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();
...
}
