Display numeric keyboard in Windows Surface

[Celine_123]

Hello,
I work with a Windows Surface Pro 4 tablet and I want to display the numeric keyboard automatically when the user clicks on a TextField.

I tried :

TextField {
    inputMethodHints: Qt.ImhFormattedNumbersOnly
}

But It does nothing. I also tried other inputMethodHints values but that doesn't work either.

Any ideas ? Will I have to code my own keyboard?

Thanks.
