Qdoc - conditional generation

[skypjack]

Hi all,
I would like to know if it's possibile to have a conditional generation with qdoc.
I've tried as follows, but it doesn't work.

@
#if defined(COND_VAR)
/*!
Something happens.
/
#else
/!
Nothing happens.
*/
#endif
@

The condition variable, COND_VAR, has been defined as usual using the macro define.
I've had this problem by reviewing the documentation of Qt5.
Unfortunately, each part has been parsed by qdoc.

Any suggestions?
Thanks.
