Radio Button Value Constants

These constants specify the value of a standard radio button control and are passed in the newValue parameter of SetControlValue and are returned by GetControlValue . The radio button value constants are changed with Appearance Manager 1.0 to support mixed-value radio buttons.



 
enum {

    kControlRadioButtonUncheckedValue   = 0,

    kControlRadioButtonCheckedValue     = 1,

    kControlRadioButtonMixedValue       = 2

};

Constant descriptions

kControlRadioButtonUncheckedValue: The radio button is unselected.
kControlRadioButtonCheckedValue: The radio button is selected.
kControlRadioButtonMixedValue: Mixed value. Indicates that a setting is on for some elements in a selection and off for others. This state only applies to standard Appearance-compliant radio buttons.
