Well, I was confused by that Note (and probably therefore initially ignored
it), because I thought I was looking at the documentation for the gtkmm
library, version 2.4, not 2.10.  After all, the URL always has
.../gtkmm-2.4/... in it.  I didn't see what version 2.10 had to do with
anything.

After messing around with gtkmm and the website for a while, I think I finally
understand that two different version numbers are involved: the API version,
and the library version.  The distinction was not initially clear to this
newbie, however.  (I'm not a programming newbie, but more of a newbie to open
source programming libraries, and definitely to GTK, gtkmm, etc.)

While it does say "This documentation is for the gtkmm 2.4 and gnomemm 2.6
APIs." at the top of http://www.gtkmm.org/docs/gtkmm-2.4/docs/, perhaps it
should *also* say something like:

"This means any version of the gtkmm library 2.4 through 2.10."  (or whatever
version numbers)

Or maybe:

"If you are using a version of the gtkmm library below 2.10, these docs may not
apply to you."

Whichever is the case.


Also, in the tutorial, perhaps another disclaimer like:

"Some chapters of the tutorial may apply to all versions of the gtkmm library,
from 2.4 through 2.10, while some may apply only to newer versions of the
library.  Please also see the tutorial accompanying your version of the gtkmm
library for information more specific to you."

And perhaps each chapter or section could indicate specifically which library
versions should work with it.  At least this would give more of a heads-up to
newbies (who I would expect to be looking at the tutorial) that what they are
looking at may not apply to their situation.


As for that note in Chapter 15, I notice that the appendix it refers to appears
to be missing a lot of information about GDK that is in Chapter 14 of the
tutorial I have installed locally (somewhat analogous to Chapter 15 of the
online tutorial).  Why not keep those extra sections in that appendix for
people with older versions of the gtkmm library?


I hope this helps in some small way.

------- Comment #5 from Hans Breuer  2006-06-05 17:47 UTC -------
Given that The GIMP people have written a bunch of code to have the
accelerators back in their "context menus" - and given that Dia now also uses
GtkUIManager and
thus has to either lack the accelerators or cut and paste a lof of code to
resurrect them:
Could there please be some function in Gtk to reenable the accelerators in 
nested "context menus"? They may be bad from the HIG's point of view, but
IMO the toolkit should not enforce the HIG - just make it possible and
convenient to follow. And to violate it where appropriate.
