Re: [xs] Bug with GtkAllocation->width

[Ross McFarland <rwmcfa1 neces com>]

in gperl_sv_from_value the following code:

g_printerr("[gperl_value_from_sv] type - %d (%s fundamental for %s)\n",
        typ, g_type_name(G_TYPE_FUNDAMENTAL(G_VALUE_TYPE(value))), 
        G_VALUE_TYPE_NAME(value));

generates the following print:

[gperl_value_from_sv] type - 72 (GBoxed fundamental for GdkRectangle)

so it goes into the appropriate branch of the switch. BOXED

Dumper of the parameters passed to the callback in perl show what's
expected at this point, that the parameter is assumed to be
GtkRectangle.

$VAR1 = bless( do{\(my $o = 136665064)}, 'Gtk2::Button' );
$VAR2 = bless( do{\(my $o = 136910080)}, 'Gtk2::Gdk::Rectangle' );
Not an ARRAY reference at ..//Gtk2.pm line 127.

i'm looking into it, but this part of the code is new to me. (good
excuse to learn it.)
