event-handling - JavaFX 单选按钮事件处理

Question

从组中选择单选按钮时会触发哪种 JavaFX2 事件，我该如何处理？

Answer 1

给定zodiacSigns的是单选按钮所属的组，

zodiacSigns.selectedToggleProperty().addListener(new OnToggleHandler());

将事件处理程序OnToggleHandler添加到按钮组（在 JavaFX 中称为切换组）。下面是代码OnToggleHandler

private class OnToggleHandler implements ChangeListener<Toggle> {

    @Override
    public void changed(ObservableValue<? extends Toggle> ov, Toggle t, Toggle t1) {
        dailyHoro.editReading(((RadioButton) t1).getText());
        dailyHoro.print();
        System.out.println("Old: " + ((RadioButton) t).getText() + ", New: " + ((RadioButton) t1).getText());
        if (dailyHoro.getText() == null)
            textEditor.setText("");
        else
            textEditor.setText(dailyHoro.getText());
    }
}
