Detailed Description

Parameter compone.

• Write a parameter compone
  • Defined the parameter compone class. eg: CParameterUser
  • Add the parameter compone UI is derived from CParameterUI . eg: CParameterUserUI . and add the follow functions:
    • int SetParameter(CParameter* pParameter);
    • int Accept(bool validity = false);

       
          int SetParameter(CParameter* pParameter);
          int Accept();

• Use a parameter compone
  • Instance the parameter compone class. eg: CParameterNet

        CParameterUser m_User;

    CParameterNet::CParameterNet(CParameterConnecter* parent, const QString &szPrefix)
        : CParameterConnecter(parent, szPrefix)
        , m_nPort(0)
        , m_User(this)
        , m_szPrompt(tr("The host is empty. please set it"))
    {}

  • Call SetParameter and slotAccept
    • CParameterNetUI::SetParameter call CParameterUserUI::SetParameter

      int CParameterNetUI::SetParameter(CParameter *pParameter)
      {
          if(!pParameter) return -1;
          
          m_pNet = qobject_cast<CParameterNet*>(pParameter);
          
          ui->leHost->setText(m_pNet->GetHost());
          ui->spPort->setValue(m_pNet->GetPort());
       
          // Call user UI SetParameter
          ui->wUser->SetParameter(&m_pNet->m_User);
       
          return 0;
      }

    • Check parameter validity: CParameterNetUI::CheckValidity

      bool CParameterNetUI::CheckValidity(bool validity)
      {
          if(validity && ui->leHost->text().isEmpty()) {
              QMessageBox::critical(this, tr("Error"),
                                    m_pNet->GetPrompt());
              qCritical(log) << "The host is empty" << m_pNet->GetPrompt();
              ui->leHost->setFocus();
              return false;
          }
          return true;
      }

    • CParameterNetUI::Accept call CParameterUserUI::Accept

      int CParameterNetUI::Accept()
      {
          int nRet = 0;
       
          m_pNet->SetHost(ui->leHost->text());
          m_pNet->SetPort(ui->spPort->value());
          
          // Accept user UI parameters
          ui->wUser->Accept();
          return nRet;
      }
