moga bermanfaat... :wink:

aku gak senang ubah sourcenya aslinya dari delphi... kalo nanti tracing ikut2 itu source... ohohoh... aku juga pernah buat scroll di dbgrid di delphi 7... hohoho.... setiap kalo tracing masuk unit dbgrid.pas nya... malas.... kalo mau buat button isa warna ganti panel aja.. hohohoho....

kalo pengin lebih animatif, artistik pake TImage aja............

trima kasih atas jawabannya.. wah tapi itu code nya banyak bener.. untuk pemula sungguh bener2 pusing..

bukannya banyak bener, masukkan sebagai salah satu komponen di IDE jadi tinggal diletakkan pada form atau kalau yang komponen yang lain bisa cari di torry, banyak loh ...
