Need Help??

take a look at the perl-gtk2 class docs. Label is a subclass of widget, which provides the get_colormap function. In your above code change:

my $colormap = $l->window->get_colormap();
[download]

to:

my $colormap = $l->get_colormap();
[download]

I have not used this but it looks right from the docs.

That does get me a little further, but now it still fails on the last line:

      my $l = new Gtk::Label( "Success" );
      my $colormap = $l->get_colormap();
      my $gdk_color = Gtk::Gdk::Color->parse_color( "green" );
      $gdk_color = $colormap->color_alloc( $gdk_color );
      $l->window->set_background( $gdk_color );
[download]

$l->window is undefined, so can't do a set_background on it, and $l->set_background doesn't appear to exist either.
