ZK Frame Note 5, event

    The event is the Org.zkoss.zk.ui.event.Event class, which notifies the application what is going on. Each type of event is represented by a specific class.
    to respond to an event, the application must register one or more event listeners for the event. There are 3 ways to be a component event listener.
(1) The OnXxx event listener is generally developed as an attribute of the component, as an event listener defined by the property.

<title= "Hello"  border= "normal">    < label = "Say hello"  onClick= "alert (&quto;   Hello world!&quot;) "/></window>

(2)define the OnXxx () method in the associated build class as the event handler for the method definition.

1 <windowtitle= "Hello"Border= "normal">2  　　 <Zscript>3  　　　　 class MyButton extends button{4  　　　　　　 Public void OnClick (MouseEvent event) {5  　　　　　　　　 MessageBox.Show ("Hello world!");6  　　　　　　 }7  　　　　 }8  　　 </Zscript>9  　　 <ButtonID= "Hellobtn"label= "Say hello!" />Ten </window>

(3) Add the Aaeventlistener () method to the component or page as the time processor for the new listener

<windowtitle= "Hello"Border= "normal"> 　　 <ButtonID= "Hellobtn"label= "Say Hi" /> 　　 <Zscript>Hellobtn.addeventlistener ("OnClick", new Org.zkoss.zk.ui.event.EventListener () {public void OnEvent (event eve　　　　NT) {MessageBox.Show ("Hello world!"); }})</Zscript></window>
