Hello -
So, I've got a composite that has something like this inside it...
private HandlerManager changeHandlers = new HandlerManager( null );
public HandlerRegistration addValueChangeHandler(ValueChangeHandler
handler)
{ return changeHandlers.addHandler(ValueChangeEvent.getType(),
handler); }
...and somewhere down the pipeline, I want to actually fire off an
event to anyone who registered a handler when the composite decides
it's represented value has changed and wants the rest of the world to
know. However, the syntax for actually constructing and firing the
event off has got me pulling my hair out.
I've tried variants of sending the event through the change
handlers...
changeHandlers.fireEvent( new ValueChangeEvent("foo") );
changeHandlers.fireEvent( new ValueChangeEvent<String>("foo") );
...and using the static fire() method in the event class itself...
ValueChangeEvent<String>.fire( changeHandlers, "foo");
...and Eclipse complains loudly about all of these constructions. I
mean, I know this can't be that hard, but I can't find any good
examples of things like this using the new (GWT 1.6 or later) event
handlers, and reading the code sends me down a DOM event/Java generics
rabbit hole that I'm frankly not experienced enough to deal with
yet...
Any help appreciated!
Jim
