This post on the GWT mailing list describes an alternative solution. You have to create a new ClientBundle
which references your CSS file:
import com.google.gwt.core.client.GWT;
import com.google.gwt.resources.client.ClientBundle;
import com.google.gwt.resources.client.CssResource;
public interface Resources extends ClientBundle {
public static final Resources INSTANCE = GWT.create(Resources.class);
@Source("style.css")
@CssResource.NotStrict
CssResource css();
}
And then inside your onModuleLoad()
method you have to inject the CSS file:
public class YourApp implements EntryPoint {
public void onModuleLoad() {
//...
Resources.INSTANCE.css().ensureInjected();
//...
}
In my opinion this is the cleanest and easiest way to override the styles.
