QT 读写.ini配置文件

当需要存放的数据量较少时合适使用.ini配置文件。

#include <QCoreApplication>
#include <QSettings>

void SystemSetWindow::readLoginConfig()
{
    QString fileName;
    fileName = QCoreApplication::applicationDirPath();
    fileName += "/loginConfig.ini";

    QSettings settings(fileName, QSettings::IniFormat);
    settings.setIniCodec("UTF8");

    m_bCheckBoxLoginStatus = settings.value("AutoLogin").toBool();
    m_sCityId = settings.value("City").toString();
}
void SystemSetWindow::writeLoginConfig()
{
    QString fileName;
    fileName = QCoreApplication::applicationDirPath();
    fileName += "/loginConfig.ini";

    QSettings settings(fileName, QSettings::IniFormat);
    settings.setIniCodec("UTF8");
    settings.setValue("AutoLogin", QVariant(m_pAlarmServerIP->text()));
    settings.setValue("City", QVariant(m_pAlarmPort->text()));
}

会产生一个loginConfig.ini的配置文件
