create a Gtk::Pixmap, and set a Gtk::Gdk::Pixmap into it.  Gtk::Pixmap 
is a widget that displays an image; you can then pack the Gtk::Pixmap 
anywhere you like.

  # load the XPM from a disk file.
  # assume that $widget is part of the window into which this
  # pixmap will be placed, so that it has the same visual
  # and depth.
  ($icon, $mask) = Gtk::Gdk::Pixmap->create_from_xpm
                            ($widget->window, undef, $filename);
  # now create a Gtk::Pixmap with that xpm...
  $pixmap = Gtk::Pixmap->new ($icon, $mask);
  $pixmap->show;
  # and put it in a window.
  $widget->add ($pixmap);


this is MUCH easier in gtk2-perl --- Gtk::Pixmap's replacement in 
gtk2-perl is Gtk2::Image, and Gtk::Gdk::Pixmap is for all intents and 
purposes replaced by Gtk2::Gdk::Pixbuf, which can be loaded from a file 
with a single function call.

  $image = Gtk2::Image->new_from_file ($filename);
  $image->show;
  $widget->add ($image);

because a GtkWindow is not a GdkWindow --- it *contains* a GdkWindow.  
i think you want to do this:

$gtkwindow->window->set_decorations ('border');

personally i found Gtk::reference lacking --- it was only good if you 
already knew the C function to use and just needed to find the name of 
the perl method.  it includes no actual text explaining the functions, 
and as such has extremely limited usefulness.  that said, it was rather 
helpful to have for searching.

a file like Gtk::reference can be generated from the gtk2-perl source, 
but again, it will lack the helpful explanations that appear in the 
gtk+ API reference.  we are very reluctant to write full documentation 
because of the duplication of effort that would be involved.

however, let me reiterate a standing invitation and call for help: we 
need documentation and documenters.  this includes anyone who is 
willing to attempt to figure out how to autogenerate API reference 
documentation for the perl bindings.
