8.1.1    OVS

接口:IWDOVSDialog、IWDOVSSuggester、IWDOVSController、IWDOVSProvider、IWDWindow、IWDExternalControllerInterface、IWDComponentUsage
			

 

 

可将context中的属性的数据类型直接设置为某个JAVA类,如在context中创建一个dialog的属性, 并将该属性的数据类型设为com.sap.tc.webdynpro.progmodel.api.IWDOVSDialog,表示该属性可实现对话框的打开、关闭等操作。

其中IWDOVSController传递给IWDOVSDialog、IWDOVSSuggester,用于控制dialog与web dynpor的数据通讯

 

IWDOVSProvider Web Dynpro uses this interface to get a component handling the OVS. Web Dynpro only needs the interface window of this component to supply the popup window
