Re: DecimalFormatLabel (proposed)
In my opinion, it could be more usefull to nest a StringResourceModel
directly in a "ResourceLabel", as formating number is often application wide
and sometimes Locale dependent. And it covers more use case. It's just my
point of view.
Maybe like this :
protected void onComponentTagBody(final MarkupStream markupStream, final
ComponentTag openTag)
{
replaceComponentTagBody(markupStream, openTag, new
StringResourceModel(formatKey, this, getDefaultModel(), new
Object[]{getDefaultModelObject()}, defaultValue));
}

Re: DecimalFormatLabel (proposed)
Or we go one step further back. I think this would handle all use cases. If
we want to put in a NumberFormat or a DecimalFormat , in both cases it
should work.
public class FormattedLabel extends Label{
final private Format formatter;
public FormattedLabel(String id, IModel model, Format
format) {
super(id, model);
formatter = format;
}
public FormattedLabel(String id, Number obj, Format format) {
this(id, new Model(obj), format);
}
public FormattedLabel(String id, Format format) {
super(id);
formatter = format;
}
/**

@Override
public void onComponentTagBody(final MarkupStream markupStream, final
ComponentTag openTag) {
String response;
try {
response = formatter.format(getDefaultModelObject());
} catch (IllegalArgumentException ex) {
error(getString("Format"));
response = "";
} catch (NullPointerException ex) {

response = "";

Re: DecimalFormatLabel (proposed)
Yes, you're right, but this way fit 90% of my needs (It's a Label...)
Otherwise, it's possible to use a CustomConverter to do it, and then
override getConverter on Component. So, it also work on TextField (but i
agree, it's not exactly your use case. ) :
@Override
public IConverter getConverter(Class type) {
return PercentConverter.INSTANCE_2DEC;
}
public class PercentConverter extends AbstractNumberConverter {
public static final PercentConverter INSTANCE = new PercentConverter();
public static final PercentConverter INSTANCE_2DEC = new
PercentConverter() {
public NumberFormat getNumberFormat(Locale locale) {
NumberFormat nf = DecimalFormat.getPercentInstance(locale);
nf.setMinimumFractionDigits(2);
nf.setMaximumFractionDigits(2);
return nf;
};
};
public static final PercentConverter INSTANCE_4DEC = new
PercentConverter() {
public NumberFormat getNumberFormat(Locale locale) {
NumberFormat nf = DecimalFormat.getPercentInstance(locale);
nf.setMinimumFractionDigits(4);
nf.setMaximumFractionDigits(4);
return nf;
};
};
public Object convertToObject(String value, Locale locale) {
if (value == null)
return null;
value = value.trim();
if (value.trim().equals(""))
{
return null;
}
Number n = null;
try {
n = getNumberFormat(locale).parse(value);
} catch (ParseException e) {
throw newConversionException(e.getMessage(), value,
locale).setFormat(
getNumberFormat(locale));
}
return n.floatValue();
}
@Override
protected Class getTargetType() {
return Float.class;
}
@Override
public NumberFormat getNumberFormat(Locale locale) {
return NumberFormat.getPercentInstance(locale);
}
}

RE: DecimalFormatLabel (proposed)
Suppose someone wants to call formatlLabel.getModelObject() ...
I don’t see why they would, but hypothetically.
In this case you would get the formatted string. Since the label is merely a
view, should it be changing the model even by formatting it?

RE: DecimalFormatLabel (proposed)
I figured this would work best if we use things like CompoundPropertyModel.
Imagine you have a property of type int called myInt in POJO called myPojo
Then the code becomes extremely simple
WebMarkupContainer container = new WebMarkupContainer("container", new
CompoundPropertyModel(myPojo));
container.add(new DecimalFormatLabel("myInt", new DecimalFormat());

Looking over the sourcecode of DecimalFormat (Java 6) there are a few fields which do not implements Serializable. Those are all of type DigitList and FieldPosition. however, in all the cases they are marked as Transient, so they shouldnt interfere with the serialization? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/DecimalFormatLabel-proposed-tp3834813p3834903.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
