    鼠标事件

    就像前几节介绍的那样，Cocos2d-x 支持响应鼠标事件

    创建鼠标事件监听器：

    1. _mouseListener = EventListenerMouse::create();
    2. _mouseListener->onMouseMove = CC_CALLBACK_1(MouseTest::onMouseMove, this);
    3. _mouseListener->onMouseUp = CC_CALLBACK_1(MouseTest::onMouseUp, this);
    4. _mouseListener->onMouseDown = CC_CALLBACK_1(MouseTest::onMouseDown, this);
    5. _mouseListener->onMouseScroll = CC_CALLBACK_1(MouseTest::onMouseScroll, this);
    7. _eventDispatcher->addEventListenerWithSceneGraphPriority(_mouseListener, this);
    9. void MouseTest::onMouseDown(Event *event)
    10. {
    11.     // to illustrate the event....
    12.     EventMouse* e = (EventMouse*)event;
    13.     string str = "Mouse Down detected, Key: ";
    14.     str += tostr(e->getMouseButton());
    15. }
    17. void MouseTest::onMouseUp(Event *event)
    18. {
    19.     // to illustrate the event....
    20.     EventMouse* e = (EventMouse*)event;
    21.     string str = "Mouse Up detected, Key: ";
    22.     str += tostr(e->getMouseButton());
    23. }
    25. void MouseTest::onMouseMove(Event *event)
    26. {
    27.     // to illustrate the event....
    28.     EventMouse* e = (EventMouse*)event;
    29.     string str = "MousePosition X:";
    30.     str = str + tostr(e->getCursorX()) + " Y:" + tostr(e->getCursorY());
    31. }
    33. void MouseTest::onMouseScroll(Event *event)
    34. {
    35.     // to illustrate the event....
    36.     EventMouse* e = (EventMouse*)event;
    37.     string str = "Mouse Scroll detected, X: ";
    38.     str = str + tostr(e->getScrollX()) + " Y: " + tostr(e->getScrollY());
    39. }
