Well, first let me tell yo that I am new to GWT myself. So, I might
not be right all the time. (But I have done and tested already what I
said earlier)
Now
--that means i require just a single EntryPoint class..! I am trying
to
--create my web app's main menu using a MenuBar, and a major area
below it
--will display the contents of each MenuItem.
Ok, you can do this by putting a MenuBar and SimplePanel in a
VerticalPanel and then adding VerticalPanel to RootPanel.
--Can i use multiple RootPanel's in my web app..? i read somewhere
that this
--is discouraged.
Don't know if it is really discouraged but you can do so. Design your
html page as you like and give id attribute for those elements that
you want to access as rootpanels. Now in code you can say
RootPanel elementRootPanel = RootPanel.get("idOfTheElement");
to get your hands on it.
--ok, i got wat you are saying over here. Why should these classes
extend
--Composite?
Well GWT has it's own class hierarchy and to make things work and to
enable GWT use your custom "Composite" component, you need to extend
it from Composite. You might extend it from Widget or Some Panel, but
Composite is recommended I guess.
--Can you use separate methods in the class to return the data.
I couldn't understand the question
--What is this last line doing?
The last line is in fact adding what ever you layedout to DOM.
--how do i add clickListener to MenuItems, i think i can only specify
--commands to perform.
Try looking into javadocs of GWT.
In the case of MenuItem, I can use Command for the same purpose.
MenuItem item = new MenuItem("Click Me", new Command() {
public void execute() {
// Do the navigation here
containerSimplePanel.setWidget(new SomeCompositeInheritedClass
());
}
});
Hope it helps
