Interface WebWindowListener

  • All Known Implementing Classes:
    WebWindowAdapter
    public interface WebWindowListener
    A listener for WebWindowEvent's.

    This listener informs when a new window is opened, when the content of a window changes or when a window is closed.

    Caution: The WebClient creates (and opens) the initial window as part of the construction process. This implies, the initial window is already open at the time you attach this listener. Therefore you will receive no open event for this.
