Callback Question

[Matí­as Alejandro Torres <torresmat gmail com>]

Hi,

Can I call GTK Functions that modifies the GUI inside a callback?

Just an example:


/*CALLBACK*/
void text_to_upper_callback (GtkEntry *entry, gpointer data) {
   /* I modify the GUI by setting the text of an entry */
   gtk_entry_set_text (entry,
                                    g_utf8_strup (gtk_entry_get_text 
(entry), -1)));
}


void* init () {
   [...]
   g_signal_connect (entry, "activate", (GCallback) 
text_to_upper_callback, NULL);
   [...]
}
