As Eelco mentioned, there are quite a few ways... I typically use delegation
for this sort of thing with a model that wraps another model. This way it
can be reused for a Label, dropdown, textfield, etc....
you could do then:
add(new Label<String>("myLabelID", new UpperCaseModel(new
PropertyModel(myObject, "myField"))));
With code like:
import org.apache.wicket.model.IModel;
public class UpperCaseModel implements IModel<String> {
private static final long serialVersionUID = 1L;
private final IModel<String> mNestedModel;
public UpperCaseModel(IModel<String> nestedModel) {
if (nestedModel == null) {
throw new IllegalArgumentException("parameter 'nestedModel' can
not be 'null'.");
}
mNestedModel = nestedModel;
}
public String getObject() {
String obj = mNestedModel.getObject();
return obj == null ? obj : obj.toUpperCase();;
}
public void setObject(String object) {
mNestedModel.setObject(object);
}
public void detach() {
mNestedModel.detach();
}
}
Hope this helps...
