This method is called when a new window needs to be created. <p> A particular <code>Browser</code> can be passed to the event.browser field to host the content of a new window. <p> A standalone system browser is used to host the new window if the event.required field value is false and if the event.browser field is left <code>null</code>. The event.required field is true on platforms that don't support a standalone system browser for new window requests. <p> The navigation is cancelled if the event.required field is set to true and the event.browser field is left <code>null</code>. <p> <p>The following fields in the <code>WindowEvent</code> apply: <ul> <li>(in/out) required true if the platform requires the user to provide a <code>Browser</code> to handle the new window or false otherwise. <li>(out) browser the new <code>Browser</code> that will host the content of the new window. <li>(in) widget the <code>Browser</code> that is requesting to open a new window </ul>
This listener interface may be implemented in order to receive a {@link WindowEvent} notification when a new {@link Browser} needs to be provided by the application.
