ZK:关闭子窗口时刷新父窗口

Question

我想在ZK中实现在关闭子窗口的同时刷新父窗口。

Parent.zul - 它有一个下拉列表和一个按钮(标签为“添加到下拉列表”)，用于向该下拉列表添加值。单击此按钮时，它应该打开一个子窗口，其中包含在下拉列表中输入文本的选项。

child.zul:它有一个用于输入下拉列表值的文本框和一个“关闭”按钮。单击关闭按钮时，它应该关闭子窗口并刷新父窗口中的下拉列表。

预先感谢您的意见。

================================================== ===========================

父级:sock.zul

<window id="sockWindow" title="New Sock" width="600px" apply="SockController" mode="modal" closable="true">
    <div align="left" style="float: left;" >    
        <button id="btnLookup" label="Manage Lookup" width="150px"/>
    </div>    
</window>

sockController.java: 公共(public)类 SockController 扩展了 SelectorComposer {

@Listen("onClick = button#btnLookup")
public void onClickAdd() throws Exception {
    showPopup(new EventListener<Event>() {
        @Override
        public void onEvent(final Event event) throws Exception {
            Object someData = event.getData(); // cast to whatever object you expect to give.   
            //Make your refresh code here.                
        }
    });          

}   

public static void showPopup(final EventListener<Event> eventListener)
    throws InterruptedException {
//you can give more params with the method to add them as arguments.
    Map arguments = new HashMap<String, String>();
    arguments.put("source", "parent.zul");
  //  arguments.put("hid", hwid.toString());
  //  arguments.put("displaymode", displaymode);

    openModal("/managelookup.zul",null, arguments, eventListener);
}

public static void openModal(final String page, final Component parent,
    final Map<String, Object> obMap,
    final EventListener<Event> onCloseListener)
    throws InterruptedException {
    for (final Map.Entry<String, Object> entry : obMap.entrySet()) {
        Executions.getCurrent().setAttribute(entry.getKey(),
            entry.getValue());
    }
    Executions.getCurrent().setAttribute(Composition.PARENT, null);
    final Component createComponents = Executions.createComponents(page,
            parent, obMap);
    Component parent1 = createComponents;
    parent1 = getWindow(parent1);
    if (parent1 instanceof Window) {
        final Window window = (Window) parent1;
        if (onCloseListener != null) {
            //attach the listener so when popup is closed the listener is called.
            window.addEventListener(Events.ON_CLOSE, onCloseListener);
            window.addEventListener(Events.ON_CANCEL, onCloseListener);
        }
        window.doModal();
    }
}  

}

子:managelookup.zul:

        <button id="cancel" label="Close"/>
</window>

ManageLookupsController.java: public ManageLookupsController() 抛出异常{

@Listen("onClick = button#cancel")
public void onClickCancel() {

    manageLookup.setVisible(false);
    manageLookup.detach();
    Events.postEvent(Events.ON_CLOSE, windowOrSpaceOwner, someData);
}    

}

我将在这里向您展示我们应用程序的一些示例:

在父 Composer 中，我们打开弹出窗口并为回调提供一个事件监听器:

public void onActionShowPopup () {
    showPopup(new EventListener<Event>() {
            @Override
            public void onEvent(final Event event) throws Exception {
                Object someData = event.getData(); // cast to whatever object you expect to give.   
                //Make your refresh code here.                
            }
        });  
}

public static void showPopup(final EventListener<Event> eventListener)
        throws InterruptedException {
    //you can give more params with the method to add them as arguments.
    final Map<String, Object> args = new HashMap<>();
    args.put("modus", "modal");
    openModal("/WEB-INF/webpages/zk/popup/some_popup.zul",null, args, eventListener);
}

public static void openModal(final String page, final Component parent,
        final Map<String, Object> obMap,
        final EventListener<Event> onCloseListener)
        throws InterruptedException {
    for (final Map.Entry<String, Object> entry : obMap.entrySet()) {
        Executions.getCurrent().setAttribute(entry.getKey(),
                entry.getValue());
    }
    Executions.getCurrent().setAttribute(Composition.PARENT, null);
    final Component createComponents = Executions.createComponents(page,
            parent, obMap);
    Component parent1 = createComponents;
    parent1 = getWindow(parent1);
    if (parent1 instanceof Window) {
        final Window window = (Window) parent1;
        if (onCloseListener != null) {
            //attach the listener so when popup is closed the listener is called.
            window.addEventListener(Events.ON_CLOSE, onCloseListener);
            window.addEventListener(Events.ON_CANCEL, onCloseListener);
        }
        window.doModal();
    }
}

public Component getWindow (Component comp) {
    if (comp != null && !comp instanceof Window) {
        return getWindow(comp.getParent());
    }
    return comp;
}

当然，当你关闭时，在弹出窗口中:

 Events.postEvent(Events.ON_CLOSE, windowOrSpaceOwner, someData);

我创建了a fiddle使用此代码及其工作位置。
也许你能看到哪里出错了？

希望这能有所帮助。
