[Interest] Most simple emit from singleton?

[Jérôme Godbout]

Why not declare a signals into your singleton header and call it directly?

MySingleton.h

class MySingleton
{
signals:
   void MySignals();
};

myOtherCode.cpp

Q_EMIT  MySingleton::Instance()->MySignals();

Subject: [Interest] Most simple emit from singleton?

I've stumbled across a paradigm that I am starting to use frequently where I have a singleton, and I want it to emit something when I tell it to.

So I've been providing a function and doing: MySingleton::instance()->emitMySignal();

Where:
void MySingleton::emitMySignal() {
    emit mySignal();
}

But this seems "silly". Is there a better way to do this? Ideally I'd like to skip creating the function and do something like:

MySingleton::instance()->emit MySignal(); or emit MySingleton::instance()->MySignal();


There may still be a better way?

Thoughts?

Thanks!
