JFrame Repaint（）单个组件

Question

Is it possible to repaint only a specific component in a JFrame, rather than the entire thing? 是否可以仅重绘JFrame中的特定组件，而不是整个对象？ If this is possible, how would you do this? 如果可能的话，您将如何做？

Answer 1

Yes, you can suggest the repainting of a single component by calling repaint(); 是的，您可以通过调用repaint();来建议对单个组件进行repaint(); on that component only. 仅在该组件上。 Per the Component API : 根据组件API ：

 public void repaint() 
Repaints this component. 重新绘制该组件。

If this component is a lightweight component, this method causes a call to this component's paint method as soon as possible. 如果此组件是轻型组件，则此方法将导致尽快调用此组件的paint方法。 Otherwise, this method causes a call to this component's update method as soon as possible. 否则，此方法将导致尽快调用此组件的update方法。
