I have a log in page which asks username and password to log in for
students or teachers. After confirmation the informations of students
or teachers, i would like to redirect user to his proper page (i mean
change the log-in page to his proper page) , basicly i didn't
understand how can i do that after clicking the "CONFIRM" button.
I am myself a beginner, although I "play" with GWT for some months already (doing proof of
concept, prototypes, etc., exploring the capabilities). So I hope I won't be misleading.
My understanding is that in GWT, you don't really have the concept of "pages" like you do
in classical Web sites / applications.
Everything happens at the same URL, in the same page, mostly empty: it is filled by
JavaScript, using Ajax to fetch the data and which components to display.
So, once the login is validated, you have to fill this page with the main UI:
something like
RootPanel.get().clear();
RootPanel.get().add(new MainUI());
(or with RootLayoutPanel, of course).
An alternative is to use the MVP pattern (with a library like GWT-Platform, MVP4G, the
official Google support, or similar) which manages the concept of pages for you.
