Hi,
I think what is missing you is the AjaxBehavior / Event / jQuery event
binding.
Basically, your ContextMenuBehavior (CMB) should embed an ajax behavior
(JQueryAjaxBehavior, let's say AB). A common Event object (E) should be
shared between CMB & AB. Note that CMB should implement IJQueryAjaxAware
the its instance (this) should be passed to AB's contructor.
Once bound to the CMB (see #bind() ), you can get the
AB#getCallbackFunction() (if using wicket-jquery-ui-6.x) that you will
transmit to the jQuery function 'callback' like this:
"{ selector: '.the selector', callback: " + ab.getCallbackFunction() + " }".
At this stage, AB should be invoked when the jQuery event is fired, and you
can do things in CMD#onAjax(AjaxRequestTarget target, JQueryEvent event).
(note the JQueryEvent here)
The question is now how you transmit an additional information to AB (means
wicket side).
First, you need to know what parameter context-menu will give you when the
callback is triggered. If I see that the callback have 2 parameters (key
and options), I will suppose that the key is the menu-id I am interested to
get back, so in AB:
protected CallbackParameter[] getCallbackParameters()
{
return new CallbackParameter[] {
CallbackParameter.explicit("key") //considering key is the
menu-item key, see CallbackParameter javadoc
CallbackParameter.context("option"),
};
}
Once invoked AB will create a new E. What you need is a custom event that
have a key property (ie: getKey()) which have the value coming the jquery
callback:
protected static class MyCallbackEvent extends JQueryEvent
{
private final String key;
public MyCallbackEvent()
{
this.key =
RequestCycleUtils.getQueryParameterValue("key").toString(); //the menu key!
}
public String getKey()
{
return this.key;
}
}
Here we are, in the onAjax above, get the key, eventually the menu-item
associated to the key, and fire a custom event (for instance onClick,
onMenuClicked, onWhatYouWant)
if (event instanceof MyCallbackEvent )
{
String key = ((MyCallbackEvent)event).getKey();
MenuItem item = null; // FIXME: get the menu item using the key from
the List<MenuItem>
this.onClick(target, item); //the custom event
}
If you encounter other problem(s), you can post a quickstart on the
wicket-jquery-ui googlegroup. (but my home PC is currently under
re-installation so feel free to investigate a little bit on your own
before... ;))
Best regards,
Sebastien.
