interface Display {
HasClickHandlers getSaveButton();
HasClickHandlers getCancelButton();
HasValue<String> getNumberField();
HasValue<String> getLabelPicker();
}
This will work for this example at least. If you want to bind events
AND set a value to those fields you'd need to combine the two
interfaces in a new one, or perhaps have two accessor methods.
