Closing a QDialog from its Constructor in Qt

To automatically close a QDialog in a constructor, you may use the following line of code:

QMetaObject::invokeMethod(this, "close", Qt::QueuedConnection);

If you have another method of closing(not hiding) a QDialog based on a condition in its constructor, kindly share it within the comments below - thank you.
