Subject: [GTK] Toolbar, Gdk::Pixmap::create_from_xpm_d


Hi,

This is my code:

#v+
#!/usr/bin/env ruby

require 'gtk'

$reload_xpm = [
  "16 14 3 1",
  ". c None",
  "a c #000000",
  "# c #7b7b7b",
  ".....##aaa#.....",
  "....#aaaaaaa....",
  "...#aa#....#a...",
  "...aa#..........",
  "..aaa.......a...",
  "aaaaaaa....aaa..",
  ".aaaaa....aaaaa.",
  "..aaa....aaaaaaa",
  "...a.......aaa..",
  "..........#aa...",
  "...a#....#aa#...",
  "....aaaaaaa#....",
  ".....#aaa##.....",
  "................"
]

window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
vbox = Gtk::VBox.new(false, 0)
toolbar = Gtk::Toolbar.new
toolbar.set_style Gtk::TOOLBAR_ICONS
pixmap, mask = Gdk::Pixmap::create_from_xpm_d(window.window, nil, $reload_xpm)
pixmapwid = Gtk::Pixmap.new(pixmap, mask)
toolbar.append_item("Reload", "Reload", "Reload", pixmapwid, nil) {
  puts "hello"
}
window.add vbox
vbox.pack_start toolbar, false, false, 0
toolbar.show
vbox.show
window.show
Gtk.main
#v-

When I run it, the following message is displayed:

Gdk-WARNING **: Creating pixmap from xpm with NULL window and colormap

Moreover, when I change the lines 

    toolbar.show
    vbox.show
    window.show

to 

    window.show_all

toolbar.set_style has no effect an more; both text and icons are
displayed, even if Gtk::TOOLBAR_ICONS is used.

What's wrong?

I use:
GTK 1.2.8
Ruby-GTK 0.24
Ruby 1.6.4
