Link two object attributes to each other

Grek

I'm new to QT and have a question about linking two attributes to eachother.
I want to be able to alter one which should change the other.

example:

        TextField{
            id:textBox
            text:slideBox.x
            validator: IntValidator{
                top: 255
                bottom: 0
                }
            maximumLength: 3
        }

        Rectangle{
            id:slideBox
            width: 10
            height: 15
            anchors.fill: parent
            border.width: 1
            x : textBox.text

            MouseArea {
                anchors.fill: parent
                drag.target: parent
                drag.threshold: 0
                drag.maximumX: 400
                drag.minimumX: 30
            }
        }

Here "slideBox.x" is changed by the text field and "TextField.text" is changed by dragging the box. I know that this creates a nasty loop but I hope you get the idea of what I want to do. Is this possible to do in a good way?

TextField{
            id:textBox
            text: slideBox.x
            validator: IntValidator{
                top: 255
                bottom: 0
                }
            maximumLength: 3

            // onEditingFinished or onTextChanged or onAccepted( choose which fits better )
            onEditingFinished: slidebox.x = parseInt(text)
        }

        Rectangle{
            id:slideBox
            width: 10
            height: 15
            anchors.fill: parent
            border.width: 1
            //x : textBox.text  

            MouseArea {
                anchors.fill: parent
                drag.target: parent
                drag.threshold: 0
                drag.maximumX: 400
                drag.minimumX: 30
            }
        }
