Testing the “Keyboard” unit on my Mac.
CODE:
{$mode delphi}{$H+} // DOES NOT MATTER IF THIS IS INCLUDED OR NOT //
uses
keyboard;
var
K:TKeyEvent;
begin
InitKeyboard;
While GetKeyEventChar(K)<>'q' do begin
If Keypressed then begin
K:=GetKeyEvent;
K:=TranslateKeyEvent(K);
Write('* Got key event with ');
Case GetKeyEventFlags(K) of
kbASCII :Writeln('ASCII key');
kbUniCode :Writeln('Unicode key');
kbFnKey :Writeln('Function key');
kbPhys :Writeln('Physical key');
kbReleased:Writeln('Released key event');
end;
Writeln('Got key : ',KeyEventToString(K),' #',Ord(GetKeyEventChar(K)));
End;
End;
DoneKeyboard;
end.
I found so far using iTerm2:
Function Key - working
Ctrl-A must be pressed twice to return #$01
Ctrl-Z must be pressed twice to return #$1A
All other Ctrl sequences worked fine
Alt-Left returns Key with scancode 39680
Alt-Right returns Key with scancode 40192
Alt-Up returns Key with scancode 38912
Alt-Down returns Key with scancode 40960
However, Alt-Key sequences are not returning as Unicode (as I thought
they should), instead it lops twice and gives me #195 then #165 for Alt-A,
while Alt-[ returns #226, #128, #156 as “ASCII key”.
Switching to Apple’s Terminal:
Function Key - working
Ctrl-A must be pressed twice to return #$01
Ctrl-Z must be pressed twice to return #$1A
All other Ctrl sequences worked fine
Alt-A works fine.
DIFF: Alt-Up Arrow, Alt-Down Arrow does not return anything, yet…
Alt-Left returns Key with scancode 12288
Alt-Right returns Key with scancode 8448
* Obviously, I am seeing a variance based upon the terminal app. Is this
expected? I never see “released key event”, is that expected in a terminal also?
Also on both terminals, if I do Ctrl-A release, then Alt-A, I see “Got key :
SHIFT" and the ALT-A output.
