I'd like to get some thoughts around adding the following to the base
Component class.
I may have missed something and it's already available via some other
elegant means :)
add(new Label("testLabel", getString(dashboardModel.getNameKey(),
DashboardTestModel.class, "default val")));
It's sort of a convience method that would get used in panels, forms, pages
etc. and would allow any class to have its appopriate translations written
in property files next to the class.
At the moment I have it in an abstract DashboardPanel, but I'd like to
expose it to all components, and I think it could be useful for others.
(I can of course put it into some Util thing, but it makes it less handy,
and every impl a bit less elegant.)
What are your thoughts?
/**
* @param key The resource key
* @param clazz The class
*
* @return the resolved string, or null if it cannot be found.
*/
public String getString(final String key, final Class clazz) {
return getString(key, clazz, null);
}
/**
* @param key The resource key
* @param clazz The class
* @param defaultValue A default value if the string cannot be found
*
* @return the resolved string, or null if it cannot be found.
*/
public String getString(final String key, final Class clazz, final
String defaultValue) {
final IResourceSettings resourceSettings =
Application.get().getResourceSettings();
String string = null;
for (Object o : resourceSettings.getStringResourceLoaders()) {
IStringResourceLoader loader = (IStringResourceLoader) o;
string = loader.loadStringResource(clazz, key, getLocale(),
getStyle());
if (string != null) {
break;
}
}
return (string != null) ? string : defaultValue;
}
