Text field that allows only currency entry [message #454972]

I'm a new SWT / Eclipse user and I'm looking for a simple way of
creating a text entry field into which a user may enter only a dollar
amount ($46.78 for instance). I am not concerned at this point in
internationalization as this is an in-house project and will not need to
be used in non-dollar countries. My ideal widget would only allow a user
to enter numeric digits and $,.
but having the widget perform some type of validation after an entire
entry has been made would also work.

Any hints /help would be appreciated.

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.

See:

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet179.java?rev=HEAD& amp;content-type=text/vnd.viewcvs-markup

This snippet formats a date but the concept could be used to format
currency.
