qInstallMessageHandler() add object method. How?

[bogong]

Hello!
Is there any way to add to qInstallMessageHandler() NOT static function but object method?
Something like this:

ObjectType* oObject = new ObjectType();
qInstallMessageHandler(oObject->objectMethod());

I know how to use static method:

class Class {
  static void  messageHandler(QtMsgType, const QMessageLogContext &, const QString &);
};

...
qInstallMessageHandler(Class::messageHandler);
...

The question is about calling from object.

To answer your question directly, you should be able to go one of:

qInstallMessageHandler(oObject->objectMethod);
qInstallMessageHandler(&oObject->objectMethod);

But it's not a very good idea! Because if oObject goes away your global message handler is left pointing to a method of a non-existent object....

Solution found. Issue closed. Example is here.

Having glanced through that, I see it goes

qInstallMessageHandler(ALogger::mWriteToLog);

Which is a static function, exactly what you said you did not want!

Note that it does not go

qInstallMessageHandler(oLogger->mWriteToLog);
