------- Comment #8 from Murray Cumming  2005-12-19 09:25 UTC -------
I've finally had the chance to look at the patch. It looks pretty good, a=
nd
seems to work.

In summary, it lets you do this:

class HelloDialog : public Gnome::Glade::Derived<Gtk::Dialog>
{
public
  HelloDialog()
  : Gnome::Glade::Derived<Gtk::Dialog>("derivedclass.glade", "exampleDial=
og")
  {}
};

or

class HelloButton : public Gnome::Glade::Derived<Gtk::Button>
{
public
  HelloDialog(const Glib::RefPtr<Gnome::Glade::Xml>& xml)
  : Gnome::Glade::Derived<Gtk::Dialog>(xml, "exampleButton")
  {}
};

However, in almost all cases you would want the constructor to take a
Glade::Xml, so you can do this:

class HelloDialog : public Gnome::Glade::Derived<Gtk::Dialog>
{
public
  HelloDialog()
  : Gnome::Glade::Derived<Gtk::Dialog>("derivedclass.glade", "exampleDial=
og"),
    m_button(get_xml(), "button")
  {}
};

So the only advantage to this method that I see is that it requires less =
code,
and can be used in the initializer list. That's good though.

However,=20
1. it uses the SomeWidget(cobject) constructor directly, without checking
whether there is an existing instance that it should return (See
ObjectBase::_get_current_wrapper() in the existing get_widget_derived()),=
 so
this would cause problems if two widgets were instantiated for the same i=
tem in
the glade file.
2. It doesn't check whether the instantiated C widget is of the expected =
type.
But that should be easy to add.

------- Comment #3 from Murray Cumming  2005-12-19 09:32 UTC -------
Thanks. Sorry for the delay.

So, get_widget_derived() takes a slot and calls to instantiate the widget=
, so
that the widget's constructor can have the Glade::Xml parameter at any po=
sition
in the parameter list. However, derived widgets would still need/want to =
take
the Glade::Xml parameter in their constructor.

When would this be helpful?

I suggest that you contact the gnome-doc people on one of their mailing l=
ists
if you need help. This should be a fairly generic GNOME documentation sys=
tem
issue.

------- Comment #3 from Murray Cumming  2005-12-19 09:42 UTC -------
This is fantastic.

I suggest avoiding stuff such as "Because Gdk is older and more mature th=
an
Cairo, it tends to be somewhat faster and more efficient at the moment.",
because it will become outdated very quickly. Instead, I suggest recommen=
ding
the new methods wherever possible, and only mention Gdk where there is no
alternative and/or it's really meant to still be used together with Cairo=
. Put
the historical stuff in an appendix if you think it's really necessary.

Please avoid using gint in gtkmm examples - We only use g types where the=
y
offer some platform independence. And I'd prefer "event" to "e".

We might need to update this slightly if I apply this patch:

Good points.  I'll make the changes you've mentioned. =20

Have you made a decision about whether you'll apply that RefPtr patch or =
not?=20
The email sounded like you're leaning toward it.  If this bug is still op=
en
when you make a decision, will you add a comment here so I'm sure to catc=
h it?
(although I suppose compilation of the examples will fail when I update m=
y
working directory, so I'll almost certainly notice)

I also just realized that all of my screenshots use the clearlooks theme.=
=20
Since this is the new default theme for GNOME (right?) it seems like the =
thing
to do, but it doesn't match the existing screenshots.  Any thoughts on th=
at?

Another question: I've used some of the 'tip' or 'note' docbook elements
because I find them useful for mentioning things that are related but don=
't
flow as well within the text.  I've noticed that the existing tutorial do=
esn't
make use of these elements -- was it an intentional decision to avoid the=
m?

Also, in the examples, I've used the C enum values (e.g. CAIRO_LINE_CAP_R=
OUND).
 Is this the intended way to use these, or will there be wrapped enum typ=
es
within the Cairo namespace in the future (or are there already?) such as
Cairo::LINE_CAP_ROUND or something similar?

I apologize for the extra crap (dotfiles, etc) that was accidentally incl=
uded
in the tarball of new files.  I'll post an updated one when I make the ch=
anges
above.

I probably will apply it, but I'm waiting for people to object. Do you mi=
nd it?

You might want to wait a day or two.

> clearlooks theme

Yes, that's OK. Some time we must update all the screenshots.

> 'tip' or 'note' docbook elements

I didn't know about them. Feel free.

> will there be wrapped enum types within the Cairo namespace in the futu=
re

Yes, I think so, though it will require copy/pasting.
