Preprocessor macro and Q_INVOKABLE

 

I need to declare Q_INVOKABLE method inside a preprocessor macro.
Is it possible? Looks like it does not work.

Thank you,
Michael

No, that is not possible. Q_INVOKABLE is processed by moc, which does not expand macros itself and is run before macros are expanded.

The same is true for many other Q_* “macros”. They actually expand to nothing in the preprocessor. They are special keywords used by the meta-object compiler to indicate that it needs to generate some code there.
