I did it once and it went somethig like it:

Study every character that is inserted on the textfiel. There must be a JAVA routine for that.

For STRINGS, let it run free...

For INTEGERS, let only numbers be entered. If an "A" is entered, make Length(TEXT)=Length(TEXT)-1, e.g: Turn "123A" into "123" and write it on textfield.

For real numbers, let only 1 'point' be entered.
