I am not sure why you are having problems with the GtkEntry callback.
I use it in the way you describe, and I am not having any problems.
I have built a layer on top of a few of the Gtk widgets so I can
capture user entry in my persistent storage transparently. Once the
widget has been attached to the data, all updates to the data by the
user, or other code are automatically propagated to any widget
attached to the data.
static void entryChanged_CB(GtkWidget* entry, RegUiEntry* ui)
{
entryCheck(ui);
}
:
gtk_signal_connect(GTK_OBJECT(entry), "changed",
GTK_SIGNAL_FUNC(entryChanged_CB), ui);
