Is there any way to prevent firing signals under some conditions?

Is there any way to prevent firing signal under some conditions? You can use the clicked signal because it is only emitted when the user actually clicked the check box, not when you manually check it using setChecked. The downside of this approach is that all signals will be blocked. But I guess that doesn’t really matter in case of a QCheckBox.

What happens if the signal handler is not defined?

The order that the signal handlers run between processes is not defined, so you can’t rely on either executing first. If you don’t define an interrupt handler (or explicitly ignore the signal), both processes would just exit with a SIGINT code (the default behaviour).

How to prevent an object from emitting a signal?

In QObject derived classes, you can call blockSignals (bool) to prevent the object from emitting signals.

Why is it important to use bottle for retrieving information?

What to do if there is no signal handler?

If there is no signal handler, the default handler is called instead. The process tell the kernel the types of signals it is interested in to handle in a non-default way by providing handler functions (callbacks). To register a signal handler, use one of the signal API functions [2].

What happens if something goes wrong in bottle?

If anything goes wrong, Bottle displays an informative but fairly plain error page. You can override the default for a specific HTTP status code with the error () decorator: From now on, 404 File not Found errors will display a custom error page to the user. The only parameter passed to the error-handler is an instance of HTTPError.
