gtk_button_new_with_label does it in that way. I do not think that it
will be wrong.

This works:

  button = gtk_button_new ();
  bitmap = gdk_bitmap_create_from_data (NULL,
                                        eject_bits,
                                        eject_width, eject_height);
/*  pixmap = gtk_pixmap_new (bitmap, bitmap, bitmap, bitmap, bitmap);*/
  pixmap = gtk_label_new("Tach");
  gtk_widget_show(pixmap);
  gtk_container_add (GTK_CONTAINER (button), pixmap);
  gtk_box_pack_start (GTK_BOX (box2), button, TRUE, TRUE, 5);
  gtk_widget_show (button);

But this produces a core:

  button = gtk_button_new ();
  bitmap = gdk_bitmap_create_from_data (NULL,
                                        eject_bits,
                                        eject_width, eject_height);
  pixmap = gtk_pixmap_new (bitmap, bitmap, bitmap, bitmap, bitmap);
/*  pixmap = gtk_label_new("Tach");*/
  gtk_widget_show(pixmap);
  gtk_container_add (GTK_CONTAINER (button), pixmap);
  gtk_box_pack_start (GTK_BOX (box2), button, TRUE, TRUE, 5);
  gtk_widget_show (button);

Quite strange. But in the end I found that this does work:

  button = gtk_button_new ();
  style = gtk_widget_get_style(button);
  pixmap1 = gdk_pixmap_create_from_xpm(window->window,
                                       &style->bg[GTK_STATE_NORMAL],
                                       "xpm/eject.xpm");
  pixmap = gtk_pixmap_new (pixmap1, pixmap1, pixmap1, pixmap1, pixmap1);
  gtk_container_add (GTK_CONTAINER (button), pixmap);
  gtk_widget_show(pixmap);
  gtk_box_pack_start (GTK_BOX (box2), button, TRUE, TRUE, 5);
  gtk_widget_show (button);
