javafx Radio Button Use Groups on Radio Buttons
Example
A ToggleGroup is used to manage the RadioButtons so that just one in each group can be selected at each time.
Create a simple ToggleGroup like following:
ToggleGroup group = new ToggleGroup();
After creating a Togglegroup it can be assigned to the RadioButtons by using setToggleGroup(ToggleGroup). Use setSelected(Boolean) to pre-select one of the RadioButtons.
RadioButton radioButton1 = new RadioButton("stackoverlow is awesome! :)");
radioButton1.setToggleGroup(group);
radioButton1.setSelected(true);
RadioButton radioButton2 = new RadioButton("stackoverflow is ok :|");
radioButton2.setToggleGroup(group);
RadioButton radioButton3 = new RadioButton("stackoverflow is useless :(");
radioButton3.setToggleGroup(group);
