Java swing setMaximumSize not working

setMaximumSize not working in java

I've having trouble with my JFrame subclass. I need to set a Maximum height.

But setMaximumSize does not work. It seems that's a bug in java (setMinimumSize works). How could prevent a JFrame from getting higher than a given height ?

Well. I use setMaximumSize on my JFrame. But I still can enlarge the JFrame above the limits I set. — Matthieu Riegler, Apr 14 '12 at 22:44

In my experience, setMinimumSize and setMaximumSize are not reliable - they may work in some situations, but often not in others

The best solution is to use a ComponentListener, implement componentResized, and enforce the min / max size that way

Can you elaborate on this? How would you enforce the min/max size by catching resize events? AFAIK these events are fired as notifications and wouldn't be helpful in enforcing size limits. – Lieuwe May 10 '16 at 08:37

Use this instead/as well:

setPreferredSize(new Dimension(width, height));

In my experience setPreferredSize(Dimension) takes preference and always works.

I usually use all of them anyway: setMinimumSize(), setMaximumSize(), setPreferredSize() and then setSize() as well
