TextField {
    id: ipField

    width: 180; height: parent.height
    Font{
        bold: true
        pixelSize: 15
    }


    text: settings.ip
    placeholderText: qsTr("255.255.255.255")
    validator: RegExpValidator {
        regExp: /^((?:[0-1]?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])\.){0,3}(?:[0-1]?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])$/
    }

    onEditingFinished: {
        if(text == "") console.log("It will never print ")
        else  console.log(text);
    }
}

I need do action in onEditingFinished handler when field is empty - i can't do that becouse regex accept only ip, so editingFinished() never be emitted

@qtprogrammer123

/^((?:[0-1]?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])?.){0,3}(?:[0-1]?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])?$/

but this would also accept "255...255" for example (empty groups inbetween)

@qtprogrammer123 said in RegExpValidator, empty field:

ut also wonna accept empty field

what is an empty field for you? "255.255", "255...", "255.255.-.-", etc.
