**1.父窗体中打开子窗体，参考代码：** ~~~Java IUIWindow uiWindow = null; UIContext uiContext = new UIContext(this); uiContext.put("Owner", this); uiWindow = UIFactory.createUIFactory("com.kingdee.eas.base.uiframe.client.UIModelDialogFactory").create( "需要打开的UI界面的类路径", uiContext,null,OprtState.VIEW); uiWindow.show(); ~~~ **2.在子窗体中获取父窗体传递的参数:** ~~~java 父UI data = (父UI)this.getUIContext().get("Owner"); ~~~ **3.在子窗体中 关闭本窗体：** ~~~Java this.disposeUIWindow(); ~~~
