Delphi - Using the TApplicationEvents OnShortCut event to detect Alt+C key presses

Question

I am using TApplicationEvents OnShortCut event to get application keyboard short cuts in a Delphi program.

Using the following code:

procedure TForm1.App         


        

Answer 1

Like so:

procedure TForm1.ApplicationEvents1ShortCut(var Msg: TWMKey;
  var Handled: Boolean);
begin
  if (Msg.CharCode = Ord('C'))
    and (HiWord(Msg.KeyData) and KF_ALTDOWN <> 0)
  then begin
    ShowMessage('Alt+C pressed!') ;
    Handled := TRUE;
  end;
end;

Please note that using Alt and some key only is a bad choice for a shortcut, as the system uses these to activate menu items or dialog controls.
