|
Provides special processing when the user presses down on a key.
procedure KeyDown(var Key: Word; Shift: TShiftState); override;
virtual __fastcall KeyDown(Word Key, TShiftState Shift);
Applications cannot call KeyDown. It is called automatically when the user presses a key, before the KeyPress method is called.
