MFC中显示cocos2dx

存在的问题:没实现立即动态更改分辨率,而是通过缩放改变窗口的大小:
void CAnimateMakerView::OnSize(UINT nType, int cx, int cy)
{
CFormView::OnSize(nType, cx, cy);
#if 1
if (::IsWindow(m_picture.m_hWnd))//&&m_bInitCoco)
{
CRect rect;
m_picture.GetWindowRect(rect);
ScreenToClient(rect);
rect.right = cx - rect.left;
rect.bottom = cy - rect.left;
m_picture.MoveWindow(rect);
if (m_bInitCoco)
{
m_picture.resize(rect.Width(),rect.Height());
printf("cocos2d size=%dX%d",rect.Width(),rect.Height());
//CCDirector::sharedDirector()->reshapeProjection(CCSizeMake(rect.Width(),rect.Height()));
}
}
#endif
}
