[news.eclipse.platform.swt] Re: Text field that allows only currency ent

[Charlie Surface <csurface@xxxxxxxxxx>]

The Text widget can have a VerifyListener, which will allow you to 
modify and cancel key events.  Of course, you will need to implement 
your own pattern matching.  There may also be a JFace class which does 
this, although I don't know which one.
