Hi,
Create an interface, like:
public interface HasState {
void setEnabled(boolean enabled);
boolean isEnabled();
}
...and then implement this with your composite widget. And don't try
to cast objects, GWT supports 'instanceof'. :-)
I hope this was to any help.
P.s. I'm actually confused that such an interface doesn't already
exist within the GWT API since many widgets have exactly those two
methods.
