我试图在单击前一行时隐藏/显示网格中的一行(从 Java 代码动态填充)。模拟一个简单的 MasterDetail 组件。我在 java 代码中获得了单击行的正确索引,但是更改行的可见性不起作用!谁能帮我解决这个问题,或者有类似的方法吗?
谢谢,普亚
这是 ZUL 的代码:
<?xml version="1.0" encoding="UTF-8"?>
<zk xmlns="http://www.zkoss.org/2005/zul">
<window id="callbackLogWindow"
apply="CallbackLogWindowComposer"
border="none" height="100%" width="100%"
xmlns:w="http://www.zkoss.org/2005/zk/client">
<grid id="callbackLogGrid" oddRowSclass="non-odd" height="100%">
<columns>
<column label="Logging Name" />
<column label="Status" />
<column label="DateTime" />
<column label="Subject" />
<column label="Replies" />
</columns>
<rows>
<zk forEach="${callbackLogWindow$composer.callbacks}">
<row sclass='${forEachStatus.index % 2 != 0 ? "z-grid-odd" : ""}'
onClick="callbackLogWindow$composer.toggleRow(self.index)">
<custom-attributes callback="${each}"/>
<cell><label value="${callback.loggingName}" /></cell>
<cell><label value="${callback.resolved}" /></cell>
<cell><label value="${callback.callbackTime}" /></cell>
<cell><label value="${callback.subject}" /></cell>
<cell><label value="${callback.resolvedItemCount}" /></cell>
</row>
<row sclass='${forEachStatus.index % 2 != 0 ? "z-grid-odd" : ""}'>
<cell colspan="5">
<include src="callbackItem.zul" callback="${each}"/>
</cell>
</row>
<row>
<custom-attributes callback="${each}"/>
<button onClick="callbackLogWindow$composer.saveCallbackItems(callback)">
Save
</button>
</row>
</zk>
</rows>
</grid>
</window>
</zk>
和控制器:
public class CallbackLogWindowComposer extends SelectorComposer<Window> {
@Inject private CallbackDao callbackDao;
@Wire Grid callbackLogGrid;
private List<Callback> callbacks = new ArrayList<Callback>();
@Override
public void doAfterCompose(Window window) throws Exception {
super.doAfterCompose(window);
}
public List<Callback> getCallbacks() {
callbacks = callbackDao.findAll();
return callbacks;
}
public void toggleRow(int i) {
Component row = callbackLogGrid.getRows().getChildren().get(i+1);
row.setVisible(row.isVisible());
callbackLogGrid.renderAll();
}
public void saveCallbackItems(Callback cb) {
callbackDao.saveInTransaction(cb);
}
}
