Yeah, I feel your pain with trying to get to the lowlevel stuff in the docs. For what it's worth, I asked a similar question awhile back on the gtk-perl maillist, on whether you could set a style from a base64 encoded xpm contained within the file. The answer was "no". You would need to write it to a temp file, then incorporate it in as a style.

If you think about it, a background pixmap probably needs to be setup before anything can be drawn onto it. The normal method they are setting up, is to use styles, and have your pixmaps stored under a style name in the styles directory. So maybe it will take them a few years to get around to it. :-)

Another problem I've experienced with a Gdk window, is that it is not there until the window is mapped onto the screen. In the code below, if you try to get the gdkwindow in the main program, before show_all() is called, it will be undefined. The following is the closet I could get to what you want to do. It runs without error, but the background does not change, neither for a pixmap, nor a color. There probably is some command needed to redraw the window? I don't know, but if you find a way, please post it.

#!/usr/bin/perl
use warnings;
use strict;
use Glib qw/TRUE FALSE/;
use Gtk2 '-init';

 my $rc_style = Gtk2::RcStyle->new;
 $rc_style->bg_pixmap_name('normal', 'bunny.xpm');

my $window = Gtk2::Window->new('toplevel');
$window->set_title('Embed test');
$window ->signal_connect( 'destroy' => \&delete_event );
$window->set_border_width(10);
$window->set_size_request(500,500);

$window->modify_style ($rc_style);


my $vbox = Gtk2::VBox->new( FALSE, 6 );
$window->add($vbox);
$vbox->set_border_width(2);

my $hbox= Gtk2::HBox->new( FALSE, 6 );
$vbox->pack_end($hbox,FALSE,FALSE,0);
$hbox->set_border_width(2);

$vbox->pack_end (Gtk2::HSeparator->new, FALSE, FALSE, 0);

my $button = Gtk2::Button->new_from_stock('gtk-quit');
$hbox->pack_end( $button, FALSE, FALSE, 0 );
$button->signal_connect( clicked => \&delete_event );

my $button1 = Gtk2::Button->new('Set BG');
$hbox->pack_end( $button1, FALSE, FALSE, 0 );
$button1->signal_connect( clicked => \&set_bg );

my $vbox1 = Gtk2::VBox->new( 0, 5 );
$vbox->pack_end ($vbox1, TRUE, TRUE, 0);


my $btn = Gtk2::Button->new_from_stock('gtk-quit');
$btn->signal_connect( 'clicked' => \&delete_event );

$window->show_all();

If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
