Figure 1 describes the scenario. The first scenario deals with grouping the radio button within a column. Our second scenario handles just the opposite: we must group the radio buttons inside a row.

The form might contain text boxes, check boxes, radio buttons, and other widgets. You use the ButtonGroup class to group all radio buttons that need single selection.

Use the radio buttons to change the behavior of the submit button. For instance, when "close program" is selected, submit will exit the program.
