  17.     {
  18.         ui.setupUi(this);
  19.         installEventFilter(ui.sprache_cb->view());
  20.  
  21.         connect(ui.actionverbinden, SIGNAL(triggered()), this, SLOT(verbinden()));
  22.         connect(ui.speichern_btn, SIGNAL(clicked()), this, SLOT(selectSprache()));
  23.     }
  24.  
  25. bool MainWindow::verbinden()
  26. {
  27. 	 	QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
  28.         db.setHostName("pcpsr5");
  29.         db.setDatabaseName("DRIVER={SQL Server};SERVER=pcpsr5;DATABASE=inventar;UID=sa;PWD=");
  30.         db.setUserName("sa");
  31.         db.setPassword("");
  32.         if(!db.open())
  33.         {
  34.     	QMessageBox::information(this,"",db.lastError().text());
  35.         return false;

  50. 	QMessageBox::information(this,"","");
  51. }
  52.  
  53. bool MainWindow::eventFilter( QObject *o, QEvent *e )    
  54. {
