Focus problems making a custom spinner

[uroller]

I'm sorry if my terminology is wrong or I'm way off, I'm quite new to QML.

I'm looking to make a little GUI with QML to change some database entries. One type of value needs a simple spinner that increments the value with the arrow keys.

The menu is passed a label and an item to get the value from the database:

@
import QtQuick 1.0

Rectangle
{
property alias label: label.text;
property Item value;

height: 50;
width: parent.width;

Text {
    id: label;
    // ... other properties
}

Text {
    id: value_text;
    text: value.get_value();
    // ... other properties
}

Keys.onPressed:
{
    if (event.key == Qt.Key_Enter) {
        event.accepted = true;
        value.focus=true;
    }
}

}
@

Getting the value works fine, but I can't figure out how to give the value Item focus. I figured setting value.focus = true would be enough but I never get into the onPressed() handler of my item:

@
import QtQuick 1.0

Item
{
property string property_name;

function get_value() ...

Keys.onPressed:
{
    if (event.key == Qt.Key_Right) { // decrement value }

    if (event.key == Qt.Key_Left) { // increment value }
}

}
