Examples of org.zkoss.zk.ui.sys.ComponentCtrl.redraw()

org.zkoss.zk.ui.sys.ComponentCtrl.redraw()
Render (aka., redraw) this component and all its descendants.
It is called in the redrawing phase by the kernel, so it is too late to call {@link Component#invalidate()}, {@link org.zkoss.zk.ui.AbstractComponent#smartUpdate}or {@link org.zkoss.zk.ui.AbstractComponent#response} in this method. @since 5.0.0

      super.redrawChildren(out);
    } else if (isVisible() && shallVisitTree(tree, this)) {
      if (shallRenderTree(tree)) {
        ComponentCtrl child = getTreerow();
        if (child != null)
          child.redraw(out);
      }
      boolean close = !isOpen();
      ComponentCtrl child = getTreechildren();
      if (child != null) {
        if (close) ((Component)child).setAttribute(Attributes.SHALL_RENDER_ITEM, Boolean.TRUE);
