Fixed size JPanel subclass

[Chris R.]

I'm trying to create a simple fixed-size, image-displaying JPanel
subclass -- what I want to do is to be able to create it with a preset
(albeit alterable manually) size and have it just display an Image of
some kind.

What methods of JPanel do I have to override to maintain total control
over the component's size?

JPanel jones = new JPanel();
jones.setBounds(new Rectangle(0, 0, 500, 500));

JPanel jones = new JPanel();
jones.setBounds(new Rectangle(0, 0, 500, 500));

Is it really that easy?

Every time I think I have control over the layout of these things,
something comes along and makes me wonder. So, with this I won't run
into layout manager noise about the size of this?

I think you can create your own subclass of JPanel and override the
getMinimumSize(), getMaximumSize(), and getPreferredSize() methods to
return whatever dimensions you would like.

getMinimumSize(), getMaximumSize(), and getPreferredSize() methods to
return whatever dimensions you would like.

There is no need to subclass for that. You can just use setMinimumSize/
setPreferredSize/setMaximumSize.

setPreferredSize/setMaximumSize.

I have never got those methods to work. I always gave up and did an
override. Is there some catch?
