The content of the Tab widget is presented by using TabPanel widget. The TabPanel widget loads the content in one of 2 ways. The method depends on whether the TabPanel has been used as a container or not. If it has been used as a container, then the details for which data should be displayed need to be described in the TabPanel itself.
If the TabPanel hasn't been used as a container then it is necessary to specify a macro, which is used in the refresh. This method is considerable faster and is recommended where possible.
