Re: Many questions

I'm using these function in a GUI application (see protocoltool on sourceforge); when the connection is made/closed, the GUI's controls are enabled/disabled. 2) Can an application load a linux kernel module? For example, my application may need i2c drivers. Does glib/gtk/gnome have anything to load kernel modules? How can it be done? yes they can. The program modprobe does this. I just did a strace of modprobe when it load a module and discovered init_module manpage: http://linux.die.net/man/2/init_module Perhaps you read the source code of modprobe for more details. 3) Now, for unrelated questions, what are the hook functions used for? They look interesting, but being an amateur programmer, I have no idea of the context where they may be used. Are they useful in an user application? They are a sort of callback functions. A nice example are gtk_about_dialog_set_email_hook gtk_about_dialog_set_url_hook The hook functions get called called when the user press the email or url link in the about dialog. Then in the hook function you can open another program e.g. browser or emailclient. hth Alex 4) How do we properly use the g_cancellable functions and when are these used?

}
(don't laugh about the stream thing. If someone could give me a hint to
make that better would be great.)
and this is the callback:
void on_menugroup_items_activate (GtkObject *object, gpointer user_data)
{
cout Gruppe (int) user_data endl;
}
So the callback just print the number of the chosen group.
And this work.
But
1. During compilation i get a warning about
'cast to pointer from integer of different size'
for the g_signal_connect line. How can i avoid this?
2. It is normal that the callback is called twice?
For example if group 3 is marked and i change to 5 i get
Gruppe 3
Gruppe 5
then marking group 9
Gruppe 5
Gruppe 9
Is that normal?
3. When i choose group 1 the callback always produces
Gruppe 1
Gruppe 0
regardless from the previous group.
Why?
any ideas would be much appreciated..
