hi all,
                      I'am a newbie here. i'am developing a user agent
client , for a Telephony application using GTK+-1.2. The whole
application has 5 threads running , i try to update a label , with
gtk_label_set_text () , when some event occurs in the application , but
it doesnt seem to take affect . When i use it with a debugger and when i
single step code , everything appears to be fine . Could someone help me
to overcome this problem.
    

Read the threads section of the api-manual of gtk and gdk, and the usage
of gdk_threads_enter() and gdk_threads_leave(). Sounds very like thread
race problem. For all glib events, you need to call
gdk_threads_enter()/gdk_threads_leave by hand. Events that comes from gtk,
already holds this lock.

gtk main looks like this

while (!quit)
{
 gdk_threads_leave(); /* unlock */
 let_glib_run_until_we_have_a_event;
 gdk_threads_enter(); /* lock*/
 handle_events;
}
