Checkbox Value Constants

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



 
enum {

    kControlCheckboxUncheckedValue  = 0,

    kControlCheckboxCheckedValue    = 1,

    kControlCheckboxMixedValue      = 2

};

Constant descriptions

kControlCheckboxUncheckedValue: The checkbox is unchecked.
kControlCheckboxCheckedValue: The checkbox is checked.
kControlCheckboxMixedValue: 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 checkboxes.
