HandleChangeControlValue

The system calls this virtual method when the control’s value changes.

Declaration

virtual kern_return_t HandleChangeControlValue(bool in_control_value);

Parameters

  • in_control_value:

    The Boolean value attempting to be set on the control.

Return Value

kIOReturnSuccess on success. Upon success the control’s value should be updated.

Discussion

The default implementation calls SetControlValue() and returns kIOReturnSuccess. Subclass and override this method to handle changes to this control value and return kIOReturnSuccess upon success.
