How to write an applet?

[Andreas Sliwka <goff nef wh uni-dortmund de>]

Hi,
  after searching developer.gnome.org for more than one hour I now give up
and ask you: Where do I find a information how to write a gnome panel applet
that compiles with the last stable gnome? I found the tutorial from Gerg~o
'Erdi, but it does not work with my libs. It compiles, but starting it I get:

---------
Gtk-WARNING **: gtk_type_create(): unknown parent type `21'.

GLib-CRITICAL **: file ghash.c: line 138 (g_hash_table_lookup): assertion `hash_table != NULL' failed.

GLib-CRITICAL **: file ghash.c: line 152 (g_hash_table_insert): assertion `hash_table != NULL' failed.

GLib-CRITICAL **: file ghash.c: line 138 (g_hash_table_lookup): assertion `hash_table != NULL' failed.

GLib-CRITICAL **: file ghash.c: line 152 (g_hash_table_insert): assertion `hash_table != NULL' failed.
---------- 
  .. and thatīs just the beginning of it ...
