Question

我有一个复合控件，声明如下：

         class ATL_NO_VTABLE CFooCtrl : 

               public CComObjectRootEx<CComSingleThreadModel>,
               public IDispatchImpl<CFooCtrl, &IID_IFooCtrl, &LIBID_FooLib>,
               public CComCompositeControl<CFooCtrl>,
               public IPersistStreamInitImpl<CFooCtrl>,
               public IOleControlImpl<CFooCtrl>,
               public IOleObjectImpl<CFooCtrl>,
               public IOleInPlaceActiveObjectImpl<CFooCtrl>,
               public IViewObjectExImpl<CFooCtrl>,
               public IOleInPlaceObjectWindowlessImpl<CFooCtrl>,
               public IConnectionPointContainerImpl<CFooCtrl>,
               public IPersistStorageImpl<CFooCtrl>,
               public ISpecifyPropertyPagesImpl<CFooCtrl>,
               public IQuickActivateImpl<CFooCtrl>,
               public IDataObjectImpl<CFooCtrl>,
               public IProvideClassInfo2Impl<&CLSID_FooCtrl, &DIID__IFooCtrlEvents, &LIBID_FooCtrlLib>,
               public IPropertyNotifySinkCP<CFooCtrl>,
               public CComCoClass<CFooCtrl, &CLSID_FooCtrl>,
               public CProxy_IFooCtrlEvents<CFooCtrl>,
            {

        ...

       BEGIN_MSG_MAP(CFooCtrl)
          CHAIN_MSG_MAP(CComCompositeControl< CFooCtrl >)
          DEFAULT_REFLECTION_HANDLER()
          MESSAGE_HANDLER(WM_TIMER, OnTimer)
          MESSAGE_HANDLER(WM_ERASEBKGND, OnEraseBkgnd)
          MESSAGE_HANDLER(WM_KEYDOWN, OnKeyDown)
          MESSAGE_HANDLER(WM_KEYUP, OnKeyUp)
          MESSAGE_HANDLER(WM_LBUTTONDBLCLK, OnLButtonDblClk)
          MESSAGE_HANDLER(WM_LBUTTONDOWN, OnLButtonDown)
          MESSAGE_HANDLER(WM_LBUTTONUP, OnLButtonUP)
          MESSAGE_HANDLER(WM_PAINT, OnPaint)
          MESSAGE_HANDLER(WM_RBUTTONDBLCLK, OnRButtonDblClk)
          MESSAGE_HANDLER(WM_RBUTTONDOWN, OnRButtonDown)
          MESSAGE_HANDLER(WM_RBUTTONUP, OnRButtonUp)
          MESSAGE_HANDLER(WM_MOUSEMOVE, OnMouseMove)
          MESSAGE_HANDLER(WM_MOUSEWHEEL, OnMouseWheel)
          MESSAGE_HANDLER(WM_SIZE, OnSize)
          MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog)
          MESSAGE_HANDLER(WM_DESTROY, OnDestroy)
      END_MSG_MAP()

   LRESULT OnTimer(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnEraseBkgnd(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnKeyDown(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnKeyUp(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnLButtonDblClk(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnLButtonDown(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnLButtonUP(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnPaint(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled); 
   LRESULT OnRButtonDblClk(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnRButtonDown(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnRButtonUp(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnMouseMove(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnMouseWheel(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnSize(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnInitDialog(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
   LRESULT OnDestroy(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);

我得到像OnMouseMove，OnLButtonDown / Up / DblClk这样的事件，但我没有得到像KeyUp，KeyDown或MouseWheel这样的事件。

似乎所有东西都被正确定义了。我搬家了

      CHAIN_MSG_MAP(CComCompositeControl< CFooCtrl >)
      DEFAULT_REFLECTION_HANDLER()

到消息映射的结尾并没有区别。我发现当我删除Reflection_handler（）时，我不会在KeyDown上崩溃，但我怀疑这些是来自我的Python程序，它正在推动控制。

我唯一可以假设的是链接的msg地图正在吃这些事件，但是没有父控制应该对它们感兴趣。

任何人都有任何想法，为什么我得到一些消息而不是其他消息？重新获得这些消息的任何想法？

我相信你的代码使用的是ATL而不是MFC。

复合控件上的键盘处理通过IOleInPlaceActiveObject发生。 ATL中的基本实现将在您的类上调用您的PreTranslateMessage（如果已实现），您可以在它进入TranslateMessage之前获取对该消息的破解。

ATL复合控件是一个控件容器（它是一个可以托管其他activex控件的子对话框）。有关详细信息，请参阅http://www.microsoft.com/msj/1299/containment/containment.aspx

没有在MFC ActiveX复合控件中获取所有Windows消息
