Hi, I have a little problem with TextField.
I would use a TextField that allow to insert only numbers and comma symbol (or dot symbol).
Ther's some class that allow these operations?

hey, if you have the J2ME wireless tollkit installed, the MIDP API can be found under <j2mewtk root>\docs\api\index.html look up the index for t, textfield has a number of constraints that can be applied to texfields. the only ones that are suitable for you are probably email or numeric constraints. is it possible you could add in the comma or dot later?

Thank you for reply. I need that people inserts Euro value into a TextField. (i.e. 34,50)
If I use a Numeric Costrain, the comma is impossible to be insert. So, how I can identify the right position of the comma (or dot)?
Otherwise, if I use an Email Constrain the User can insert every kind of character. This is not a problem for me, but I would like to give a user-friendly Interface.
So if I need to insert the number value 3, I need to be able to push just one time the button 3, and not more times.
Have you or some one, an answare to this problem?
