Just a small nitpick, you are missing introspection comments
in the 'greetee' property:
/**
* TutGreeter:greetee:
*
* The entity to greet.
*/
obj_properties[PROP_GREETEE] =
....
Without comments on properties (and signals), then it becomes impossible
to tell certain things about these entities, such as the ABI version
in which they
are introduced, and whether they are deprecated (this information can be useful
for compilers who wish to implement 'greeter.greetee = greetee' using
g_object_set(),
so they can warn about use of deprecated properties, or fire runtime errors if
the runtime C library is not as new as the C library which the calling
application
was compiled for).
Not to mention, it becomes impossible for us to know the version in which
a property was installed in Glade.
While this introspection comment might not be relevant to your tutorial per se,
if we publish this then we will be setting a trend, and it would be nice to set
the trend of complete introspection comments (not to get lazy when it comes
to commenting on properties and signals, which are also a part of the API).
Cheers,
