Simulate keypress in a script

[richmond62]

if one does this in a cardScript:

Code: Select all

on rawKeyUp PP
put PP
end rawKeyUp

one ends up with 65363 in the messageBox

this is the code the operating system uses for the right arrow key

However, it is also a Unicode glyph address (0xFF53): http://www.unicode.org/charts/PDF/UFF00.pdf

and this is why an 's' gets dumped in a field when one does this sort of thing:

Code: Select all

type numToCodePoint(65363)

this

Code: Select all

type "arrowKey right"

inserts "arrowKey right" at an insertion point

and

Code: Select all

send "arrowKey right"

does nothing

I think Richard or Klaus should move this thread to "Talking Livecode". It is not a feature request, per se, though I bet the OP wishes it were.

At the very start of the Unicode "thang" there are lots of what are called 'control characters'
(which I cannot understand). I suppose one of the ways to send and/or type
what an arrowKey right does is to find out which control character
in the Unicode set does this . . .

my pseudoCode would do this:

put the altKey into right

and then something like this:

https://www.alt-codes.net/arrow_alt_codes.php

What I mean, is somehow set the stack to see the altKey as Down.

[richmond62]

What, perhaps, should be pointed out, is that as LiveCode is (at least partly) cooked in C++
there are ways to fake arrow keys in C++

VK_UP, VK_DOWN, VK_LEFT, VK_RIGHT

which, presumably, could be rolled into LiveCode without undue fuss.

One of the snags here is that, while in javaScript and so on one can play around with
the keycode of a key on a keyboard, and find out that the keycode for the left arrowKey is 37, and the right arrowKey is 39, and then make use of that information, I for one cannot work out how one might do that in LiveCode.

LiveCode, frustratingly, mentions this:

but then lets one down with a damp squib.
