Hi Everyone. This may be a bug, I do not know. Observe the following
snippet in the script of the stack:
on keyDown theKey
local theModifier
put "" into theModifier
switch
case the optionKey is down
put "Opt " after theModifier
case the CommandKey is down
put "Cmd " after theModifier
case the shiftKey is down
put "Shft " after theModifier
case the controlKey is down
put "Ctrl " after theModifier
end switch
put char 1 to -1 of theModifier into theModifier
replace " " with "-" in theModifier
put theModifier && theKey
pass keyDown
end keyDown
This SHOULD put the modifier keys and the key typed in the result of
the message box. It works when I just type letters. BUT when I use a
modifier that is NOT the shift key, I get NOTHING. IF I use the Shift
key I get "Shft-Crtl " followed by the letter typed, even though the
Control key is NOT down!
Well this cannot be right! What is really needed is a new argument in
the keyDown and keyUp handlers for the modifier keys. I should be able
to write the handler this way:
on keyDown theKey, theModifiers
if "Shift" is in theModifiers then
-- some stuff here
end if
pass keyDown
end keyDown
I guess this is a bug report AND a feature request.
It's not a bug, it is how keydown works. The keydown message only
reports, for the most part, typeable keys. In the case of the option
key, for example, no keypress is generated until you also press another
key; that is how, on a Mac, you make international characters.
You can use rawKeyDown instead to catch a few of the other keys, such as
delete, tab, and the arrow keys. See the docs. The rawKeyDown message
receives the keypress as a number rather than as a character, so you
need to interpret those. We can help you if you need it.
But some keys are simply never reported by the operating systems during
normal keyboard input. Modifier keys like shift, command, control, and
option are not reported, so Rev can't know about them. If you need to
know the state of some of these keys, you can use the keysdown()
function, which specifically checks to see if they are depressed.
It is common for new users to think unexpected behaviors are bugs, so
I'm glad you asked here first. It's always a good idea.
