Re: Help, How to mange the id returned by g_timeout_add

[Micah Carrick <email micahcarrick com>]

Well, I'm hardly the expert, but I typically declare things like that in 
main() and pass them to the routines and callbacks as userdata if it's 
needed. For example, let's say you have an array of guint's to hold each 
of your timer id's (or if you don't know how many you'll have, perhaps a 
GSlist of guint).

#define TIMER_ID_COUNT 4

/* array containing 5 timer id's */
guint timeout_id_array[TIMER_ID_COUNT];

/*
... calls to g_timeout_add() storing
the return values in the timeout_id_array array...
*/

g_signal_connect(G_OBJECT(button1), "clicked",
           G_CALLBACK(on_button1_clicked), timeout_id_array);

/* or if you're using libglade */

glade_xml_signal_connect (gxml, "on_button1_clicked",
               G_CALLBACK(on_button1_clicked), timeout_id_array);

I've even put some data into structures when I'm passing the same group 
of data
around a lot. That way I only have to pass one pointer. But then again, 
I haven't
been doing this very long. I'm sure there are better ways.
