Simulate key press

[jacque]

Do you think this is worth mentioning? I have always been comforted by believing that an xTalk IDE was so flexible and accessible that, generically, " being able to invoke an arrowKey message under script control" was, simply, doable.

Did I mention that other instances of that pipe dream required kluges?

LC doesn't allow scripts to override its own messages, unlike HC, but that's a different thing. Are there other keywords that can't be "sent"? If so, then it's apparently intentional for some reason. If not, then it might be worth a mention.

As far as I can see the reason why it doesn't seem possible to invoke an arrowKey signal via script is
because, unlike a mouseDown the thing consists of 2 components:

It might (?) be an idea to submit an enhancement request of this sort:

send "arrowKey"("up")

[richmond62]

Come to think of things, a series of this sort would be useful:

send "keyUp"("r")


send "rawKeyUp"(114)

Try the "type" command?

I tried type.

and wondered how I would get the buttonScript to type "Аз харесам кашкавал"
by sending rawKey codes and having a Bulgarian keyboard layout selected on my computer.

This kind of banal and obvious script:

and

type3.png (12.69 KiB) Viewed 4487 times

(Having checked that script: it does NOT work)

>>> work (and kudos to the Livecode people for everything working in a straightforward way
with a non-Latin writing system). <<<

How do I type the arrowKey "down"?

[richmond62]

To explain in a little more detail:

Here's a cardScript:

on arrowKey AX
switch AX
case "up"
--do procedure #1
break
case "down"
--do procedure #2
break
end switch
end arrowKey

Now; how could I have a button which contains this sort of (pseudocode):

on mouseUp
send "arrowkey"("up") to card id 2001
end mouseUp

and, similarly with rawKey values?

[jacque]

I wouldn't think you need to send an arrowkey message at all. Just separate the actions from the handlers:

Code: Select all

on arrowKey AX
  switch AX
    case "up"
     procedure!
      break
    case "down"
     procedure2
      break
  end switch
end arrowKey

on mouseUp
  procedure1
end mouseUp

on procedure1
  -- stuff
end proceudre1

on procedure2
  --stuff
end proceudre2

Or you could combine them:

Code: Select all

on procedure pNum
  switch pNum
    case 1
      -- procedure 1 stuff
      break
    case 2
      -- procedure 2 stuff
      break
  end switch
end proedure
