refresh JFrame after adding new Components
提问by reox
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.
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，这有效，但我必须手动调整窗口大小以查看新组件。
Is there any Action I can fire or a method to call to refresh the window? Any help appreciated. Thanks in advance.
是否有任何我可以触发的操作或调用刷新窗口的方法？任何帮助表示赞赏。提前致谢。

You have to revalidate();the frame. If that doesn't work you also have to call repaint();
你必须到revalidate();框架。如果这不起作用，您还必须致电repaint();

Call
称呼
revalidate();
repaint();
revalidatetells the layout manager to reset based on the new component list. This will also trigger a call to repaint.
revalidate告诉布局管理器根据新的组件列表重置。这也会触发重绘调用。
repaintis used to tell a component to repaint itself.
repaint用于告诉组件重新绘制自身。

in java repaint();working for me. while revalidate();not working for me.
在java中repaint();为我工作。虽然revalidate();不为我工作。
