndex() ).absoluteFilePath();
  13.  
  14.     if(selectedIsDir)
  15.     {
  16.         QFile *file = new QFile(path + "/" + fileName);
  17.  
  18.  
  19.         if ( QFile::exists(path + "/" + fileName) )
  20.         {
  21.             QMessageBox  msgBox(QMessageBox::Warning, "FTP Erreur", "Le fichier " + fileName + " existe deja\nVoulez vous le remplacer ?", QMessageBox::Yes | QMessageBox::No, this);
  22.             switch ( msgBox.exec() ) 
  23.             {
  24.                 case QMessageBox::Yes:
  25.                     break;
  26.                 case QMessageBox::No:
  27.                     return;
  28.                     break;
  29.                 default:
  30.                     return;
  31.                     break;
  32.             }
  33.         }
  34.         if (!file->open(QIODevice::WriteOnly)) {
  35.             QMessageBox::information(this, tr("Client FTP"), tr("Impossible d'enregistrer le fichier %1: %2.") .arg(fileName).arg(file->errorString()));
  36.             delete file;
  37.             return;
  38.         }    
  39.  
  40.         ftp->get(fileName, file);
  41.         stopAction->setEnabled(true);
  42.         down=new MyTreeWidgetItem;
  43.         currentDown[ ftp->currentId() ] = down;
  44.         connect( ftp, SIGNAL( dataTransferProgress(qint64, qint64) ),  currentDown[ ftp->currentId() ] , SLOT( progressTranferDataSlot(qint64, qint64) ) );
  45.         listDown->addTopLevelItem( currentDown[ ftp->currentId() ] );
  46.         currentDown[ ftp->currentId() ]->setLine(1, fileName);
  47.  
  48.         dirMod->refresh();
  49.     }
  50.     else
  51.     {
