Is there a way to customize the dot in a JavaFx RadioButton?

Hello fellow coding enthusiasts,

I am looking to find out how I can customize the color of a RadioButton dot. I want to have 3 RadioButtons, each with a different color to represent a state. Do I need to use CSS for this task? If so, could someone please guide me on how to achieve this?

An example scenario could be:

@FXML
public RadioButton redState = new RadioButton();
.
.
.
redState.setDotColor(red);

Or in FXML to statically define the color:

style="-fx-dot-color: rgb(255,0,0);"

I hope my plan is clear to everyone. The main goal is simply to change the color of the dot in a JavaFX RadioButton.

Thank you in advance for any assistance provided.

Answer №1

I have not yet experimented with this solution, but you can give it a try:

blueState.getStyleClass().add("blue-radio-button");

(or implement this in FXML if you find it easier).

After that, make sure to include the following code in an external css stylesheet:

.blue-radio-button .dot {
  -fx-mark-highlight-color: blue ;
  -fx-mark-color: blue ;
}
