QString text;
 text=lineEdit1->text();
 label->setText(text);

QString text;
 text=lineEdit1->text();
 label->setText(text);

To copy to clipboard, switch view to plain text mode

add two method to your dialog like these

class MyDialog: public QDialog
{
...
public:
...
    QString login() const;
    QString password() const;
...
private:
    QLineEdit *m_leLogin;
    QLineEdit *m_lePassword;
...
};
...
QString MyDialog::login() const
{
   return m_leLogin->text();
}
 
QString MyDialog::password() const
{
   return m_lePassword->text();
}
...
void MyMainWindow::showLoginDialog()
{
    MyDialog md(this);
    if (!md.exec())
       return;
   const QString login = md.login();
   const QString pasword = md.password();
  ...
}

class MyDialog: public QDialog
{
...
public:
...
    QString login() const;
    QString password() const;
...
private:
    QLineEdit *m_leLogin;
    QLineEdit *m_lePassword;
...
};
...
QString MyDialog::login() const
{
   return m_leLogin->text();
}

QString MyDialog::password() const
{
   return m_lePassword->text();
}
...
void MyMainWindow::showLoginDialog()
{
    MyDialog md(this);
    if (!md.exec())
       return;
   const QString login = md.login();
   const QString pasword = md.password();
  ...
}
