대충 이렇게 쓰면 되려나?
void CallBackFunc_Mouse(int event, int x, int y, int flags, void* userdata) { switch(event) { case EVENT_MOUSEMOVE: //x,y break; case EVENT_LBUTTONDOWN: case EVENT_LBUTTONUP:
case EVENT_RBUTTONDOWN: case EVENT_RBUTTONUP:
case EVENT_MBUTTONDOWN: case EVENT_MBUTTONUP:
case EVENT_LBUTTONDBLCLK: case EVENT_RBUTTONDBLCLK: case EVENT_MBUTTONDBLCLK: // case EVENT_MOUSEWHEEL: // case EVENT_MOUSEHWHEEL: } } setMouseCallback("My Window", CallBackFunc_Mouse, NULL); |
2.4.1 에서는 마우스 휠 이벤트가 없다. 3.0.0 부터 지원하는 듯
