Hi Jim,

This is my solution :-)
[code]

var slider : SwingSlider;

Stage {
title: "Application title"
width: 400
height: 400
scene: Scene {

content: [
slider = SwingSlider {
minimum: 0
maximum: 360
value: 0
vertical: false
foreground: Color.WHITE
}

Text {
font: Font.font("Courier", FontWeight.BOLD, 24)

fill: Color.BLUE
x: 130,
y: 200
content: bind "Angle: {slider.value}"
rotate: bind slider.value
}
]
}

}

[/code]

Hi mr. James:

This is my solution; maybe it's too late, but it's a good exercise.

Thanks a lot
