Special Characters

[donricouga]

Is there any way to prevent a user from entering special characters (i.e. ©, ®, ™, ¶, And Others) into a javax.microedition.lcdui.TextField ??? This gets submitted to a java based webservice which doesn't like these unconvertible UTF-8 characters.

I'm pretty sure there are filters you can use for the fields... you could subclass TextFilter and roll your own, though that seems to be a RIM class as opposed to the javax package.

Have you tried subclassing TextField and doing that?

I just implemented ItemStateListener on my midlet and used that to watch the characters that go into the textfield. I wanted to avoid that because i don't need the extra overhead. I was hoping there was an input constraint built in, but oh well.
