[Wicket-user] ListView for navigation menu?

Tue, 01 Nov 2005 12:35:54 -0800

<>Hi all,


I'm a new user to Wicket. I love what I have seen so far. The HelloWorld example was very convincing for me to give Wicket a try!

I am trying to create a menu to go above my pages. I have been browsing through the Wiki and looked at the navigation example. The navigation example uses borders, but before I delve into those, I thought of trying something else, and I wonder if you could give me some feedback on it.

I thought I might use a ListView. I think I could add a ListView to my page that would contain Links to WebPages to create a simple navigation bar. I found some example code and HTML in the javadoc:

A ListView holds ListItem children. Items can be re-ordered and deleted, either one at a time or many at a time.

Example: 

          <tbody>
            <tr wicket:id="rows" class="even">
                <td><span wicket:id="id">Test ID</span></td>
            ...

Though this example is about a HTML table, ListView is not at all limited to HTML tables. Any kind of list can be rendered using ListView.

And the related Java code: 

 add(new ListView("rows", listData)
 {
 	public void populateItem(final ListItem item)
 	{
 		final UserDetails user = (UserDetails)item.getModelObject();
 		item.add(new Label("id", user.getId()));
 	}
 });

For a navigation bar I could think of this for the HTML:

<div id="navigation">
	<span class="item" wicket:id="navigationitems">
		<a wicket:id="link" href="">Item</a>
		<span class="separator"> | </span>
	</span>
</div>

But I need some way to identify the last separator in the stylesheet, so I can hide it. In the example the class "even" is used in the table row, but how is this updated to "odd" ?

Am I on the right track here? Any suggestions,

Greetings,

-Stijn
