问题描述
我希望无论屏幕大小如何，都可以在屏幕上始终调整框架组件.我在笔记本电脑(小屏幕)中绘制框架，当我在具有大屏幕的另一台计算机(jar文件)中运行应用程序时，框架组件不会调整大小！
I want my frame components to be always adjusted in the screen, regardless of screen size. I draw the frame in my Laptop (small screen) and when I run my application in another machine (jar file) with a big screen the frame components doesn't re-size!
当我在任何机器上将框架置于全屏模式时，如何调整框架的大小?
How I can make my frame resize it's components when I put the frame in full-screen mode in any machine?

推荐答案
如果其他人也遇到相同的问题，则解决方案是使用布局而不是使用空布局.
If someone else have the same problem the solution is to use Layouts instead of using the null layout.
