5按照官方说明，要讲Hge使用到子窗口中，需要做以下6个步骤：a.设置窗口 hge->System_SetState(HGE_HWNDPARENT, hwnd);b. 设置鼠标 hge->System_SetState(HGE_HIDEMOUSE, false);c. 重新定义windows消息循环for(;;){ if(hge->System_GetState(HGE_HWND)) hge->System_Start(); if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) { if(msg.message == WM_QUIT) break; DispatchMessage(&msg); }}d.如果窗口大小变化，需要调用MoveWindow(hge->System_GetState(HGE_HWND), x, y, width, height, true);e. 添加窗口关闭处理代码 case WM_DESTROY: FreeLoadedHGEResources(); hge->System_Shutdown(); PostQuitMessage(0); return FALSE;f. 如果Hge子窗口需要相应键盘和鼠标消息，请设置窗口焦点。SetFocus(hge->System_GetState(HGE_HWND));
