Thanks!
So i could replate enter and leave to g_iddle_add, right?
gdk_threads_enter();
g_printf("UpdateConfigNow\n");
iUpdateConfigNow();
gdk_threads_leave();
To
g_idle_add((GCallback)iUpdateConfigNow, NULL);
Why i get this error?
Main.c:1824: undefined reference to `g_iddle_add'
Thanks

In gdk manual i see thath gdk_threads_enter and leave has been
deprecated and alll gdk and gtk+ calls should be made from main thread.
How we do this? Someone have any example?
You have to call g_idle_add (that is thread safe) every time you need to update
one or more widgets from an external thread.
Let's think about a common situation, for instance you are encoding a video
file and you want to update a progress bar:
[from encoding thread]
struct progress {
char label[50];
float value;
};
myprg = malloc(sizeof(struct progress));
myprg->value = 75.0;
strncpy(myprg->label, "Second pass", sizeof(myprg->label));
g_idle_add((GCallback)progress_update, myprg);
gboolean progress_update(struct progress *p);
{
gtk_progress_bar_set_text(p->label);
gtk_progress_bar_set_fraction(p->value);
free(p);
return FALSE; // it means that you want to run this only once
}
