How to make instant informing about the loss of connection with the SQL server in QT?

Hello! It seems that the connection to the SQL server is clear.
But now there is a problem about warning the user about connection loss in real time. Can you suggest how to do it culturally.
For example, if the connection has dropped, then immediately display a message in the form of a dialog box to the user.
