Adobe Illustrator SDK

HI,

          I am developing an adobe illustrator mac os plugin. there is a sample plugin called Empty Panel in the SDK.

1-I need to call the calculator Xib from one of the Barcontroller's button actions, how is it possible?

2- The Barcontroller Xib files are objective C files with .h and .mm extensions. i need to call c++ function from EmpltypnalePlugin.cpp in barcontroller.mm file. i have tried many options to call different C++ functions but in barcontroller.mm file, I get error that "function" is private member of EmptyPanelPlugin class.

in barcontroller.mm file almost all the functions from EmptypanelPlugin.CPP  are strikethrough with a red line.
