How to make inputMask with QML

[jago]

Hi, what I need is an inputMask of this format: 0000.00. When I click the buttons (0-9), the TextInput should change accordingly. I tried it like this, but it didn't function:

TextInput {
id: displayNumbers6Text
inputMask: "0000.00"
color: "#ffffff"
}

Buttons have MouseArea, for example for Number 2:

MouseArea {
anchors.fill: parent
onPressed: {parent.buttonColor = "#a0c119"}
onReleased: {parent.buttonColor = "#000000"}
onClicked: {
displayNumbers6Text.inputMask = displayNumbers6Text.inputMask + "2"
}
cursorShape: Qt.PointingHandCursor
}

Please help!
