    implicitWidth: 200
    implicitHeight: 30

Answer 1

To answer your question, here's the working solution below.

 TextField {
    id: textField1
    implicitWidth: 200
    implicitHeight: 30
    validator: RegExpValidator{regExp: /^[0-9,/]+$/}
}

Button{
    onClicked:{console.log(textField1.text)}
}

To prevent a user from entering something use a text validator in Qt Found here. It makes use of RegEx so u have more control.

by doing this you completely prevent a user from being able to enter the characters you dont want.

Answer 2

on android and ios devices use

inputMethodHints : Qt.ImhFormattedNumbersOnly

in TextField to Open Keyboard on Only number input That is includes decimal point and minus sign. and Other inputMethodHints TextFiled QML

and use Regex in Validator for add Restrictions on Input.

Example:

TextField{
    validator: RegExpValidator{regExp: /[0-9,/]*/}
}
