添加新组件后刷新JFrame [英] refresh JFrame after adding new Components

问题描述

我想在运行时按下按钮时向我的JFrame添加一些新组件。
到目前为止这是有效的，但我必须手动调整窗口大小以查看新组件。

I want to add some new Components to my JFrame during runtime when a button is pressed. This works so far, but i have to resize the window manually to see the new components.

是否有任何可以触发的动作或方法来调用刷新窗口？任何帮助赞赏。在此先感谢。

Is there any Action I can fire or a method to call to refresh the window? Any help appreciated. Thanks in advance.

推荐答案

你必须 revalidate（）; 帧。如果这不起作用，你还必须调用 repaint（）;

You have to revalidate(); the frame. If that doesn't work you also have to call repaint();
