Problem with SpinBox and double values in QML

[Babs]

Hello,
I'm working on a QML project. I have a problem with double values in my QML. I expose a C++ variable to my QML.

                                            SpinBox{
                                                id:spinPal
                                                minimumValue:  0
                                                maximumValue: 10000

                                                decimals: 2
                                                onValueChanged:  {
                                                    plan.addValue(spinPal.value,index)
                                                    console.log("value added")
                                                }
                                            }

I set the value to 9.18 however it takes the value 9.
Can anyone help?

@Babs SpinBox is for integers, not floating point numbers. But you can use floating point numbers as shown in the documentation: https://doc.qt.io/qt-5/qml-qtquick-controls2-spinbox.html

In the same manner, SpinBox can be customized to accept floating point numbers:

SpinBox {
    id: spinbox
    from: 0
    value: 110
    to: 100 * 100
    stepSize: 100
    anchors.centerIn: parent

    property int decimals: 2
    property real realValue: value / 100

    validator: DoubleValidator {
        bottom: Math.min(spinbox.from, spinbox.to)
        top:  Math.max(spinbox.from, spinbox.to)
    }

    textFromValue: function(value, locale) {
        return Number(value / 100).toLocaleString(locale, 'f', spinbox.decimals)
    }

    valueFromText: function(text, locale) {
        return Number.fromLocaleString(locale, text) * 100
    }
}
