How to format number in (Number)TextField?

[Kamil Paśko]

Dear Wicket user group,

I have a TextField (but I can use NumberTextField as well) and when user 
types a number I want that:

1) number is positioned to the right

2) thousands are separated by spaces

3) floating point character is "."

How can I "force" that format in a TextField?

Kind regards,

Kamil
