Topic: Призраки My Visual Database

Ранее я писал о классе TTabControl , который имеется в MVDB, но практически бесполезен.

Недавно обнаружил ещё одного признака - TTrackBar.


Его можно призвать к жизни несложным заклинанием, но вот использовать его не получится - отсутствует возможность добавить обработчик  onChange на сдвиг ползунка.

Re: Призраки My Visual Database

Получается автор и не собирался этот компонент использовать, но видимо он с чем-то подтянулся? или случайно обрубил обработчика ?
