Hi Chris,
Actually jquery ui's selectable provides the ability to prevent their
events to be fired. The option is "cancel" [1]
So, as I was testing, here is the full code to manage your "remove" button:
CSS
<style type="text/css">
.sortable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
.sortable li { margin: 0.3em; padding: 0.3em; font-size: 1.1em;
background-color: #fff; }
.sortable li .ui-icon { position: absolute; }
.sortable li .item { margin-left: 1.3em; }
.ui-selectable .ui-selecting { background: #FECA40; }
.ui-selectable .ui-selected { background: #F39814; color: white;
}
</style>
HTML
<ul wicket:id="sortable" class="sortable">
<li wicket:id="items">
<span wicket:id="icon" class="handle">[icon]</span>
<div wicket:id="container">
<span wicket:id="item" class="item">[label]</span>
<a wicket:id="remove">remove</a>
</div>
</li>
</ul>
<br/>
<div wicket:id="feedback" style="width: 60%;"></div>
JAVA
public MyPage extends WebPage()
{
// FeedbackPanel //
this.feedback = new JQueryFeedbackPanel("feedback");
this.add(this.feedback.setOutputMarkupId(true));
// Sortable //
final MySortable sortable = new MySortable("sortable", list, new
Options("handle", Options.asString(".handle")));
this.add(sortable);
}
class MySortable extends Sortable<String> {
public MySortable(String id, List<String> list, Options options)
{
super(id, list, options);
}
@Override
protected void onInitialize()
{
super.onInitialize();
this.add(new
SelectableBehavior<String>(JQueryWidget.getSelector(this), new
Options("cancel", Options.asString(".handle"))) {
private static final long serialVersionUID = 1L;
@Override
protected String getItemSelector()
{
return "li";
}
@Override
protected List<String> getItemList()
{
return list;
}
@Override
public void onConfigure(Component component)
{
super.onConfigure(component);
// this is the option to prevent events to be fired (on
A-link)
this.setOption("cancel", Options.asString("a"));
}
@Override
public void onSelect(AjaxRequestTarget target, List<String>
items)
{
info("selected " + items);
target.add(feedback);
}
});
}
@Override
protected HashListView<String> newListView(IModel<List<String>> model)
{
return new HashListView<String>("items", model) {
@Override
protected void populateItem(final ListItem<String> item)
{
item.add(new
EmptyPanel("icon").add(AttributeModifier.append("class", "ui-icon " +
JQueryIcon.ARROW_2_N_S)));
item.add(AttributeModifier.append("class",
"ui-state-default"));
WebMarkupContainer container = new
WebMarkupContainer("container");
item.add(container);
container.add(new Label("item", item.getModelObject()));
container.add(new AjaxLink<Void>("remove") {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target)
{
String removedItem = item.getModelObject();
MySortable.this.onRemove(target, removedItem);
MySortable.this.info("removed " + removedItem);
target.add(feedback);
target.add(MySortable.this);
}
});
}
};
}
@Override
public void onUpdate(AjaxRequestTarget target, String item, int index)
{
super.onUpdate(target, item, index);
this.info("The list order is now: " + this.getModelObject());
target.add(feedback);
}
}
Hope this helps,
Sebastien
