JFrame: Fixed width but dynamic height

Question

is there any way to set the width of the JFrame fixed, but height of the JFrame dynamic? For an example,

width = 1200 
Height = will be based on number of elements

in other words

width = 1200 
Height = pack()

please help!

I think you're best bet would be to restrict the width of the content pane by overriding it's `getPreferredSize` method — MadProgrammer, Mar 19 '13 at 07:43
Do not set fixed sizes. Please look at this [question](http://stackoverflow.com/questions/7229226/should-i-avoid-the-use-of-setpreferredmaximumminimumsize-methods-in-java-swi) — Amarnath, Mar 19 '13 at 07:53

Use a constant for width and a variable for height, and then use the regular setPreferredSize method

I'm pretty sure that don't stop the frame from been resized (width wise) - which is how I read the question. Also, we're generally discouraged from using setPreferredSize – MadProgrammer Mar 19 '13 at 09:30

You probably don't need this, but for future people looking at this thread, you could declare a width constant, and set min & max size of the frame.

setMinimumSize(new Dimension(WIDTH, 0));
setMaximumSize(new Dimension(WIDTH, Integer.MAX_VALUE));
setResizable(false);

Subsequent calls to pack() will enforce the width, but allow the height to be dynamically calculated.
