Class Searchbox<E>

  • Type Parameters:
    E - Element type in model
    All Implemented Interfaces:, java.lang.Cloneable, Component, Disable, Scope, ComponentCtrl

    public class Searchbox<E>
    extends HtmlBasedComponent
    implements Disable
    A dropdown list that allows users to search and select items.

    Available in ZK EE.

    Default getZclass(): z-searchbox.

    Events: onOpen, onSelect, onSearching, onAfterRender

    Besides assign a list model, you could assign a renderer (a ItemRenderer instance) to a searchbox, such that the searchbox will use this renderer to render the data returned by ListModel.getElementAt(int). If not assigned, the default renderer, which assumes a label per item, is used.

      • getModel

        public ListModel<E> getModel()
        Returns the model associated with this searchbox, or null if this searchbox is not associated with any list data model.
      • setModel

        public void setModel​(ListModel<E> model)
        Sets the list model associated with this searchbox.
        model - the list model to associate, or null to dis-associate any previous model. If not null, it must implement Selectable.

      • onInitRender

        public void onInitRender()
        Handles a private event, onInitRender. It is used only for implementation, and you rarely need to invoke it explicitly.
      • getItemRenderer

        public ItemRenderer<E> getItemRenderer()
        Returns the renderer to render each item, or null if the default renderer is used.
      • setItemRenderer

        public void setItemRenderer​(ItemRenderer<E> renderer)
        Sets the renderer which is used to render each item if getModel() is not null.

        Note: changing a render will cause the searchbox to re-render.

        renderer - the renderer, or null to use the default.
      • setItemRenderer

                             throws java.lang.ReflectiveOperationException
        Sets the renderer by use of a class name. It creates an instance automatically.
        clsnm - The class name
        java.lang.ReflectiveOperationException - if failed to initialize the renderer

        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.
