connect problem

[liengen]

Hi!
Having a problem to connect a qlabel and qpushbutton.
Here`s some code:

QLineEdit *lineEdit = new QLineEdit;
  QLabel *copied = new QLabel;
  QPushButton *copy = new QPushButton("&Copy");
 
  QDialog::connect(copy, SIGNAL(clicked()), copied, SLOT(setText(lineEdit->text())));
  QDialog::connect(copy, SIGNAL(clicked()), lineEdit, SLOT(clear()));

QLineEdit *lineEdit = new QLineEdit;
  QLabel *copied = new QLabel;
  QPushButton *copy = new QPushButton("&Copy");

  QDialog::connect(copy, SIGNAL(clicked()), copied, SLOT(setText(lineEdit->text())));
  QDialog::connect(copy, SIGNAL(clicked()), lineEdit, SLOT(clear()));

To copy to clipboard, switch view to plain text mode 

The first connect sentence isnt working. I`ve tried with setText("foobar"), but even then nothing happens with the label
