On 12/10/98 D. Emilio Grimaldo Tunon uttered the following other thing:

GtkWidget *button;
GtkWidget *pixmap;
GdkPixmap *pix1;
GdkBitmap *mask1;
GdkPixmap *pix2;
GdkBitmap *mask2;
/* Create the button without a label */
button = gtk_button_new ();
/* Generate your pixmap */
pix1 = gdk_pixmap_create_from_xpm (window, &mask1, style->bg[GTK_STATE_NORMAL],
xpm_filename);
pix2 = gdk_pixmap_create_from_xpm (window, &mask2, style->bg[GTK_STATE_NORMAL],
xpm_filename);
/* Create a gtk pixmap */
pixmap = gtk_pixmap_new (pix1, mask1);
/* Add the pixmap to the button */
gtk_container_add (GTK_CONTAINER (button), pixmap);
gtk_widget_show (pixmap);
gtk_widget_show (button);
/* When you want to switch, change the pixmap
* Typically, you would probably set up a periodic timer to do this for
* an animation
*/
gtk_pixmap_set (GTK_PIXMAP (pixmap), pix2, mask2);
There you go. Or, you could embed a drawing_area in the button instead
of the pixmap, and then use standard gdk commands to animate or draw on
the "button".
