Automatically resize jtable

Hi,

I'm using Eclipse to build a Java GUI (using JFC/Swing). I have a Jtable
that is part of a jPanel. However when my window resizes the table stays a
constant size. How can I resize the jTable as the window size changes?

Thanks
Frank

'Layouts'. Beyond that..
It is easier to see what you are doing wrong when you supply code.

Ah, so probably a mistake using the NULL layout option. Using eclipse it
had seemed easier to position my components if I chose NULL. But I probably
am losing some functionality by doing that.

Not *always*, but most usually.

If you wish to get x-plat compatible GUI's, layouts using
components that return logical mimimum/preferred/maximum
sizes is definitely the way to go.

About the only time you need to set a 'null' layout is
when you are creating a layout yourself, then you need to
work out how big the layout itself needs to be so that it
can return logical values to it's parent containers.

I strongly recommend working through 'Using Layout Managers'[1],
to get a feel for what is possible. Though I am not sure if
it adequately covers nested layouts..

Check out the JTable guide and look for "Adding a Table to a Container"
and "Setting and Changing Column Widths":
