Binding ColorPicker in JavaFX to Label Background property

Question

Works well for foreground by simply:

    ObjectProperty op = label.textFillProperty();
    ColorPicker cp = new ColorPicker(Color.GRAY);   
    ...             
    op.bind(cp.valueProperty());

How do I do it for Background - not even sure it is possible, due to the complexity of Background property

Answer 1

First, don't use raw types. The code you posted should be

ObjectProperty<Paint> op = label.textFillProperty();
ColorPicker cp = new ColorPicker(Color.GRAY);   
...             
op.bind(cp.valueProperty());

For the background you can use Bindings.createObjectBinding():

ObjectProperty<Background> background = label.backgroundProperty();
background.bind(Bindings.createObjectBinding(() -> {
    BackgroundFill fill = new BackgroundFill(cp.getValue(), CornerRadii.EMPTY, Insets.EMPTY);
    return new Background(fill);
}, cp.valueProperty());
