Twitter

Twitter Project

The Twitter library contains wicket components and behaviors to use the Twitter widgets with wicket.

Buttons

There are two button types:

• Tweet
• Follow

You can find some examples here: https://twitter.com/about/resources/buttons

These components can be used like normal wicket components. It is required to use a link-tag (a) for the markup. The components should contain the major attributes documented on dev.twitter.com. It is possible to set the properties in the markup as well. They just get overridden if the property is set in at the java component too.

Button Example

		final FollowButton button = new FollowButton("followButton", "tfreier");
		button.setShowFollowerCount(true);
		add(button);

		<a wicket:id="followButton"> </a>

Web Intents

Web intents are links to twitter to perform actions on twitter. https://dev.twitter.com/docs/intents

Follow Link Example

		final FollowLink link = new FollowLink("link");
		link.setScreenName("tfreier");
		add(link);

		<a wicket:id="link">follow me</a>

Behaviors

The anywhere behaviors add some behaviors to normal components like a label. https://dev.twitter.com/docs/anywhere/welcome

LinkifyBehavior

The LinkifyBehavior links all words beginning with @ to the matching twitter-account.

		final Label label = new Label("label", "This is a linkify test by @tfreier");
		label.add(new LinkifyBehavior("your api key"));

		add(label);

		<span wicket:id="label"></span>

HovercardBehavior

The HovercardBehavior creates hover cards for any twitter account mentions beginning with an @.

		final Label label = new Label("label", "This is a hovercard test by @tfreier");
		label.add(new HovercardBehavior("your api key"));

		add(label);

		<span wicket:id="label"></span>

Event Behaviors

Event Behaviors are basically ajax callbacks for events caused by web intents. https://dev.twitter.com/docs/intents/events

Follow Event Example

		final IModel<String> responseModel = Model.of();

		final FollowLink link = new FollowLink("link");
		link.setScreenName("tfreier");

		add(link);

		final Label label = new Label("resonse", responseModel);
		label.setOutputMarkupId(true);
		add(label);

		add(new AjaxFollowEventBehavior()
		{
			@Override
			protected void onEvent(final AjaxRequestTarget target, final Event event)
			{
				responseModel.setObject("followed");
				target.add(label);
			}
		});

		<a wicket:id="link">follow</a>
