QTableWidget does not show values that come from a QMap

SpaceToon

Hey guys,

I have a QMap QMap<QString, float> sensorData; and I insert values like this:

//these are just placeholders for my actual sensor values - these hardcoded values are just for testing now

    float acc_x = 0.5;
    float acc_y = 1.5;
    float acc_z = 2.5;
    float gyr_x = 3.5;
    float gyr_y =4.5;
    float gyr_z =5.5;

    sensorData =
    {
        {"acc_x", acc_x},
        {"acc_y", acc_y},
        {"acc_z", acc_z},
        {"gyr_x", gyr_x},
        {"gyr_y", gyr_y},
        {"gyr_z", gyr_z},

    };

In my function (which receives the QMap via Signal/Slot), which is trying to print these values to a QWidgetTable I have:

    qDebug() << sensorData["acc_x"];
    ui->dataTable->setItem(0,0, new QTableWidgetItem(sensorData["acc_x"]));
    ui->dataTable->setItem(0,1, new QTableWidgetItem(sensorData["acc_y"]));
    ui->dataTable->setItem(0,2, new QTableWidgetItem(sensorData["acc_z"]));
    ui->dataTable->setItem(1,0, new QTableWidgetItem(sensorData["gyr_x"]));
    ui->dataTable->setItem(1,1, new QTableWidgetItem(sensorData["gyr_y"]));
    ui->dataTable->setItem(1,2, new QTableWidgetItem(sensorData["gyr_z"]));

But the values are not shown in the table, the table is empty. But in the output console the correct value is printed for my
qDebug() << sensorData["acc_x"]; so what might be wrong ?

Hi,

You are triggering this overload since you have a numerical value.

Do an explicit conversion using QString::number.

@SGaist Thank oyu, that worked!
