This can be implemented in a better way. See source code for navigation in
wicket. But here is a simple example
// Create a panel
import java.util.LinkedList;
import java.util.List;
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.AjaxLink;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.list.ListItem;
import org.apache.wicket.markup.html.list.ListView;
import org.apache.wicket.markup.html.panel.Panel;
import org.apache.wicket.model.IModel;
import org.apache.wicket.model.LoadableDetachableModel;
public abstract class AlphabeticalPanel extends Panel{
private static final long serialVersionUID = 1L;
public AlphabeticalPanel(String id) {
super(id);
IModel<List<String>> alphabeticalModel = new
LoadableDetachableModel<List<String>>(){
private static final long serialVersionUID = 1L;
@Override
protected List<String> load() {
List<String> alphabet = new
LinkedList<String>();
char letter;
for(letter = 'A'; letter <= 'Z'; letter++) {
alphabet.add( "" + letter );
}
return alphabet;
}
};
ListView<String> alphabeticalView = new ListView<String>(
"alphabeticalView",alphabeticalModel ){
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(ListItem<String> item) {
final String character = item.getModelObject();
AjaxLink<Void> link = new AjaxLink<Void>(
"link" ){
private static final long
serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget
target) {
onCharacterClicked(character,target);
}
};
link.add( new Label( "character" , character ));
item.add( link );
}
};
add( alphabeticalView );
}
public abstract void onCharacterClicked( String character,
AjaxRequestTarget target );
}
// Add the panel to a page
add( new AlphabeticalPanel( "panel" ){
private static final long serialVersionUID = 1L;
@Override
public void onCharacterClicked(String
character,AjaxRequestTarget target)
{
// Here you get the char. Get the data from
database and add another
view with the data
}
});
