Discussion 解説

The printing system invokes this method to inform your custom pane that the value of a PPD option you claimed to support via the supportedPPDOptionKeys method has changed. Typically, this method is invoked if the user changes the value of a supported PPD option to resolve a conflict with the value of another option.

In this optional method, you can update any internal data you maintain for this PPD option.

Special Considerations 特別な注意事項

The printing system does not invoke this method in OS X v10.4.
