Hi All,

What is meant by a control is wrapped. What is meant by being wrapped. I know that wrapper classes are used for making primitive types into classes.

But what is meant by using it in reference to controls.

Thanks

It means the control is in a container. So a text control will be in a container object.

i know that a control is in a container.

But in documentation its written that :-

"_The ALV Grid Control is a special case as it uses a control that is already wrapped_"

Is does mean that Alv grid control is encapsulated in- CL_GUI_ALV_GRID.

Thanks
