GTK_COMBO_BOX callback

["Leon Ross" <subaruwrx88011 gmail com>]

I have recently change all my combo boxes from GTK_COMBO to GTK_COMBO_BOX.
Now my call backs are all wrong. What should I use?

This is what I was using before the change.
g_signal_connect_swapped(GTK_OBJECT(GTK_COMBO_BOX(ms_processComboBox),"changed",
  G_CALLBACK(process_selected), (gpointer)ms_messageComboBox);

Thanks
