Here's how I make it work (not sure if this is the "right" way):
int register_stock_icon(GtkIconFactory *icon_factory, const char
*name, const char *filename)
{
GdkPixbuf *pixbuf;
gchar *pathname;
GError *error = NULL;
pathname = g_strdup_printf("%s%s%s", PACKAGE_PIXMAPS_DIR,
G_DIR_SEPARATOR_S, filename);
pixbuf = gdk_pixbuf_new_from_file(pathname, &error);
g_free(pathname);
if (pixbuf == NULL) return -1;
gtk_icon_theme_add_builtin_icon(name, -1, pixbuf);
g_object_unref(pixbuf);
return 0;
}
void add_icons()
{
GtkIconFactory *icon_factory;
icon_factory = gtk_icon_factory_new();
register_stock_icon(icon_factory, "gtkdisplay-main-icon",
"display_icon24.png");
register_stock_icon(icon_factory, "gtkdisplay-main-icon-large",
"display_icon48.png");
gtk_icon_factory_add_default(icon_factory);
}
My makefile is set up so that PACKAGE_PIXMAPS_DIR points to
/usr/local/share/pixmaps/<appname>
I call add_icons before I create my window.
Finally, in glade-2, I set the named icon to "gtkdisplay-main-icon",
which is equivalent to calling gtk_window_set_icon_name.
The advantage of this, over using gtk_window_set_icon_from_file is
that you can add multiple images at different sizes into the icon
factory under the same name, and GTK will pick the appropriate one to
display.
