Mine is very simple, with 2 different views and buttons attached to each view that allow it to swith from one view to another. <br /><br />What would happen if one of the buttons didnt just switch the view, but did a RPC call, but some json data back to populate a table. How do I make the current view(composite) react to these?<br /><br />See im confused because the sample project the Handlers are registered to the mainpresenterImpl. How would I access the current presenters bound view's widgets to manipulate them?<br /><br />This kinda falls in line with Jeff and Kango's questions I think, and they didnt get answered.<br /><br />Please help.<br /><br />Sincerely,<br /><br />dave<br /><br />ps: Great work by the way.Unknownhttps://www.blogger.com/profile/06578622413537471674noreply@blogger.comtag:blogger.com,1999:blog-6234137978591823192.post-84519560953838042582009-11-18T09:46:03.970-08:002009-11-18T09:46:03.970-08:00Eduadro, have you had a look at this similar proje...Eduadro, have you had a look at this similar project?<br /><br />http://code.google.com/p/mvp4g/<br /><br />What do you think about it?<br /><br />ThanksUnknownhttps://www.blogger.com/profile/10176340007891585082noreply@blogger.comtag:blogger.com,1999:blog-6234137978591823192.post-739361702695223472009-10-22T20:21:29.958-07:002009-10-22T20:21:29.958-07:00Hello, everyone is interested in printable and rea...Hello, everyone is interested in printable and readable version of Google IO about MVP, please look <br />http://extgwt-mvp4g-gae.blogspot.com/2009/10/gwt-app-architecture-best-practices.htmlAraminoshttps://www.blogger.com/profile/03387932583803366505noreply@blogger.comtag:blogger.com,1999:blog-6234137978591823192.post-37834792740990563312009-09-10T17:04:28.709-07:002009-09-10T17:04:28.709-07:00Yes, thank you.

I have done most of my GUI-esque programming in JFace/SWT with eclipse plug-in programming. <br /><br />This lends itself to a certain level of granularity. For example the IssueDisplayWidget and IssueEditWidget are what may be compared to Views in the eclipse world. They are composite with some buttons, and one or more lower level widgets that map to some data.<br /><br />For the actual lower level components though there is still need for some MVC/MVP concern. For example I could add an IssueListWidget, a presenter, and events wired appropriately to display this new widget. The question I have is that if I were to have some buttons and a table - should I have IssueListWidget handle the eventBus interaction and just use regular old attached listeners to update between IssueListWidget and the underlying table? Or is there any need to make the table have its own presenter and events?<br /><br />I would be curious to hear thoughts on pros and cons on various ways this could be handled.Jeffhttps://www.blogger.com/profile/00265492481933843140noreply@blogger.comtag:blogger.com,1999:blog-6234137978591823192.post-22377740587665218812009-08-04T12:54:58.111-07:002009-08-04T12:54:58.111-07:00Chad,
