The dialog is going to change and i don't think exposing the internals
is the best way. What we need to do is provide funcions for embeding
widgets. 

What do you want to embed from your application?

I was not the original submitter, but I would like to offer my
opinion.    

An application may have many application specific printing options
(e.g. layer selections, header and footer options, scaling options,
etc.) that may not be easily embedded into a single dialog page.  You
could argue that these go into a separate "Print setup" or "Page
setup" dialog, however this would depend on the intended scope of
these options.

If you keep the current GtkNotebook (or similar multipage paradigm), I
would be satisfied with a method to retrieve this notebook, so that I
could append or prepend pages as needed.  There should also be a
simple method of removing the paper selection page, in my application
(gLabels) it makes no sense to have this page.

If you do not keep the GtkNotebook, I would suggest keeping the
GnomePrintSelection widget public, so that print dialogs that are
appropriate for the application can be built.

Right, my intentions is to have a way of embeding widgets without
exposing the dialog, if the dialog struct is exposed we can't change
the layout without breaking the API, which is why i wanted to know in
this particular case what he wanted to add to the dialog, to see if it
is on the list that i'm planning of implementing.

For MrProject, much like gLabels, we need to have a custom notebook
page to select what views to print, or specify the time ranges to
print, etc. The easiest way to solve this kind of thing would probably
be as suggested, to make it possible to add custom pages.

You may want to have a look how gnumeric adjusts the print range
widgets to include such specs as `Active SHeet', `All', `Sheets from
to', `Selection'. 

It seems that gnome-print.h is being installed for both HEAD and gnome-2-4
