gtk_widget_modify_bg on a GtkTextView

[Ari Pollak <ajp aripollak com>]

Hi, I'm currently using Gtk2-perl for a small application (I'm so glad
I found this module, I put this off for a while becuase I thought there
was no Gtk2 module, and doing this in C would have been incredibly
time-consuming).

My problem is that when trying to set the default background color of a
GtkTextView, no change seems to take place. According to the API docs,
you should be able to set the properties of an entire TextView with the
gtk_widget functions. Gtk2::Widget->modify_font() works fine, but
Gtk2::Widget->modify_bg() has no effect. Is this supposed to happen with
a TextView? Any ideas? Following is some example code:

my $window = Gtk2::Window->new ('toplevel');
my $view = Gtk2::TextView->new;
my $color = Gtk2::Gdk::Color->parse('green');
$view->modify_bg('normal', $color);
$window->add($view);
$window->show_all;
Gtk2->main;

What should happen is that the background color changes to green, but
this never happens.
