qt createWindowContainer embed realvnc
实际使用的vnc服务端是realvnc 5，后来实际使用的方案是vncviewer嵌入;

android 下的vncserver

时间旧了，有的代码具体是解决什么问题的我也记不清了;
依稀记得主体上分为两部分，一部分是嵌入的工具程序；
另一部分是用于注入realvnc客户端的dll(为了捕捉客户端很早的窗口句柄创建采用的静态注入);
//=======这步逻辑应该是当时出现嵌入后的vnc客户端无法输入按键文字的问题的解决方案==========

//============为了保存连接设置可以通过-config传入.vnc的连接配置文件名======================
.vnc文件一般结构

//=========嵌入服务端和vnc客户端之间的交互我当时采用的是QSharedMemory
用于获取一些关注的客户端句柄的创建和显示
//==================隐藏嵌入的客户端的任务栏图标========================

}//=========VNC客户端部分，鼠标右键时添加active和setfocus消息以处理嵌入后获取不到焦点消息的问题======================
LRESULT CALLBACK hookMouseProc( int nCode, WPARAM wParam,LPARAM lParam)

...//=========在SetWindowPos函数上挂钩泳衣检测最大化和恢复======================
BOOL WINAPI newSetWindowPos( HWND hWnd, HWND hWndInsertAfter, int X, int Y, int cx, int cy, UINT uFlags)
{
if(aCDesktopWin && hWnd==wndMap[QString("vwr::CDesktopWin")])

int id=GetWindowLong(hWnd,GWLP_ID);
GetWindowText(hWnd,szText1,GetWindowTextLength(hWnd)+1);--这部分又记不清了，挂钩相关的也忘的差不多了可以打拳去了
//=========python嵌入c++相关的我在另一篇博客中说明=========================
