Detailed Description

Operational parameter interface.

Valid only within the plugin.

Note

• The interface only is implemented and used by plugin.
• The application cannot access it directly, it can only be set via COperate::OpenDialogSettings.
• The plugin can access via COperateDesktop::GetParameter(), COperateTerminal::GetParameter() etc
• Need access the global parameters (CParameterPlugin), must be derived from the class. Access the global parameters (CParameterPlugin) via CParameterOperate::GetGlobalParameters()
• Use connecter parameter

Set and get global parameters. Parameters that need to manipulate global parameters should be derived from this class.

Use CParameterPlugin

Set CParameterPlugin for CParameterOperate

• If the parameters of operate(CParameterOperate or it's derived class) requires a CParameterPlugin.
  • Please instantiate the parameters of operate in the constructor of the COperate or it's derived class. ag:

        CParameterFreeRDP m_ParameterFreeRdp;

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

    int COperateFreeRDP::Initial()
    {
        qDebug(log) << Q_FUNC_INFO;
        int nRet = 0;
        nRet = COperateDesktop::Initial();
        if(nRet) return nRet;
        nRet = SetParameter(&m_ParameterFreeRdp);
        return nRet;
    }

  • Default set the CParameterPlugin for the parameters of operate. See: CPlugin::CreateOperate .

    COperate* CPlugin::CreateOperate(
        const QString &szId, CParameterPlugin* para)
    {
        COperate* p = OnCreateOperate(szId);
        if(p) {
            int nRet = 0;
            //nRet = p->Initial();
            bool bRet = QMetaObject::invokeMethod(
                p,
                "Initial",
                Qt::DirectConnection,
                Q_RETURN_ARG(int, nRet));
            if(!bRet) {
                qCritical(log) << "Call p->Initial() fail.";
                return nullptr;
            }
            if(nRet) {
                qCritical(log) << "Operate initial fail" << nRet;
                DeleteOperate(p);
                return nullptr;
            }
            //nRet = p->SetGlobalParameters(para);
            bRet = QMetaObject::invokeMethod(
                p,
                "SetGlobalParameters",
                Qt::DirectConnection,
                Q_RETURN_ARG(int, nRet),
                Q_ARG(CParameterPlugin*, para));
            if(!bRet) {
                qCritical(log) << "Call p->SetParameterClient(para) fail.";
                return nullptr;
            }
            if(nRet) {
                qCritical(log) << "SetParameterClient fail" << nRet;
                DeleteOperate(p);
                return nullptr;
            }
        }
        return p;
    }

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

Use CParameterPlugin in CParameterOperate

• Use CParameterOperate::GetGlobalParameters() get CParameterPlugin in the parameters of operate(CParameterOperate or it's derived class)
• The parameters of operate(CParameterOperate or it's derived class) use the value of CParameterPlugin as its initial value.
  Please override CParameterOperate::slotSetGlobalParameters and initialize the relevant values in it.
  For example, Whether to save the password with the member value of CParameterPlugin as its initialization value.

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

CParameterOperate 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:
Operate parameters include the following categories:

• Base

  class CParameterBase : public CParameterOperate

• User

  class CParameterUser : public CParameterOperate

• Video

  class CParameterVideo : public CParameter

• Audio

  class CParameterAudio : public CParameter

CParameterBase, CParameterUser need global parameters, so that it must derived from CParameterOperate. other is derived from CParameter.

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

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

Note

• The connect parameter must be derived from CParameterOperate
• The operate parameters that require global parameters must be derived from CParameterOperate, otherwise they can be derived from CParameter
• When a member is instantiated, the constructor must set the parent to the instance of CParameterOperate(this).
• Set CParameterPlugin for CParameterOperate
