If "textchanged" triggers on paste, you can probably use that..
textchanged does trigger - but *after* the text has appeared. With
returninfield and pastekey I get the message first - and can prevent the
character being inserted.
In order to use textchanged, I'll need to keep a local copy of the field
content so that if I do find a CR I can restore the previous content and
selection point - but on a very quick try that does seem to work OK.
I'll have to check it out more thoroughly, and then try it on mobile,
but it sounds like it should work - thanks.

Thanks for the prompt Mike.
Short answer - don't know yet, though I suspect I'm going to have to find
out.
I do not currently have "mobile text field objects" - all I have are just
standard LC fields, so returninfield is all I need for the 'return' part of
the problem - no need for 'inputReturnKey'.
However, I also want to trap any attempt to paste in text containing CRs;
I can do that for traditional platforms with a 'pasteKey' handler - but
that doesn't seem to apply to LC fields on mobile, and also there doesn't
appear to be any direct equivalent for mobile text fields (though there may
be other ways to achieve the same result on mobile text fields - I really
haven't looked at them yet).
In fact, maybe that's the question I *should* ask.
"Should i be (can I reasonably get away with) using LC fields in an
app targeted for mobiles, or do I really need to use mobile text fields ?
Thanks
Alex.

I'm sure there must be an easy way I'm missing ..... he said in hope :-)
I want a field to contain a single line of data - i.. no CRs.
I've done the easy bit (a handler for returninfield).
I can even do the moderate bit - a 'pastekey' handler, and check for
CRs
in the clipboard - but that doesn't apply to mobile (or at least, the
dict
says it doesn't).
Is there any way to handle it on mobile ?
Thanks
Alex.
