Just got this error message while compiling a tiny class that derives from
error C2039: 'staticMetaObject' : is not a member of 'QTreeWidgetItem'
What this is saying is that
QTreeWidgetItem does not inherit from
QObject, meaning that your own, singly-inherited class also does not inherit from
QObject. Inheriting from
QObject is one of the prerequisites to using the
Q_OBJECT macro, which, if you're anything like me, you automatically insert into any Qt GUI related class.
If you're not using any of the meta object stuff in your subclass, such as signals/slots or properties, just take out the
Q_OBJECT macro. If you need to use signals and slots, you'll need to make your subclass multiply-inherit from
QObject as well. If you take this route, remember that "Multiple Inheritance Requires QObject to Be First", otherwise you'll get either the same error as above, or something along the lines of "
YourClass inherits from two QObject subclasses" from the moc.
