Class ClickCallback<T>

java.lang.Object

com.threerings.gwt.util.ClickCallback<T>

All Implemented Interfaces:

AsyncCallback<T>

Direct Known Subclasses:

InputClickCallback

public abstract class ClickCallback<T>
extends Object
implements AsyncCallback<T>

Allows one to wire up a button and a service call into one concisely specified little chunk of code. Be sure to call super.onSuccess() and super.onFailure() if you override those methods so that they can automatically reenable the trigger button.

When using the ClickCallback on a Label, the callback automatically adds the style actionLabel to the label and removes the style when the label is disabled during the service call. This style should at a minimum add 'text-decoration: underline; cursor: hand' to the label to indicate to the user that it is clickable.
