I found the problem

Was:

Qt Code:
  1. const QString Attr::FILE_NAME_LABEL = tr( "File name: " );
  2. .....
  3.  
  4. Attr::Attr( QWidget* const in_parent, const QString& in_dir, const ViewTable::SelectedItems& in_items )
  5. : QDialog( in_parent )
  6. .....
  7. , d_fname_label ( new QLabel( FILE_NAME_LABEL , this ) )
  8. {
  9. }
To copy to clipboard, switch view to plain text mode 

And now:
Qt Code:
  1. , d_fname_label ( new QLabel( tr( FILE_NAME_LABEL ), this ) )
To copy to clipboard, switch view to plain text mode 

In initialisation in constructor must be 'tr' !!!!!!

Best Regards
