本文整理了Java中org.zkoss.zul.Listbox.getModel()方法的一些代码示例，展示了Listbox.getModel()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Listbox.getModel()方法的具体详情如下：
包路径：org.zkoss.zul.Listbox
类名称：Listbox
方法名：getModel

Listbox.getModel介绍

[英]Returns the model associated with this list box, or null if this list box is not associated with any list data model.

Note: if #setModel(GroupsModel) was called with a groups model, this method returns an instance of ListModel encapsulating it.
[中]返回与此列表框关联的模型，如果此列表框未与任何列表数据模型关联，则返回null。
注意：如果使用组模型调用#setModel（GroupsModel），此方法将返回封装它的ListModel实例。
