You set the data as Color
blackRadioButton.setUserData(Color.BLACK);
redRadioButton.setUserData(Color.RED);
greenRadioButton.setUserData(Color.GREEN);
blueRadioButton.setUserData(Color.BLUE);
But you try to cast it as Text
(javafx.scene.text.Text) colorToggleGroup.getSelectedToggle().getUserData();
To fix this you can use a switch statement or multiple if statements to set sample object depending on which colour is selected. Example if statement:
if ((Color) colorToggleGroup.getSelectedToggle().getUserData() == Color.BLUE) {
sample = new Text(50, 300, "Something");
}
Alternatively you can set the data for the radio buttons as Text, for example:
blueRadioButton.setUserData(new Text(50, 300, "Something"));
