确认交易币的格式

    // Format confirmation message

    QStringList formatted;

    for (const SendCoinsRecipient &rcp :currentTransaction.getRecipients())

    {

        // generate bold amount string

        QString amount = ""+BitcoinUnits::formatHtmlWithUnit(model->getOptionsModel()->getDisplayUnit(),rcp.amount);

        amount.append("");

        // generate monospace address string

        QString address = "" + rcp.address;

       address.append("");

        QString recipientElement;

        if (!rcp.paymentRequest.IsInitialized())// normal payment

        {

            if(rcp.label.length() > 0)             //label with address从标签中选择地址

            {

                recipientElement = tr("%1to %2").arg(amount, GUIUtil::HtmlEscape(rcp.label));

                recipientElement.append(QString("(%1)").arg(address));

            }

            else // just address              //直接输入地址

            {

                recipientElement = tr("%1to %2").arg(amount, address);

            }

        }

        elseif(!rcp.authenticatedMerchant.isEmpty()) // authenticated payment request  如果是已验证的付款请求

        {

            recipientElement = tr("%1 to%2").arg(amount, GUIUtil::HtmlEscape(rcp.authenticatedMerchant));

        }

        else // unauthenticated payment request                //如果是没有验证的付款请求

        {

            recipientElement = tr("%1 to%2").arg(amount, address);

        }

        formatted.append(recipientElement);

    }

其中BitcoinUnits是定义btc单位，显示格式的。比如单位是用BTC还是mBTC，uBTC。数额与单位之间是否有空格等等

      为确认交易做准备

    QString questionString = tr("Are yousure you want to send?");

    questionString.append("

%1");

    if(txFee > 0)

    {

        // append fee string if a fee isrequired  附加上费用信息

        questionString.append("

---

");

       questionString.append(BitcoinUnits::formatHtmlWithUnit(model->getOptionsModel()->getDisplayUnit(),txFee));

       questionString.append(" ");

        questionString.append(tr("added astransaction fee"));

        // append transaction size          附件上交易大小

        questionString.append(" (" +QString::number((double)currentTransaction.getTransactionSize() / 1000) +" kB)");

    }
