와 이건 대박
뭔가 자바랑 비슷한 삘
// 마우스 클릭 시 좌표 알아오기
void callBackFunc(int event, int x, int y, int flags, void* userdata){
if (event == EVENT_LBUTTONDOWN){
cout << "Left button of the mouse is clicked - position (" << x << ", " << y << ")" << endl;
}
else if (event == EVENT_RBUTTONDOWN){
cout << "Right button of the mouse is clicked - position (" << x << ", " << y << ")" << endl;
}
else if (event == EVENT_MBUTTONDOWN){
cout << "Middle button of the mouse is clicked - position (" << x << ", " << y << ")" << endl;
}
else if (event == EVENT_MOUSEMOVE){
cout << "Mouse move over the window - position (" << x << ", " << y << ")" << endl;
}
}
이렇게 해놓고
main에서
namedWindow(win_name, 1);
setMouseCallback(win_name, callBackFunc, NULL); // 마우스 클릭 이벤트 설정
이렇게만 설정해주면 된다!
