Examples of org.zkoss.zk.ui.Component.invalidate()

org.zkoss.zk.ui.Component.invalidate()

Invalidates this component by setting the dirty flag such that it will be redraw the whole content of this component and its dependences later. And, the widget associated with this component and all its descendant at the client will be deleted and recreated, too.

If the application is totally controlled by the server side (i.e., you don't write client codes), you rarely need to access this method.

It can be called only in the request-processing and event-processing phases. However, it is NOT allowed in the rendering phase.

    return "zhtml.Text";
  }
  public void setParent(Component parent) {
    final Component old = getParent();
    if (old != null && old != parent && !isIdRequired())
      old.invalidate();


    super.setParent(parent);


    if (parent != null && old != parent && !isIdRequired())
      parent.invalidate();
