给quick-cocos2d-x增加windows下模拟器右键,步骤如下

1.修改LRESULT CCEGLView::WindowProc(UINT message, WPARAM wParam, LPARAM lParam),增加右键按下和抬起事件,大体参照左键的抬起和按下,具体代码如下所示:

case WM_RBUTTONDOWN:

#if(_MSC_VER >= 1600)

// Don't process message generated by Windows Touch

if (m_bSupportTouch && (s_pfGetMessageExtraInfoFunction() & MOUSEEVENTF_FROMTOUCH) == MOUSEEVENTF_FROMTOUCH) break;

#endif /* #if(_MSC_VER >= 1600) */

if (m_pDelegate && MK_RBUTTON == wParam)

{

POINT point = {(short)LOWORD(lParam), (short)HIWORD(lParam)};

CCPoint pt(point.x, point.y);

pt.x /= m_fFrameZoomFactor;

pt.y /= m_fFrameZoomFactor;

CCPoint tmp = ccp(pt.x, m_obScreenSize.height - pt.y);

if (m_obViewPortRect.equals(CCRectZero) || m_obViewPortRect.containsPoint(tmp))

{

m_bCaptured = true;

SetCapture(m_hWnd);

int id = 0;

handleRTouchesBegin(1, &id, &pt.x, &pt.y);

}

}

break;

2.修改CCEGLViewProtocol,添加右键的handle,代码如下

void CCEGLViewProtocol::handleRTouchesBegin(int num, int ids[], float xs[], float ys[])

{

CCSet set;

for (int i = 0; i < num; ++i)

{

int id = ids[i];

float x = xs[i];

float y = ys[i];

CCInteger* pIndex = (CCInteger*)s_TouchesIntergerDict.objectForKey(id);

int nUnusedIndex = 0;

// it is a new touch

if (pIndex == NULL)

{

nUnusedIndex = getUnUsedIndex();

// The touches is more than MAX_TOUCHES ?

if (nUnusedIndex == -1) {

CCLOG("The touches is more than MAX_TOUCHES, nUnusedIndex = %d", nUnusedIndex);

continue;

}

CCTouch* pTouch = s_pTouches[nUnusedIndex] = new CCTouch();

pTouch->setTouchInfo(nUnusedIndex, (x - m_obViewPortRect.origin.x) / m_fScaleX,

(y - m_obViewPortRect.origin.y) / m_fScaleY);

//CCLOG("x = %f y = %f", pTouch->getLocationInView().x, pTouch->getLocationInView().y);

CCInteger* pInterObj = new CCInteger(nUnusedIndex);

s_TouchesIntergerDict.setObject(pInterObj, id);

set.addObject(pTouch);

pInterObj->release();

}

}

if (set.count() == 0)
