【已解决】OSG和MFC集成，事件怎么只有一个view可以响应？

lglgaigogo

请无视这个问题，_我不知为什么把tmpView->getCamera()->setAllowEventFocus( false )写了两遍，注释的时候只注释了一个。
如图：


有两个CView，对应到osg里的两个osgViewer::View。如下初始化：

1. void cOSG::SetupCamera(HWND hWnd,short ID)
   
2. {
   
3.         if (NULL == m_CompositeViewer)
   
4.         {
   
5.                 TRACE(_T("Viewer not ready"));
   
6.                 return;
   
7.         }
   
8. 
   
9.         osg::ref_ptr<osgViewer::View> _tmpView;
   
10.         switch(ID)
    
11.         {
    
12.         case MAPVIEW:
    
13.                 m_MapView = new osgViewer::View;
    
14.                 _tmpView = m_MapView;
    
15.                 break;
    
16.         case MAINVIEW:
    
17.         default:
    
18.                 m_MainView = new osgViewer::View;
    
19.                 _tmpView = m_MainView;
    
20.                 break;
    
21.         }
    
22. 
    
23.         m_CompositeViewer->addView(_tmpView.get());
    
24. 
    
25.         // Add a Stats Handler to the viewer
    
26.         //用来显示系统运行的信息，包括帧率，CPU占用等
    
27.         osg::ref_ptr<osgViewer::StatsHandler> stats_handler = new osgViewer::StatsHandler;
    
28.         //按“i”键显示
    
29.         stats_handler->setKeyEventTogglesOnScreenStats('i');
    
30.         _tmpView->addEventHandler(stats_handler.get());
    
31. 
    
32. 
    
33.         // Local Variable to hold window size data
    
34.         RECT rect;
    
35. 
    
36.         // Get the current window size
    
37.         ::GetWindowRect(hWnd, &rect);
    
38. 
    
39.         // Init the GraphicsContext Traits
    
40.         osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits;
    
41. 
    
42.         // Init the Windata Variable that holds the handle for the Window to display OSG in.
    
43.         osg::ref_ptr<osg::Referenced> windata = new osgViewer::GraphicsWindowWin32::WindowData(hWnd);
    
44. 
    
45.         // Setup the traits parameters
    
46.         traits->x = 0;
    
47.         traits->y = 0;
    
48.         traits->width = rect.right - rect.left;
    
49.         traits->height = rect.bottom - rect.top;
    
50.         traits->windowDecoration = false;

53.         traits->setInheritedWindowPixelFormat = true;
    
54.         traits->inheritedWindowData = windata;
    
55. 
    
56.         // Create the Graphics Context
    
57.         osg::ref_ptr<osg::GraphicsContext> gc = osg::GraphicsContext::createGraphicsContext(traits.get());
    
58. 
    
59.         // Assign Graphics Context to the Camera
    
60.         _tmpView->getCamera()->setGraphicsContext(gc.get());
    
61. 
    
62.         // Set the viewport for the Camera
    
63.         _tmpView->getCamera()->setViewport(new osg::Viewport(traits->x, traits->y, traits->width, traits->height));
    
64. 
    
65. 
    
66.         float scale = 17.0;
    
67.         switch(ID)

77.                 _tmpView->getCamera()->setProjectionMatrix( osg::Matrixd::ortho2D(-1.0*scale*traits->width, 1.0*scale*traits->width, -1.0*scale*traits->height, 1.0*scale*traits->height) );
    
78.        
    
79.                 _tmpView->addEventHandler(new testkeyhandler());
    
80.                 _tmpView->setSceneData(m_MapRoot.get());
    
81.                 break;
    
82.         case MAINVIEW:
    
83.         default:
    
84.                 //设置主视图相机
    
85.                 _tmpView->getCamera()->setClearMask(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT);

96. 
    
97.         // Set the Scene Data
    
98. }

这个函数的第一个参数就是MFC里的CView的hWnd。
现在的问题是：显示没有问题，就是第2个View（小地图）不能响应事件。

_tmpView->getCamera()->setAllowEventFocus(false);

对不起，我没有看见啊。。。
我是不是瞎了。唉。谢谢您的提示。

字体不用搞那么大吧
