Using Date.fromLocalTimeString in property binding

[Panke]

I've got a Q_GADGET called Incident with a QDateTime property dateTime. I want to edit this property using an QtQiuck TextField, thus I've got something like this:

Item {
property variant incident
   TextField {
            id: time
            placeholderText: "Time"
            text: .incident.dateTime.toLocaleTimeString().slice(0,5)
            validator: RegExpValidator { regExp: /\d\d:\d\d/ }
        }
 Binding {
        target: incident.dateTime
        when: time.acceptableInput
        value: {
            var d = incident.dateTime;
            var t = Date.fromLocalTimeString(Qt.locale(), time.text, "hh:mm");
            d.setMinutes(t.getMinutes());
            d.setHours(t.getHours());
            return d
        }
}

What I am trying to do is to read keep the value in the incident-property and the text field in sync, also I only want to change the hour and the minutes of the dateTime object. However when I try to call the fromLocalTimeString method, I get the following error message:

TypeError: Property 'fromLocalTimeString' of object function() { [code] } is not a function

How do I call this function correctly and is the basic approach correct?

@Panke said in Using Date.fromLocalTimeString in property binding:

See the QML Date docs:

The QML Date object extends the JS Date object with locale aware functions.

This leads to:

Binding {
        target: incident.dateTime
        when: time.acceptableInput
        value: {
            var d = incident.dateTime;
            // <<<<<<<<<<<<<<<<<<<<<<<<
            var date = new Date();
            var t = date.fromLocalTimeString(Qt.locale(), time.text, "hh:mm");
            // >>>>>>>>>>>>>>>>>>>>
            d.setMinutes(t.getMinutes());
            d.setHours(t.getHours());
            return d
        }
}

@raven-worx Thanks.

From the linked documentation page:

import QtQml 2.0

QtObject {
    property var locale: Qt.locale()
    property string dateTimeString: "Tue 2013-09-17 10:56:06"

    Component.onCompleted: {
        print(Date.fromLocaleString(locale, dateTimeString, "ddd yyyy-MM-dd hh:mm:ss"));
    }
}

Is the documentation wrong or is there something I don't get?

@Panke
it's not impossible that the docs are wrong and IMHO they are in this case.
At least all the other lines in the docs refering to toLocaleTimeString() are all constructing a new Data instance.

But honestly i have no clue why the return types of those methods are string?
When the text says that it converts to a Date object.

@Panke
But i also noticed a typo in your code:
You wrote fromLocalTimeString instead of fromLocaleTimeString (note the e at the end of Locale)
If thats the issue the docs are correct afterall ;)

[Panke]

You wrote fromLocalTimeString instead of fromLocaleTimeString (note the e at the end of Locale)

That actually solves the issue. Thank you. Didn't look close enough thinking that on object function() { [code] } couldn't have such a property anyway.
