Re: pixbufs in a SimpleList

I need short instructions (maybe a small sample code) to implement a

See also the stock browser portion of gtk-demo, which comes in the Gtk2 source tarball; it's a non-trivial example of using the TreeView in a real-world setting.

Here's something trivial with SimpleList.

  #!/usr/bin/perl -w

  use strict;
  use Gtk2 -init;
  use Gtk2::SimpleList; # Gtk2::Ex::Simple::List

  my $window = Gtk2::Window->new;
  $window->signal_connect (destroy => sub { Gtk2->main_quit });

  my $slist = Gtk2::SimpleList->new ('Icon' => 'pixbuf',
                                     'Stock-Id' => 'text');
  # I'm too lazy to create a bunch of pixbufs here, so i want to use
  # stock items.  Gtk2::CellRendererPixbuf can, indeed, use a stock id,
  # but the 'pixbuf' column type for SimpleList wants an actual pixbuf
  # object.  So, here's a little perl magic to render these stock icons
  # as we will the store.  Remember, the SimpleList represents the
  # TreeStore as a list of lists, so the map block must return a
  # reference an array of column values...
  @{ $slist->{data} } = map {
      #  column 0, the pixbuf              column 1, the text
      [ $window->render_icon ($_, 'menu'), $_ ]
} qw(gtk-ok gtk-cancel gtk-yes gtk-no gtk-save gtk-open gtk-quit gtk-close);

  $window->add ($slist);

I don't like... this game... when there's cannons... being shot... at me.
