单击图片产生窗口

做了一个小效果,单击osg中的图片产生一个dialog窗口

首先是MFC自定义消息 http://www.360doc.com/content/12/0810/10/6973384_229360436.shtml

将消息加在了MFCView.h和.cpp中，

自己写了一个类从OSG向MFC传消息

.h

#define WM_USERMESSAGE WM_USER+100

class Send
{
public:
 Send(HWND hWnd):m_hWnd(hWnd)
 {
 }
 void sendM(std::string name);
 ~Send(){};
private:
 HWND m_hWnd;
};

.cpp

void Send::sendM(std::string name)
{
 std::string tmp=name;
 SendMessage(m_hWnd,WM_USERMESSAGE,(WPARAM)0,(LPARAM)&tmp);
 //PostMessage(m_hWnd,WM_USERMESSAGE,(WPARAM)0,(LPARAM)&tmp);

}

OSG初始化时加m_send = new Send(m_hWnd);

ButtonHandler中构造函数改为ButtonHandler(osgViewer::Viewer *viewer,Send* p_send):mViewer(viewer),lastSelect(0),m_send(p_send){}
