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
};
