Slider, chowany

Witam,

Szukam pewnego elementu w Javie, który byłby podobny do tego przedstawionego na zrzutach ekranu:

Przed rozwinięciem:

Po rozwinięciu:

Ogólnie chodzi o to, żeby slider nie był widoczny w domyślnej sytuacji. Równie dobrze strzałki do pokazywania slidera może być nie widać, tak żeby pokazywał się on dopiero po kliknięciu kursorem w pole input.

Dzięki z góry, pzdr.

Można spróbować samemu zrobić:

Wow, dzięki za odpowiedź :)

Liczyłem na coś gotowego ze Swinga w sumie. Ten chyba zawiera mały bug, tzn. po zaczęciu używania suwaka cały slider nagle znika. Mimo wszystko dzięki wielkie!

Hehe to nie bug. Jeżeli wyjdziesz myszką poza suwak (na dłużej niż 5 sek), to znika.
