Hi, I can suggest the following solution for using Qt's "signal-slot" with an mitk interactor. It's maybe not the coolest solution, but it is the one that works.
First of all, the interactor should be placed locally in the directory where your functionality is. Otherwise "#include <qobject.h>" will fail (why? Maybe you know?). Than the interactor shouldn't have "MITK_CORE_EXPORT" makro, cause it's not a part of CORE any more. The interactor has to be derived from QObject and have "Q_OBJECT" in its declaration - just a usual procedure for using "signal-slot". Now you have to make sure, the corresponding meta object compiler file (moc) will be also created. To do so, just insert the line "your_ineractor_name".h into the "files.cmake" file of your functionality in the "SET( MOC_H_FILES" section. Now you can declare signals and slots and connect them e.g. with signals and slots of your functionality. If someone knows the solution, that fits better to the mitk environment, I would be glad to learn it.
