WP基于消息响应

WPF不是基于消息响应的，WPF用的路由事件，如果想响应消息参考以下代码

C# code

    
    
    
    

     
     
     
      
     
     
     
     private
     
     
     
      
     
     
     
     const
     
     
     
      
     
     
     
     int
     
     
     
      WM_MOUSEMOVE 
     
     
     
     =
     
     
     
      
     
     
     
     0x200
     
     
     
     ; IntPtr WndProc(IntPtr hwnd, 
     
     
     
     int
     
     
     
      msg, IntPtr wParam, IntPtr lParam, 
     
     
     
     ref
     
     
     
      
     
     
     
     bool
     
     
     
      handled) { 
     
     
     
     if
     
     
     
      (msg 
     
     
     
     ==
     
     
     
      WM_MOUSEMOVE) { 
     
     
     
     //
     
     
     
     在这里添加鼠标移动的响应
     
     
     
      
     
     
     
      handled 
     
     
     
     =
     
     
     
      
     
     
     
     true
     
     
     
     ; } 
     
     
     
     return
     
     
     
      (
     
     
     
     new
     
     
     
      IntPtr(
     
     
     
     0
     
     
     
     )); } 
     
     
     
     //
     
     
     
     窗口Loaded事件响应
     
     
     
      
     
     
     
     private
     
     
     
      
     
     
     
     void
     
     
     
      Window_Loaded(
     
     
     
     object
     
     
     
      sender, RoutedEventArgs e) { IntPtr hwnd 
     
     
     
     =
     
     
     
      
     
     
     
     new
     
     
     
      WindowInteropHelper(
     
     
     
     this
     
     
     
     ).Handle; HwndSource hs 
     
     
     
     =
     
     
     
      HwndSource.FromHwnd(hwnd); hs.AddHook(
     
     
     
     new
     
     
     
      HwndSourceHook(WndProc)); }
