Using QMetaObject::invokeMethod() doesn't work

[bruccutler]

I'm trying to make my first QMetaObject::invokeMethod() call, but it doesn't work.

Here is what I'm doing:

int main(int argc, char *argv[])
{
  QApplication app(argc, argv);
 
  MainProcess *p = new MainProcess();
  p->slotStart();
  bool bValue = QMetaObject::invokeMethod(p, "slotStart", Qt::DirectConnection); // QueuedConnection);
 
  return app.exec();
}

int main(int argc, char *argv[])
{
  QApplication app(argc, argv);

  MainProcess *p = new MainProcess();
  p->slotStart();
  bool bValue = QMetaObject::invokeMethod(p, "slotStart", Qt::DirectConnection); // QueuedConnection);

  return app.exec();
}

To copy to clipboard, switch view to plain text mode 

The p->slotStart() calls the method just fine, but the invokeMethod() returns false.

Any ideas?

Any ideas?

Let's start with the simple ones:

• slotStart is actually a slot?
• MainProcess is a QObject?
• MainProcess contains the Q_OBJECT macro?

If you can answer all these questions with yes, we might have to digg deeper ;-)

No - slotStart was not a slot. I had forgotten to include Q_OBJECT in the header file. Oops - I've done that too many times when I create a new class.

Thanks for your help.
