GreenFire

I am importing from a QJsonDocument and it was working until i gave it a header and it stopped here is the code any suggestions

GreenFire

@void Tem2D::on_Import_clicked()
{

QString inFile;
QFile file;
QString filename = QFileDialog::getOpenFileName(this, "Open file", "" ,"");
file.setFileName(filename);
file.open(QIODevice::ReadWrite | QIODevice::Text);
inFile = file.readAll();
file.close();

QJsonDocument input = QJsonDocument::fromJson(inFile.toUtf8());
sessionModel = input.object();

QString csval = QJsonValue(sessionModel.value("Cs Value")).toString();
ui->csValue_Text->setText(csval);

QString voltageVal = QJsonValue(sessionModel.value("Voltage")).toString();
ui->voltage_Text->setText(voltageVal);

QString efssVal = QJsonValue(sessionModel.value("Energy Filter Slit Size")).toString();
ui->energyFilterSlitSize_Text->setText(efssVal);

QString camVal = QJsonValue(sessionModel.value("Camera")).toString();
ui->camera->setCurrentText(camVal);

QString acqSofVal = QJsonValue(sessionModel.value("Acquisition Software")).toString();
ui->acquistionSoftware->setCurrentText(acqSofVal);

the file i am trying to import looks like this

@{
"TEM 2D": {
"Acquisition Software": "Xplore 3D",
"Camera": "AMT",
"Cs Value": "30",
"Energy Filter Slit Size": "30",
"Voltage": "30"
}
}@

Hi,

Are you sure that QJsonDocument::fromJson is successful ? Did you try to see what the error parameter returns ?

GreenFire

so if the Acquisition software and all the others are at the level of TEM 2D it will import but after i added the TEM 2D it will not and i am stumpped

What about:

@QJsonObject tem2d = input["TEM 2D"].toObject()@

And parse this one ?

This Code is what works
@ QString inFile;
QFile file;
QString filename = QFileDialog::getOpenFileName(this, "Open file", "" ,"");
file.setFileName(filename);
file.open(QIODevice::ReadWrite | QIODevice::Text);
inFile = file.readAll();
file.close();

QJsonDocument input = QJsonDocument::fromJson(inFile.toUtf8());
sessionModel = input.object();

QJsonObject tem2D = QJsonValue(sessionModel.value("TEM 2D")).toObject();

QString csval = QJsonValue(tem2D.value("Cs Value")).toString();
ui->csValue_Text->setText(csval);

QString voltageVal = QJsonValue(tem2D.value("Voltage")).toString();
ui->voltage_Text->setText(voltageVal);

QString efssVal = QJsonValue(tem2D.value("Energy Filter Slit Size")).toString();
ui->energyFilterSlitSize_Text->setText(efssVal);

QString camVal = QJsonValue(tem2D.value("Camera")).toString();
ui->camera->setCurrentText(camVal);

QString acqSofVal = QJsonValue(tem2D.value("Acquisition Software")).toString();
ui->acquistionSoftware->setCurrentText(acqSofVal);@
