How to add multiple BooleanBinding to single button? - button

Question

I need to make multiple bindings and address them to the same button.
Right now I have this BooleanBinding:
BooleanBinding even = new BooleanBinding() {
{ super.bind(plaintextHex.textProperty()); }
#Override
protected boolean computeValue() {
return ((plaintextHex.getText().length() % 2) != 0);
}
};
And this one:
BooleanBinding maxS = new BooleanBinding() {
{ super.bind(keyHex.textProperty()); }
#Override
protected boolean computeValue() {
return (keyHex.getText().length() > 32);
}
};
If I want to assign one BooleanBinding it looks like this: crButton.disableProperty().bind(even);, but if I want to assgin muttiple I can't find any info on how to do it. The idea was that it would look something like this: crButton.disableProperty().bind(even, maxS);, but of course it doesn't work like that. Do I have to make both in the same BooleanBinding or there is a method to combine them?

Answer 1

Depending on exactly what you need, you can do
crButton.disableProperty().bind(even.or(maxS));
or
crButton.disableProperty().bind(even.and(maxS));
Or you can just create a single binding:
BooleanBinding maxSOrEven = new BooleanBinding() {
{ super.bind(keyHex.textProperty(), plaintextHex.textProperty()); }
#Override
protected boolean computeValue() {
return keyHex.getText().length() > 32 || plaintextHex.getText().length() % 2 != 0 ;
}
};
crButton.disableProperty().bind(maxSOrEven);
etc.
