Benoit Xhenseval updated RCP-553:
---------------------------------

    Attachment: BigDecimalTextField.java.patch

I do not know why the patch appears to be so different from the code, this is not the case. I think it is due to SVN thinking that many items have been inserted?

2 set of changes:

in insertString:
            } else if (str.length() == 1 && SHORTCUTS.containsKey(str.toLowerCase())) { //+ BX Shortcut start
                Integer shortcut = (Integer) SHORTCUTS.get(str.toLowerCase());
                if (offset == 0) {
                    str = "1";
                } else {
                    str = "";
                }
                for (int count = 0; count < shortcut.intValue(); count++) {
                    str += "0";
                }
                //+ BX Shortcut end

and a set of new methods at the beginning:
    private static final Map SHORTCUTS = new HashMap();
    private static boolean shortcutInitialised = false;

    private static void initialiseShortcut() {
	    if (!shortcutInitialised) {
	        final Object o = ApplicationServicesLocator.services().getService(MessageSourceAccessor.class);
	        if (o instanceof MessageSourceAccessor) {
	            MessageSourceAccessor messageSourceAccessor = (MessageSourceAccessor) o;
	            addShortcut(messageSourceAccessor, "BigDecimalTextField.shortcut.hundred", new Integer(2));
                addShortcut(messageSourceAccessor, "BigDecimalTextField.shortcut.thousand", new Integer(3));
                addShortcut(messageSourceAccessor, "BigDecimalTextField.shortcut.million", new Integer(6));
                addShortcut(messageSourceAccessor, "BigDecimalTextField.shortcut.billion", new Integer(9));
                addShortcut(messageSourceAccessor, "BigDecimalTextField.shortcut.squillion", new Integer(0));
	            shortcutInitialised = true;
	        }
	    }
	}
    
    private static void addShortcut(final MessageSourceAccessor messageSourceAccessor, final String msgKey, final Integer offset) {
        try {
            SHORTCUTS.put(messageSourceAccessor.getMessage(msgKey), offset);
        }catch(final NoSuchMessageException e) {
            // do nothing
        }
    }

and finally a call to initialiseShortcut() in the main constructor.

I hope it is ok

Kind regards
Benoit.

>          Issue Type: Improvement
>          Components: Helper Classes

> We would like to be able to add shortcuts, like "3m" meaning 3 millions, 2k = 2,000. Typically a shortcut for hundred, thousand, millions, billions (for SocGen J ).
> Unfortunately, BigDecimalTextField is explicitly instantiated in several places, making it impossible to extend.
> We have a patch that works fine for us and it should work internationally as the shortcut may vary from one language to the other.
> One needs to add the shortcut characters in a messages.properties file:
> BigDecimalTextField.shortcut.hundred=h
> BigDecimalTextField.shortcut.thousand=k
> BigDecimalTextField.shortcut.million=m
> BigDecimalTextField.shortcut.billion=b
> ...
> So if you type 3k in the field, it will immediately be replaced by 3000.
> If you do not have those entries in the messages.properties, it won't use shortcuts so it is transparent if you do not want it.
> I hope that the patch will be accepted so that we can use SpringRC straight out of the box...
> Many thanks
> Benoit
