然后在WndProc回调函数,响应WM_RBUTTONUP函数时创建

1 case WM_RBUTTONUP: 2POINT pt; 3::GetCursorPos(&pt); 4CContextPopMenu* pPopMenu = new CContextPopMenu; 5pPopMenu->PopMenu(hwnd,pt); 6 break;

对每个菜单项的响应在WM_COMMAND消息里处理

文章图片

1 case WM_COMMAND: 2switch(LOWORD(wParam)) 3{ 4case ITEM_MENU_REPLY: 5MessageBox(NULL,TEXT("响应回复菜单项"),TEXT("提示"),MB_OK); 6break; ; 7case ITEM_SUBMENU_UNSEEN: 8MessageBox(NULL,TEXT("响应标记子菜单项"),TEXT("提示"),MB_OK); 9break; 10}
