Hi,

thanks for your answer. It works now. Looks really good now. Cool!

To the second question (hope it is now understandable ;-) ):
When hildon_home_applet_lib_foreground() is called  I update my GUI
(cheking the events,  birthdays,  todos). This needs about 1-3 seconds
(the contacts search (for birthdays) needs most of the time). This long
the home-screen (eg. the other applets) hangs and you just see gray
rectangles. So I thought put the gui updating (including events, todo,
birthday readings) in another process or so. In Java/Python I would
start a new thread creating the gui. How should I solve this issue in c?

And then a third question:
At hildon_home_applet_lib_deinitialize() I should free all allocated
mem. Is it enough to free the main widget (called frame in your example)
to free all gtk related stuff, eg.

    if (osso)
        osso_deinitialize (osso);
    if (frame) gtk_widget_destroy(frame); //frame is the main widget
    frame=NULL;

(by the way I do nowhere use malloc.)
Sorry for the beginner questions.

Thanks in advance,
Chris
