The binding you need.
FXBinding allow you to create advanced JavaFX binding on complex model.
Let me show an example :
private StringBinding nameBinding = new FXStringBinding() {
@Override
protected void configure() {
try {
addObservable(aProperty);
addObservable(aProperty.get().bProperty());
addObservable(aProperty.get().bProperty().get().cProperty());
addObservable(aProperty.get().bProperty().get().cProperty().get().stringProperty());
} catch (NullPointerException ignored) {
}
}
@Override
protected String compute() {
try {
return aProperty.get().bProperty().get().cProperty().get().stringProperty().get();
} catch (NullPointerException e) {
return null;
}
}
};Every time the model is changing, we will reconfigure the binding to always get the value you want.
