Hi
Let have two functions:
gint aaa(void) {
gint func_id ;
.....
func_id = gtk_timeout_add(500,(GtkFunction)bbb,0) ;
...
}
gboolean bbb(gpointer data) {
g_print(" Hello world \n") ;
return FALSE ;
}
so at the first look at the function aaa it seems that it makes
a thread which is running of function bbb every half second.
But for the second look we see that it is not true - it is just calling
a function bbb with the data=NULL.
This way of calling functions has advantages: the function aaa "says" to
gtk "please call function bbb in half second". So during this half
second GTK has time to repaint, resize, ..... - good for timereal
performance. But now the question is:
Is it possible that the function aaa() "says" to system GTK:
"please execute function bbb() in max half second. If you (GTK) have
nothing to do please execute bbb() now"
OK now you can answer that then I should use gtk_idle_add instead of
gtk_timeout_add.
I do not want to do that - because in case of gtk_idle_add the bbb()
function sometimes can be never executed.
OK Some of you can say I should use gtk_idle_add with priorities:
but it somehow solved problem, but here I do not have this time
limitations: I dont know which priority to use in gtk_idle_add_priority
(or whatever name) to get max 500ms for calling the bbb() functions.
OK does anybody knows how to solve it or maybe some suggestions.
Also - still - if somebody knows a good applications which uses threads
to update status of GTK windows - please tell me which one and maybe the
link to source ;-)
Best regards
