QT Creator defining exceptions

Question

I want to define a simple exception but when I do this Im getting an error saying "expected class name"

#include <exception>
class MyException : public exception{
    
};

This is in a QT (https://www.qt.io/) widget application. Wont let me inherit from exception, why is this?

Answer 1

#include <exception>

class MyException : public std::exception{
    
};
