Re: Multiple pages question
I'm trying to make a small app to log darts games. Basically, it should be possible to login with a user, register a new user, choose all the options for a new game and play that game. Playing the game means you just click the darts board on screen where you hit the board and the program calculates scores etc. The game page exists of a darts board and all the statistics. This is where I came up with my question because it is really hard to lay out these things in Java code. So I started searching for a possibility to load HTML (where the elements are layed out correctly) and work on the elements by getting them with RootPanel.get(...) instead of building the lay-out with panels in Java. Does this make it more clear what I'm trying to do? Also, how do I actually load HTML from the server into my app through Java?

Use GWT-RPC or RequestBuilder (both are very well described in the docs) to get your html. Use iframe or just an HTMLPanel to display it.

Re: Multiple pages question
The easiest way is just to have the html in the host html page in a div with display:none Inside that div, have all the elements you need for the page, add widgets to these elements with RootPanel.get(id).add(something); and set the enclosing div to visible = true when you want it to be displayed. The other pages for a small app like this can also be shown and hidden as required in their own divs in the same way. As Alex said, you can keep the (GWT) 'pages' in their own html file, fetch them, extract the part you need and put it in an HTMLPanel as required. It doesn't seem worth it to me in this scenario.

Re: Multiple pages question
I think that the issue that you're running into here is one of mindset. Web developers think in terms of pages but a Swing/MFC/thick client developers dont. GWT is kind of a bridge between the two. From what i've seen, the GWT way of doing things is to clear out the visible components and render your new components to give the user a different view. (like you said) Now is your question how can i create these two views in separate java files (which is an architecture question) or how can i separate widget (element) composition from Java which is almost a philosophical question because GWT (at least as far as i've seen) is not designed to operate that way. (which i believe is a design feature, not an oversight) One other fly in the ointment that you may not have stumbled into yet which will blow your mind at first is using the back button. There is lots of documentation out there on using GWT History and it's really a different way of thinking coming from a web developer perspective. ...if you are asking the architecture question, so far i havent seen much yet on best practices for organizing your classes and widgets but you should start by searching for 'GWT Custom widgets' and specifically checking out the Composite class. That should get your started in how you can organize and compose your various views. Disclaimer... I've only been using GWT for about a month now but i've been doing Swing/Visual C++/VB gui's for a long time and to me GWT fits as naturally as anything i've ever seen from a web framework perspective. But it is very different from Swing, Spring MVC, JSF and the like.
