En el "enum" arriba del todo del fichero, se puede ver la lista de todos los widgets definidos.
En "generated_defineMask" esos widgets se hacen conocidos para el cliente pvbrowser.
En "show_mask<X>" se encuentra el loop de eventos. Para cada evento se llama a una función de slot. Así puedes programar prácticamente todo lo que quieras dentro de estas funciones de slot.
