Viktoras, here's a handler that will stop the backspace and delete keys
working in a text field. I hope I understand you correctly, because I
was struggling to think of a use for this! Like Jim says, you may want
to handle the cutKey message, etc. This handler blocks multi line
selecting and then a keypress if the selection contains a return character.
on rawKeyDown pCode
if pCode is not among the items of "65288,65535" then pass rawKeyDown
put word 2 of the selectedChunk into tStart
put word 4 of the selectedChunk into tEnd
if tStart <= tEnd then
put char tStart to tEnd of me into tSelection
if return is not among the chars of tSelection then
pass rawKeyDown
end if
else
if pCode = 65535 then
put tStart into tPos
else
put tEnd into tPos
end if
if char tPos of me <> return then
pass rawKeyDown
end if
end if
end rawKeyDown

can anybody suggest a simple method to prevent users deleting linefeeds in a
text field when pressing backspace or delete keys. It should allow deletion
of any other symbol which is not "return" and should not use table object at
all.
What should be added into the handler below?
Chunk expression (word 2 of the selectedchunk) > 1 does not work...
on backspaceKey
if ??? then
pass backspaceKey
end if
end backspaceKey
