Unfortunately I only get GtkEntry :-(

I've checked that the first argument to gtk_container_forall() is a 
GtkComboBoxEntry
And according to printout from the callback it has only one child which 
in an GtkEntry.

According to the documentation on my machine it should be 2.4.13 I have 
on my FC3 - this is really strange!

The test you ran was that on a 2.4.13 or 2.5.5 or both?

Thanks for the explanation.

I think these six macros should also be in the reference manual.
I expect to be able to find any (public) available function/macro in the 
reference manual.

I checked in the reference manual before use - and know the difference! 
But thanks for pointing it out.
