bind integer to fillproperty
0
I want to bind an integerProperty to the fillProperty of a shape so the change of the integer will change the color of the shape.
Rectangle rect = new Rectangle(20,20);
IntegerProperty intProp = new SimpleIntegerProperty(0);
rect.fillProperty().bind(
Bindings.createObjectBinding(
() -> Color.rgb(intProp.get(), intProp.get(), intProp.get()),intProp));
But I get an error :
A bound value cannot be set
How could I do?

Cannot reproduce with this code alone. Do you try to setrect.fillsomewhere? Analyze the stacktrace to identify the statement setting the value and find out, where the binding is created for the property involved. BTW: The binding you create is the other way around: you bindfillto a binding created based on theIntegerPropertynot the other way round.

tks! I had a rect.setFill(Color.BLACK) somewhere in my code. Removing it solve my problem!
