Restrict certain keyboard keys

[davidmills]

On my Android why does only the on returnInField work and yet none of the others do?
Thanks
Dave

Code: Select all

on openField
mobileSetKeyboardType "numeric"
end openField

on returnInField
   beep
   exit to top
end returnInField

on commaInField
   beep
   exit to top
end commaInField

on spaceInField
   beep
   exit to top
end spaceInField

end keyDown

Hi Dave,

You can use keyup to do that

Code: Select all

on keyup pKey
   if pKey is in "abc" then
      beep
   else
      put pKey
   end if
end keyup

Have also a look to keydown, rawkeydown, rawkeyUp
Best regards

Just to elaborate, the engine sends different messages when things happen. One of the engine messages is enterInField which is sent when the enter key is pressed in the field. There is no such message for comma, or most alphanumeric keys. So you need to use the more generalised messages as Jean-Marc says.

Hi Dave,

the answer is quite simple: If it is not listed in the DICTIONARY (hint, hint!), then it is not build-in!

Thanks for all your replies. But I don't understand from the example what I'm supposed to replace my present script with, other than I presume the "abc" is the field name.
Thanks

Hi Dave

"abc" is the field name.

No that is a list of chars you want avoïd.

[davidmills]

Thanks and whilst is now working OK. Is there a way to remove the incorrect characters whilst still in the field other than doing a manual delete?

What about this:

Considering you don't want a, b and c characters:

Code: Select all

put replaceText( theText, "[abc]", empty)

Thank you Thierry. It's the comma and space I don't want, but where do I add your script line as I tried line 13 after beep?

on openField

on returnInField
   beep
   exit to top
end returnInField

on keyup pKey
   if pKey is in ", " then
   beep
   else
   put pKey
end if
end keyup
