Re: Missing Gtk3::MessageDialog's format_secondary_text method?

[Emmanuele Bassi <ebassi gmail com>]

hi;

the gtk_message_dialog_format_secondary_text() function is not
introspectable, because it takes a variadic arguments list.

not that you'd need it in Perl, tho, since it's just a wrapper around
g_strdup_printf(), and Perl has its own string formatting tools.

if you want to set the secondary-text property, you can pass the
secondary text as a constructor property:

  $primary = sprintf $primary_format, @primary_args;
  $secondary = sprintf $secondary_format, @secondary_args;
  $message_dialog = Glib::Object::new('Gtk3::MessageDialog', text =>
$primary, secondary_text => $secondary);

or you can use the Glib::Object::tie_property() function function to
automatically tie properties to values keys in the instance hash,
e.g.:

  $message_dialog->tie_properties;
  $message_dialog->{secondary_text} = sprintf 'foo %d', $value; #
shows the secondary text label
  $message_dialog->{secondary_text} = undef; # hides the secondary text label

as a side note: I'm a bit sad that we still need the overrides for the
constructors in Gtk3 just for porting reasons; I would actually make
them opt-in, and do what Python and JavaScript do for constructors —
i.e. just call Glib::Object::new with a bunch of property key/value
pairs. I understand that it makes porting from Gtk2 to Gtk3 mildly
easier, but it creates a disconnect with the other high level
languages, and it makes some functionality harder to implement.

ciao,
 Emmanuele.
