title: Not catching all mouse events with wxWidgets
body: <p>Hi  I am am trying to catch mouse movements for a MouseOver function in an app created with Code::Blocks using the wxSmith plugin.  I have stumbled upon a puzzling problem.  EVT_MOUSEWHEEL calling the function in the EventTable works well, but all other macros have no result at all.  And the mousewheel is not <em>really</em> want I want  (I just used it to test...)  This is for Windows.</p>
  
  <p>Here is a the basic problem code (mostly generated by the <strong><em>fantastic</em></strong> wxSmith plugin)  </p>
  
  <p>MouseMain.h</p>
  
  <pre><code>#include &lt;wx/frame.h&gt;
  #include &lt;wx/statusbr.h&gt;
  //*)
  
  class MouseFrame: public wxFrame
  {
      public:
  
          MouseFrame(wxWindow* parent,wxWindowID id = -1);
          virtual ~MouseFrame();
  
      private:
  
          //(*Handlers(MouseFrame)
          void OnQuit(wxCommandEvent&amp; event);
          void OnAbout(wxCommandEvent&amp; event);
          void OnButton1Click(wxCommandEvent&amp; event);
          void MouseOver(wxMouseEvent&amp; event);
          //*)
  
          //(*Identifiers(MouseFrame)
          static const long ID_BUTTON1;
          static const long ID_STATICBITMAP1;
          static const long ID_PANEL1;
          static const long idMenuQuit;
          static const long idMenuAbout;
          static const long ID_STATUSBAR1;
          //*)
  
          //(*Declarations(MouseFrame)
          wxButton* Button1;
          wxStaticBitmap* StaticBitmap1;
          wxPanel* Panel1;
          wxStatusBar* StatusBar1;
          //*)
  
          DECLARE_EVENT_TABLE()
  };
  
  #endif // MOUSEMAIN_H

  <p>...and MouseMain.cpp</p>

      Close();
  }
  
  void MouseFrame::OnAbout(wxCommandEvent&amp; event)
  {
      wxString msg = wxbuildinfo(long_f);
      wxMessageBox(msg, _("Welcome to..."));
  }
  
  void MouseFrame::OnButton1Click(wxCommandEvent&amp; event)
  {
  }
  
  void MouseFrame::MouseOver(wxMouseEvent&amp; event){
      wxMessageBox(_("MouseOver event!"));
  }
  </code></pre>
  
  <p>MouseApp.h</p>
  
  <pre><code>#ifndef MOUSEAPP_H
  #define MOUSEAPP_H
  
  #include &lt;wx/app.h&gt;
  
  class MouseApp : public wxApp
  {
      public:
          virtual bool OnInit();
  };
  
  #endif // MOUSEAPP_H
  </code></pre>
  
  <p>So my big question:
  Why are EVT_MOTION, EVT_RIGHT_DOWN or EVT_RIGHT_DCLICK not calling MouseFrame::MouseOver(wxMouseEvent&amp; event) in the way EVT_MOUSEWHEEL does?</p>
