HasClickHandler interface

[jorel]

in order to decouple presenter from view in MVP (see example here http://code.google.com/webtoolkit/do...itecture.html), the HasClickHandler interface was implemented by com.google.gwt.user.client.ui.Button widget. Thus, you can then have, in your presenter, a 'Display' interface that has methods like 'getAddButton' which returns a 'HasClickHandlers' interface. This allows the presenter to not be dependent on the view implementation but still be able to register a click handler callback on a button.

Can this interface be added to smartGWT buttons, etc?



I just found that SmartGWT has Button class implementing 'HasIconClickHandlers' which is similar to 'HasClickHandlers' .
So, perhaps a more general question would be: Are the best practices like MVP, DI, EventBus, History and others documented and possibly demonstrated in SmartGWT sample code?

I'm wondering the same. It's weird because the javadoc says it does implement the HasClickHandlers interface.

Link to IButton javadoc: http://www.smartclient.com/smartgwt/javadoc/com/smartgwt/client/widgets/IButton.html

I'm using SmartGWT 2.2 found at http://code.google.com/p/smartgwt/

Oops, the errors I was encountering were because I imported the HasClickHandlers class from com.google.gwt.event.dom.client instead of the one from com.smartgwt.client.widgets.events.
