Your MyDialog should have a UI file and a UI class. You should add a public getter function to MyDialog that gets the text of the line edit of the UI class. It is not recommended that you expose internals of the implementation of a class in this way. So, your getter should look like:
QString MyDialog::someText() const { return m_ui->lineEdit->text(); }
