Re: gtk-perl-list Digest, Vol 57, Issue 7

funnily enough, I have been working with selections and systray/
systray icons (ie Gtk2::StatusIcon) recently, so I could definitely
have a look at the gtk_status_icon ones probably without too much
trouble at all.

Aloha,

the upcoming GNOME release 2.26 will use gtk+ 2.16 which provides new
API that we haven't wrapped in the bindings yet.  For some reason, I
seem to be unable to find the tuits to tackle this, so I'm asking
you:  Are there volunteers who are willing to help bind the new GTK+
API?

The new API is listed on 
<http://library.gnome.org/devel/gtk/2.15/api-index-2-16.html>.  New
signals and properties are automatically handled, so we don't need to
handle those.  Only new functions.  For most functions, wrapping them
consists of copying the C prototype into the relevant *.xs file and
writing a unit test for it in the corresponding *.t file.  I'd be
happy to help with the corner cases not covered by this.

No, the whole GtkBinding thing is not wrapped.  Mainly because we had
no experience using it and because we didn't know whether it would be
useful.

There don't seem to be any GTypes associated with the various
GtkBinding types, so wrappers would need to do a bit more work than
usual to convert them to and from Perl types.  There also seems to be
a lot of namespace trampling going on (function prefixes don't match
their first argument's type), so care would have to be taken in
deciding how to represent those functions in Perl land.

But maybe you just need a small subset of this API that can be
wrapped easily?

Oh, yep, not even a boxed thingie.  That's a bit unfortunate.

Ah yeah.  gtk_bindings_activate() and gtk_bindings_activate_event()
just about belongs as a GtkObject methods.  That'd be ok though would
it, nothing too evil could come from say

    $obj->bindings_activate($key,$mods)
    $obj->bindings_activate_event($event)

existing?

Yes, that'd be all I'd think to start.  by_class() to find,
add_signal() to fill defaults, then activate() on an object and/or
the bindingset itself to dispatch.  Is there more normally needed?
Ignore the strange widget_path_pspecs and other fields to start.

In fact I wonder if you set the default bindings by parsing an "RC"
string if just the object activate funcs could work, with
GtkBindingSet not wrapped at all.

Indeed those two go fine, per below.

But it seems they refuse to operate on plain GtkObjects, only widgets,
because of wanting to spin keys through the per-display keymap
thingie. So I might want gtk_bindings_set_activate() too, which would
mean wrapping GtkBindingSet, however opaquely.

I can give it a try as the weekend is arriving and it's cold outside
;) I don't have the most recent version of GTK nor perl Gtk2. I'm
using the stock versions provided by Ubuntu 7.10, which is not even
the most recent Ubuntu! I have a few questions:

What's the URL for perl Gtk2 trunk?
What's the best way for installing the newest Gtk2 and all it's
dependencies? How to keep synchronized with the other kind souls that
decided to help? Where can I submit the patches for review (mailing
list or RT)?
