createRadioButton

Description

Creates a radio button user control on the user window specified by windowID. A radio button is similar to a check box, except that its checked value is mutually exclusive with other radio buttons. Thus, if one radio button gets checked, the other radio buttons in the group automatically uncheck.

The control is initially placed in the top-left corner of the user window, and must be placed by using the -pos option, or by using the setControlPos command.

The command returns the control ID of the user control, which should be saved for later operations on the control.
