thanks for the link
I see the link and see a type of panel called FormPanel, I also see something about GWT-RPC.
I think if one of the right panel is let user fill in some searching criteria, and when the user click on the submit button,
the searching criteria will pass to server, and in the server will run a sql to retrieve the result, and then return to another panel to show the record retrieved.
in this case, need use FormPanel?
then when submit, the parameter is passed to server, but how the server get that parameter? just use request.getParameter("XXX")?
then how to return result to other panel to show the reult?
and how this related to GWT-RPC?
I am very new in GWT and always found the references is only for one page (no jump page like the above scenario).
I think, if GWT-RPC for ajax partial refresh, for whole page refresh like my example (jump page from search criteria to result), then use formpanel and traditional request.getParameter, request.sendDispatcher?
