Reimplementing QApplication::notify()

[Doug Broadwell]

(C++ newbe also) I have code in my event handlers that throw errors. I would like to reimplement QApplication::notify() to be able to catch any thrown errors that I don't explicitly throw to deal with somewhat more gracefully than aborting the program.

Does anyone have an example code to do this?

Thanks,
Doug Broadwell

How about just calling the base implementation sourrounded in a try-catch block?

[Doug Broadwell]

Do you mean like:

try {
app.exec;
} catch( ... ) {
...
}

This won't work, and right now everything is event driven so I don't think there is a single place (other than app::notify()) where it could be done (???).

No, I mean:

bool MyApplication::notify(...){
try {
return QApplication::notify(...)
} catch(...){
...
}
}
