I want to disable the button when the text fields are empty.
I have created two fields with the onKeyReleased property
Sorry i sent it unintentionally.
Something like btn.disableProperty().bind(field.textProperty().isEmpty()) should work.
In the future please add a compilable skeleton and what you have tried so far to your question. That makes it way easier to help.
