GTK changing background image of window

how can I achieve it? I was searching for it for like 30 minutes and found examples which don't work or work in bad way. I simply want to change background image of window without changing bakgrounds of other dialogs windows etc? But I want buttons and labels to be transparent 开发者_如何学Goon that background.

I found a python example that worked for me at:

http://islascruz.org/html/index.php/blog/show/Image-as-background-in-a-Gtk-Application..html

Code

#!/usr/bin/env python
import gtk

def draw_pixbuf(widget, event):
        path = '/home/markuz/wallpapers/WMwall1024x768.gif'
        pixbuf = gtk.gdk.pixbuf_new_from_file(path)
        widget.window.draw_pixbuf(widget.style.bg_gc[gtk.STATE_NORMAL], pixbuf, 0, 0, 0,0)

window = gtk.Window()
window.set_title('Drawing Test')
window.set_size_request(640,480)
window.connect('destroy',gtk.main_quit)
hbbox = gtk.HButtonBox()
window.add(hbbox)
hbbox.connect('expose-event', draw_pixbuf)
button = gtk.Button('Press Me!')
hbbox.pack_start(button, True, False, 10)
window.show_all()

gtk.main()

I also found a C example at:

http://www.gtkforums.com/viewtopic.php?t=446

Code

GtkWidget *SetupWindow(gchar *data,gboolean Transient)
{
    GdkPixmap *background;
    GdkPixbuf *pixbuf;
    GdkScreen *ourscreen;
    GdkColormap *colormap;
    GtkStyle *style;
    GdkColor fg;
    GdkColor bg;
    GError *error = NULL;
    GdkRectangle *rect;
    GtkWidget *window;

    pixbuf = gdk_pixbuf_new_from_file ("pics/fb.png",&error);
    if (error != NULL) {
        if (error->domain == GDK_PIXBUF_ERROR) {
            g_print ("Pixbuf Related Error:\n");
        }
        if (error->domain == G_FILE_ERROR) {
            g_print ("File Error: Check file permissions and state:\n");
        }

        g_printerr ("%s\n", error[0].message);
        exit(1);
    }
    gdk_pixbuf_render_pixmap_and_mask (pixbuf, &background, NULL, 0);
    style = gtk_style_new ();
    style->bg_pixmap[0] = background;
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title (GTK_WINDOW (window), data);
    // gtk_window_maximize(GTK_WINDOW(window));
    gtk_window_set_modal (GTK_WINDOW (window),TRUE);
    gtk_window_set_default_size(GTK_WINDOW(window),640,480);
    gtk_widget_set_style (GTK_WIDGET(window), GTK_STYLE(style));
    gtk_window_set_position(GTK_WINDOW(window),GTK_WIN_POS_CENTER_ALWAYS);
    gtk_container_set_border_width(GTK_CONTAINER(window), 14);
    if(Transient==TRUE)
    gtk_window_set_transient_for(GTK_WINDOW (window),GTK_WINDOW(mainwindow));
    gtk_widget_show (window);
    return(window);
}

But I didn't try it.

It works!
