I see the doc and it said > *AbstractCell<http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/cell/client/AbstractCell.html#AbstractCell%28java.lang.String...%29> > *(java.lang.String... consumedEvents) > Construct a new > AbstractCell<http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/cell/client/AbstractCell.html>with > the specified consumed events. and I already pass "click" and "keydown" in the constructor. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
