Question

I have been writing some basic code for an application I am designing. I have learned the basics and gotten some simple database connection working with RPC calls etc. What I need to do now and am completely lost (as I am traditionally a c# developer with windows forms).

In c# if I wanted a new form I would just create it, and then call the show method.

How does one create multiple pages in GWT, and switch between them?

Thanks in advance,
Chris

Answer 1

The simplest way would be to

1. Make a new java class (GwtHome.java, GwtHelp.java etc)
2. Extend these classes by using the Composite class
3. Make the equivalent of a Master Page and add it to the rootPanel as a class with the appropriate headers, menu, footer and Content Placeholder (Could be any of the AbsolutePanel, VerticalPanel, HorizontalPanel objects provided by the GWT Framework)
4. By clicking on the menu clear the Placeholder and add the appropriate object of GwtHome, GwtHelp etc.

After getting aquanted with the above procedure, you might want to break up the code in many files using a design pattern as suggested by Andrei.
