在使用以下代码时,在Slider类别中而不是在科罗列小组类别内使用fireEvent()。 如何将其称为“fireEvent()”方法? (两者兼有方法的扩大活动协调委员会)

public class ColorPanel extends EventComponent<ColorChangeListener> {

public ColorPanel() {
    ...
    add(new ValueSlider());
}

.................more Code

@Override
protected void fireEvent() {
    for (ColorChangeListener l : listeners)
        l.colorChanged(color);
}

private class ValueSlider extends Slider {
    public ValueSlider() {
        super(0, 200, 200, 200);
        this.x = 10;
        this.y = 220;
        addListener(new ValueChangeListener() {
            @Override
            public void valueChanged(int value) {
                colorCircle.setValue(value / 200f);
                color = colorCircle.getSelectedColor();
                fireEvent();
            }
        });
    }
}
