JPanel resizeble

[Uli Kunkel]

I have an applet with a few JPanels.
I want to set one JPanel not to be able to resize.
How do I do it?

Thanks in advance.

Depending on context, the following works:

panel.setMinimumSize(panel.getPreferredSize());
panel.setMaximumSize(panel.getPreferredSize());

or set appropriate constraints on the layout manager.

In the JPanel's constructor*:

setPreferredSize(new Dimension(<width>, <height));
setMaximumSize(getPreferredSize()); // prevent growth
setMinimumSize(getPreferredSize()); // prevent shrink

Alternatively, nest the JPanel in the center of a BorderLayout.

A better approach would require knowing more about your goal and
examining your sscce: <http://pscode.org/sscce.html>.

Panels will usually only resize if
a) the size of the components in it changes
(and validate and/or pack is called).
b) It is a resizable frame.

Did the application do something to make the
size of the panel change, or is it dragged
bigger and smaller?

(Much more details, in the form of an SSCCE,
could be very enlightening.)

Thank you all for the answers.
It was my mistake, I'm using NetBeans designer but somewhere in the code
I manually set the applet size..

Anyway the usual approach with this work.
