OpenCV 및 Qt에서 createButton을 사용하도록 연결을 설정하는 방법은 무엇입니까?

opencv highgui 샘플 (예 : connectedcomponents.cpp)을보고 GUI 요소를 추가하는 데 익숙해졌습니다. 현재 내가 버튼을 추가하려고 해요 :OpenCV 및 Qt에서 createButton을 사용하도록 연결을 설정하는 방법은 무엇입니까?

void on_button(int, void*){ 
    cout << "click" << end; 
} 
//in main() 
createButton("test",on_button);

하지만 난 링크 오류 얻을 : 지금까지 내가 제대로 QtCore 라이브러리와 연결하고 있지 않다 이해할 수

합니다. 나는이했습니다 : 행운으로 Qt는 프로젝트의 .PRO 파일에서

mac: LIBS += -F$$PWD/../../../QtSDK/Desktop/Qt/474/gcc/lib/ -framework QtCore
