Instead, it's meant to be used when developing the code or when the interface - changes. - - The adaptor classes generated by \c dbusidl2cpp are just a skeleton that must be completed. It - generates, by default, calls to slots with the same name on the object the adaptor is attached - to. However, you may modify those slots or the property accessor functions to suit your needs. -*/ |
