Regular Expression for date and time(DD/MM/YYYY hh:mm:ss) in QML

pra7

In QML2 I didn't find any Calender control and I have implemented a control which takes date and time as input and I am using the regular expression for the validation which matches dates including leap year and other validations.

The main problem is space/backspace should also be considered as a valid for example:

\s\s/\s\s/\s\s \s\s:\s\s:\s\s

Following is the code :

TextField{
    id:textEditDate

    width:parent.width * 0.50
    height:parent.height
    text : "01/01/2017 00:00:00"

    inputMask: "99/99/9999 99:99:99"

    validator: RegExpValidator { regExp: /^(((([0\s][1-9\s]|[1\s][0-9\s]|[2\s][0-8\s])[\/]([0\s][1-9\s]|[1\s][012\s]))|((29|30|31)[\/]([0\s][13578\s]|[1\s][02\s]))|((29|30)[\/]([0\s][4,6,9]|11)))[\/]([19\s[2-9\s][0-9\s])\d\d|(^29[\/]02[\/]([19\s]|[2-9\s][0-9\s])(00|04|08|12|16|20|24|28|32|36|40|44|48|52|56|60|64|68|72|76|80|84|88|92|96)))\s([0-1\s]?[0-9\s]|2[0-3\s]):([0-5\s][0-9\s]):([0-5\s][0-9\s])$/}

    horizontalAlignment: Text.AlignHCenter
    inputMethodHints: Qt.ImhDigitsOnly
}

Now, everything works well except for the year and I am not able to match backspace/space for the year and user is not able to clear the year.

Can you please suggest how to achieve this ? or is there any other method to do this.

@pra7 I'm afraid this does not help with your problem, but attempting to deal with validating leap year dates via regular expressions seems extraordinary to me!

For your Calendar control:

?

But I don't imagine there will be a date+time control. I had to implement that myself in previous (non-Qt) projects.

@JNBarchan Thanks for the links. I need calendar control in QML2, not in QML1.

@pra7 See also https://forum.qt.io/topic/82700/datepicker-anyone. BTW you must mean Quick Controls 2, not QML2. You also can use Controls 1 elements in Controls 2 application, although the look&feel may be a problem.
