{
I would like to detect more than 2 keys being pressed within a form.
For example I would like to know if the user pressed
time. The onkeydown seems to only check for one or two keys max but surely
you can determine what keys are currently down.
}
// You can use GetKeyState:
procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
Shift: TShiftState); begin
If ((GetKeyState(VK_CONTROL) AND 128)=128) and ((GetKeyState(VK_F5) AND 128)=128) and ((GetKeyState(ord('8')) AND 128)=128) then ShowMessage('CTRL+F5+8 Pressed'); end;
( Remember: Form1.Keypreview := TRUE )
// Or you can read the entire KeyBoard Status,
// and later check for the three keys:
procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
Shift: TShiftState); var KeybState: TKeyboardState; begin GetKeyboardState(Teclado); If ( (KeybState[VK_CONTROL] and 128)=128 ) and ( (KeybState[VK_F5] and 128)=128 ) and ( (KeybState[Ord('8')] and 128)=128 ) then ShowMessage('CTRL+F5+8 Pressed'); end;
