QSettings and xml

andreyc

Why do you declare writeXmlFile and readXmlFile again in the lines 8 and 9 in file.cpp above?

andreyc

According to "QSettings::registerFormat":http://qt-project.org/doc/qt-5/qsettings.html#registerFormat documentation the writeFunc and readFunc must be either standalone function or static member functions.
In the "example that you used":http://www.openshots.de/2011/03/qsettings-mit-xml-format/ both functions are standalone functions.

Move both functions out of the class or make them the static functions of the class.

@zabdielfer as @andreyc sayed. You have to change the methods readXmlFile and writeXmlFile to static members..

Especially:
in your header file:
change

bool readXmlFile(QIODevice &device, QSettings::SettingsMap &map);
bool writeXmlFile(QIODevice &device, const QSettings::SettingsMap &map);

to
static bool readXmlFile(QIODevice &device, QSettings::SettingsMap &map);
static bool writeXmlFile(QIODevice &device, const QSettings::SettingsMap &map);

and remove in the implementation file (QControlPanel constructor) the forward declarations

bool readXmlFile(QIODevice &device, QSettings::SettingsMap &map);
bool writeXmlFile(QIODevice &device, const QSettings::SettingsMap &map);

Hi:
how could I get all attributes of a node for example this xml file
<Ajustes>
<Personalizado>
<AjustesECG setting_ecg.V_on="false" setting_ecg.marcapasos="false" setting_ecg.alarm_on_st2="true" />
<AjustesRSP setting_rsp.gain="2" setting_rsp.apnea_delay="1" setting_rsp.alarm_on="true" />
<AjustesNIBP setting_pni.period="2" setting_pni.alarm_sy_on="true" setting_pni.alarm_di_on="true"
<AjustesCO2 setting_cos.apnea_delay="1" setting_cos.compensation="false" setting_cos.alarm_cex_on="true" />
<AjustesNO2 setting_nos.alarm_nex_on="false" setting_nos.alarm_nin_on="false" setting_nos.alarm_nex_lvl="1"
<AjustesTNM setting_nmt.current="0" setting_nmt.period="0" setting_nmt.type="0" setting_nmt.width="0" />
</Personalizado>
<Fabrica>
<AjustesECG setting_ecg.V_on="false" setting_ecg.marcapasos="false" setting_ecg.alarm_on_st2="true" />
<AjustesRSP setting_rsp.gain="2" setting_rsp.apnea_delay="1" setting_rsp.alarm_on="true" />
<AjustesNIBP setting_pni.period="2" setting_pni.alarm_sy_on="true" setting_pni.alarm_di_on="true"
<AjustesCO2 setting_cos.apnea_delay="1" setting_cos.compensation="false" setting_cos.alarm_cex_on="true" />
<AjustesNO2 setting_nos.alarm_nex_on="false" setting_nos.alarm_nin_on="false" setting_nos.alarm_nex_lvl="1"
<AjustesTNM setting_nmt.current="0" setting_nmt.period="0" setting_nmt.type="0" setting_nmt.width="0" />

QXmlStreamReader * rdr = new QXmlStreamReader("path");

while (!rdr->atEnd()) {

    QXmlStreamReader::TokenType token = rdr->readNext();

    if(token == QXmlStreamReader::StartDocument)
        continue;

    if (rdr->name() == "Personalizado") {
        continue;
    }


    if(rdr->name() == "AjustesECG"){
        qDebug() << rdr->attributes().value("setting_ecg.V_on").toString();
