Всички визуални компоненти се изреждат във декларацията enum в началото на файла.
В "generated_defineMask" тези визуални компоненти се представят на pvbrowser.
В "show_mask<X>" виждате цикъл, обработващ събитията. За всяко събитие се извиква slot функция. Така можете да програмирате почти всичко в тези slot функции.
