问题 Is there a way to remove the blue frame from input filed? 回答1: The blue border you are showing is the focus border. To remove it entirely, use something like textField.setStyle("-fx-focus-color: -fx-control-inner-background ; -fx-faint-focus-color: -fx-control-inner-background ;"); or in an external css file .text-field { -fx-focus-color: -fx-control-inner-background ; -fx-faint-focus-color: -fx-control-inner-background ; } To make it the same as the unfocused text field, use .text-field

It takes a lot of time to paint the data and does not update the data when I change the values in the model(ref). I dont have a predefined data structure and so the method at this is not useful. I moved on to use
