Detailed Description

the parameters of connecter interface.

It only valid in plugin.

Note

• The interface only is implemented and used by plugin.
• The application cannot access it directly, it can only be set via CConnecter::OpenDialogSettings.
• The plugin can access via CConnecterThread::GetParameter
• Need access the client parameters(CParameterClient), must be derived from the class. Access the client parameters(CParameterClient) via CParameterConnecter::GetParameterClient()
• Use connecter parameter

Use CParameterClient

Set CParameterClient for CParameterConnecter

• If the parameters of connecter(CParameterConnecter or it's derived class) requires a CParameterClient.
  • Please instantiate the parameters of connecter in the constructor of the CConnecter or it's derived class. ag:

        CParameterFreeRDP m_ParameterFreeRdp;

  • Call CConnecter::SetParameter to set the parameters. ag:

    CConnecterFreeRDP::CConnecterFreeRDP(CPluginClient *plugin)
        : CConnecterThread(plugin)
    {
        qDebug(log) << Q_FUNC_INFO;
        //WLog_SetLogLevel(WLog_GetRoot(), WLOG_TRACE);
     
        // 在 freerdp_client_context_free 中释放
        //m_ParameterFreeRdp.m_pSettings = freerdp_settings_new(0);
    }

  • Default set the CParameterClient for the parameters of connecter. See: CClient::CreateConnecter .

    CConnecter* CClient::CreateConnecter(const QString& id)
    {
        auto it = m_Plugins.find(id);
        if(m_Plugins.end() != it)
        {
            bool bRet = 0;
            qDebug(log) << "CreateConnecter id:" << id;
            auto plugin = it.value();
            CConnecter* p = nullptr;
            if(plugin) {
                //p = plugin->CreateConnecter(id);
                bRet = QMetaObject::invokeMethod(
                    plugin,
                    "CreateConnecter",
                    Qt::DirectConnection,
                    Q_RETURN_ARG(CConnecter*, p),
                    Q_ARG(QString, id));
                if(!bRet) {
                    qCritical(log) << "Create CConnecter fail.";
                    return nullptr;
                }
            }
            if(p) {
                int val = 0;
                //p->Initial();
                bRet = QMetaObject::invokeMethod(
                    p,
                    "Initial",
                    Qt::DirectConnection,
                    Q_RETURN_ARG(int, val));
                if(!bRet || val) {
                    qCritical(log) << "Connecter initial fail" << bRet << val;
                    DeleteConnecter(p);
                    return nullptr;
                }
                //p->SetParameterClient(m_ParameterClient)
                bRet = QMetaObject::invokeMethod(
                    p,
                    "SetParameterClient",
                    Qt::DirectConnection,
                    Q_RETURN_ARG(int, val),
                    Q_ARG(CParameterClient*, m_pParameterClient));
                if(!bRet || val) {
                    qCritical(log) << "SetParameterClient fail" << bRet << val;
                    DeleteConnecter(p);
                    return nullptr;
                }
            }
            return p;
        }
        return nullptr;
    }

  • If you are sure to the parameter does not need CParameterClient. please overload the CConnecter::SetParameterClient in the CConnecter derived class, don't set it.

Use CParameterClient in CParameterConnecter

• Use CParameterConnecter::GetParameterClient() get CParameterClient in the parameters of connecter(CParameterConnecter or it's derived class)
• The parameters of connecter(CParameterConnecter or it's derived class) use the value of CParameterClient as its initial value.
  Please override CParameterConnecter::slotSetParameterClient and initialize the relevant values in it.
  For example, Whether to save the password with the member value of CParameterClient as its initialization value.

  void CParameterUser::slotSetParameterClient()
  {
      if(!GetParameterClient()) {
          QString szErr = "The CParameterClient is null";
          qCritical(log) << szErr;
          Q_ASSERT_X(false, "CParameterUser", szErr.toStdString().c_str());
          return;
      }
   
      if(GetParameterClient())
      {
          if(GetParameterClient()->GetEnableSystemUserToUser())
              SetUser(RabbitCommon::CTools::GetCurrentUser());
          SetSavePassword(GetParameterClient()->GetSavePassword());
          SetSavePassphrase(GetParameterClient()->GetSavePassword());
      }
   
      return;
  }

CParameterConnecter category

Because there may be many parameters, it is necessary to classify them by parameter category. Each category can derive a separate class from this class. Each category is then used as a member variable in the derived classes of this class.

For example:
Connection parameters include the following categories:

• Base

  class CParameterBase : public CParameterConnecter

• User

  class CParameterUser : public CParameterConnecter

• Video

  class CParameterVideo : public CParameter

• Audio

  class CParameterAudio : public CParameter

CParameterBase, CParameterUser need CFrmParameterClient, so that it must derived from CParameterConnecter. other is derived from CParameter.

Then the connection parameters can be a combination of the above categories:

class CParameterConnect : public CParameterBase
{
public:
    explicit CParameterConnect(CParameterConnecter *parent = nullptr);
 
    CParameterUser m_User;
    CParameterVideo m_Video;
    CParameterAudio m_Audio;
};
 
CParameterConnect::CParameterConnect(CParameterConnecter *parent = nullptr)
 : CParameterBase(parent),
   m_User(this, "Host"),
   m_Video(this),
   m_Audio(this)
{}

Note

• The connect parameter must be derived from CParameterBase
• When a member is instantiated, the constructor must set the parent to the instance of CParameterConnecter(this).
• Set CParameterClient for CParameterConnecter
