自定义 Swing 组件可动态调整大小但与 LayoutManager 互操作

Question

I have a subclassed JPanel that acts as a view for some information.

When the information changes, the min/max/preferred size of the JPanel may change as well.

How do I handle this event properly so that it plays nicely with a LayoutManager ?

I tried overriding getPreferredSize() but it only seems to be called once.

Answer 1

Try revalidate your component after min/max/preferred size has been changed. Should work.
