Kalo dengan proses message bagaimana? soalnya akan digunakan untuk pemanggilan procedure yang lain.

Gak perlu rumit2 pake message segala. Hampir seluruh kontrol punya property Focused (boolean). Tinggal iterasi aja seluruh control dalam form dan baca property tsb, akan ketahuan yg mana yg sedang fokus. HTH. ;)

wakakak... ngga' perlu iterasi segala :mrgreen:
1. akses aja property ActiveControl milik TForm, atau
2. gunakan WinAPI GetFocus: HWND - GetFocus retrieves the handle of the window that has the keyboard focus, if the window is associated with the calling thread's message queue, atau
3. gunakan WinAPI GetActiveWindow: HWND - GetActiveWindow retrieves the window handle to the active window associated with the thread that calls the function
silahkan pilih salah satu... atau kombinasi ketiganya :mrgreen:
jika menggunakan WinAPI, utk mendapatkan nama komponen tersebut cukup gunakan fungsi berikut:
var AW: HWND;
begin
AW:= GetActiveWindow; // GetFocus
if AW <> 0 then AName:= FindControl(AW).Name;
end;
